Solve the equation 96 - 4.5y - 3.2y = 5.6y + 42.80. Show your work.

Answers

Answer 1

96 - 4.5y - 3.2y = 5.6y + 42.80

96 - 7.7y = 5.6y + 42.80

96 = 5.6y + 42.80 + 7.7y

96 = 13.3y + 42.80

96 - 42.80 = 13.3y

53.2 = 13