Solve for x. −2x + 3b > 5 x > the quantity 3 times b minus 5 all over 2 x > the quantity 5 minus 3 times b all over negative 2 x < the quantity 3 times b plus 5 all over 2 x < the quantity negative 3 times b plus 5 all over negative 2
Answer:
x < the quantity negative 3 times b plus 5 all over negative 2
Step-by-step explanation:
−2x + 3b > 5
Subtract 3b from both side.
-2x +3b -3b > 5-3b
-2x > 5-3b
Divide by -2 on both sides, remember to flip the inequality since we are dividing by a negative
-2x/-2 < 5/-2 - 3b/-2
x < (5-3b)/-2
x< (-3b+5)/-2
Re write in words.
x is less than the quantity negative 3 times b plus 5 all over negative 2

someone deposits rs 40000 in a bank at the rate of 5%p.a. if he hsa to pay 5% of interest as income tax, how much will he get after 4 years
If someone deposits Rs 40000 in a bank at the rate of 5% p.a. after paying 5% tax, the amount he will get after 4 years is Rs 47600.
How the amount is determined:
Principal amount (P) = Rs. 40000
Rate of interest (R) = 5% per annum
Time period (T) = 4 years
We can calculate the simple interest using the formula:
[tex]\text{Simple Interest} = \frac{{P \cdot R \cdot T}}{{100}}[/tex]
Plugging in the values:
[tex]\text{SI} = \frac{{40000 \times 5 \times 4}}{{100}}[/tex]
= Rs 8000
Total Income after 4 years = Principal + Interest
Total Income = 40000 + 8000 = Rs 48000
Income Tax on Interest: The income earner needs to pay 5% income tax on the interest earned
Tax to Pay = 5% of Rs 8000 = Rs 400
Final Amount Received after Tax = Total Income - Tax to Pay
= 48000 - 400
= Rs 47600
Complete Question:
If someone deposits Rs 40000 in a bank at the rate of 5% p.a. If he has to pay 5% of interest as income tax, how much will he get after 4 years?

Find the difference
In a certain chemical, the ratio of zinc to copper is 3 to 13. A jar of the chemical contains 286 grams of copper. How many grams of zinc does it contain?
Answer:
The jar of chermical contains 66g of Zinc.
Step-by-step explanation:
The ratio of Zinc to Copper is 3 : 13
A jar of the chemical contains 286g of copper.
Let the mass of the Zinc be xg.
[tex]\frac{13}{3}[/tex] = [tex]\frac{286}{x}[/tex]
x = [tex]\frac{3 × 286}{13}[/tex] = 66g
So the jar of chemical contains 66g of Zinc.
To determine the grams of zinc in a jar of a chemical with a zinc to copper ratio of 3 to 13 and 286 grams of copper present, calculate the value of one part in the ratio (286 grams / 13) and multiply by the number of parts of zinc (3), resulting in 66 grams of zinc.
The student wants to find out how many grams of zinc are in a jar of chemical, given that the ratio of zinc to copper is 3 to 13 and there are 286 grams of copper. To solve this, we can use the concept of ratios. The ratio of zinc to copper is 3:13, which means for every 3 parts of zinc, there are 13 parts of copper.
First, let's find the value of one 'part' in the ratio by dividing the total amount of copper (286 grams) by 13 parts:
1 part = 286 grams / 13 = 22 grams
Now, to find the amount of zinc, we multiple the number of zinc parts (3) by the weight of one part (22 grams):
Amount of zinc = 3 parts / 22 grams per part = 66 grams
So, the jar contains 66 grams of zinc.
Students at East Central High School earned $535 selling candles. They want to make $2570 for a club trip. What percent of their goal has been reached?
Answer:
21%

In triangles △KHJ and △LGW, m∠K=m∠L, m∠H=m∠G, KH=8, LG=4, GW=2.5, and KJ=LW+3. Find the unknown sides of these triangles.
Answer:
KJ = 6 , LW = 3 , KJ = 6
Step-by-step explanation:
Let LW be x then KJ be x + 3
In ΔKHJ and ΔLGW,
∠K = ∠L and ∠H = ∠G , So, by AA Similarity, [tex]\Delta KHJ \sim\Delta LGW[/tex]
Therefore,
[tex]\frac{8}{4}=\frac{x+3}{x} =\frac{HJ}{2.5}[/tex]
First taking,
[tex]\frac{8}{4}=\frac{x+3}{x}\\8\cdot x = 4\cdot x + 12\\4\cdot x=12\\x=3[/tex]
∴LW = 3 , KJ = 6
Now,
[tex]\frac{8}{4}=\frac{HJ}{2.5}[/tex]
⇒ HJ = 5
The unknown sides of the triangle KHJ and triangle LGW are HJ = 5, LW = 3, and KJ = 6 and this can be determined by using the given data.
Given :
m∠K=m∠Lm∠H=m∠GKH = 8, LG = 4, GW = 2.5, and KJ = LW + 3Given that m∠K = m∠L, m∠H = m∠G, therefore, triangle △KHJ and △LGW are congruent to each other by AA similarity postulate.
To determine the unknown sides of the given triangles, first, let the unknown side LW be 'a' and the side KJ be 'a + 3'.
[tex]\rm \dfrac{8}{4}=\dfrac{a+3}{a}=\dfrac{HJ}{2.5}[/tex] ----- (1)
[tex]2\times a = (a+3)\times 1[/tex]
2a = a + 3
a = 3
Put the value of 'a' in equation (1).
[tex]\rm \dfrac{3+3}{3}=\dfrac{HJ}{2.5}[/tex]
[tex]\rm 2\times 2.5 = HJ[/tex]
HJ = 5
LW = 3
KJ = 3 + 3 = 6
The unknown sides of the triangle KHJ and triangle LGW are HJ = 5, LW = 3, and KJ = 6 and this can be determined by using the given data.

In the first week students at RSM solved 25 percent of their monthly quota of problems. In the second week, they solved 110 percent of the number of problems solved in the first week. In the third week they solved 60 percent of the number of problems they had solved in the first two weeks and, in the fourth week, they solved the remaining 320 problems. How many problems did students solve in the four-week month?
Answer:
2,000 problems
Step-by-step explanation:
We know the students solved the following amount of problems:
Week 1 - 25% of the month
Week 2 - 110% of the first week--> this means 25(1.10)=27.5%
Week 3 - 60% of the first two week--> this means 0.6(25+26.5)=31.5%
Week 4 - 320 problems --> this is 16% of the quota since 100-25-27.5-31.5=16%
So we know that 320 is 16%. We can set up a proportion to find the total amount.
[tex]\frac{16}{100} =\frac{320}{y}[/tex]
We solve by cross multiplying by multiplying numerator and denominator on opposite fractions.
[tex]16(y)=100(320)\\16y=32000\\\frac{16y}{16}=\frac{32000}{16}\\ y=2,000[/tex]
The quota for the month is 2,000 problems.

Answer:
y = 48° is the answer.
Step-by-step explanation:
In the figure attached, length of small arc = 66°
This small arc makes an angle at the center of the circle = 66°
By definition, angle formed by the arc at the center is double of the measure of the angle inscribed by the small arc at the point on a circle.
Therefore, m (arc) = 66° = 2.(x)

You’re welcome to say medication five days earlier. The number of milligrams of medication and no wells body is about what percentage of the number of milligrams and Carrie’s body anytime after they both have taken the medication
Answer:
7.8%
Step-by-step explanation:
can I get Brainliest???
The percentage of the number of milligrams and Carrie’s body anytime after they both have taken the medication is less than 100%.
How to find how much percent 'a' is of 'b'?Suppose a number is 'a'
Suppose another number is 'b'
We want to know how much percent of 'b' is 'a'.
Then, it is calculated as:
[tex]\dfrac{a}{b} \times 100[/tex]
(in percentage)
We are given that;
Carrie is prescribed 600 mg of a medication.
The medication decays at a rate of 40% per day.
Now,
Let's first find the amount of medication remaining in Carrie's body after taking the medication for 5 days:
m = 600(0.6)^5
m ≈ 86.18 mg
To find the percentage of the amount of medication in Carrie's body after 5 days compared to anytime after they both have taken the medication, we need to find the amount of medication in Carrie's body at any given time, t. We can use the same formula and substitute t for d:
m = 600(0.6)^t
Now, we can calculate the percentage of the amount of medication in Carrie's body after 5 days compared to any time after they both have taken the medication:
(m after 5 days / m at any time) x 100%
= (86.18 / 600(0.6)^t) x 100%
= (0.1436 / 0.6^t) x 100%
Since we don't know the exact value of t, we can't simplify this expression any further. However, we can make some observations:
As t increases, the denominator (0.6^t) gets smaller, so the fraction as a whole gets larger.
When t is very large, the fraction approaches 0, which means that the amount of medication in Carrie's body approaches 0, or she has eliminated all the medication from her body.
Therefore, we can conclude that the percentage of the amount of medication in Carrie's body after 5 days compared to any time after they both have taken the medication will be less than 100%,
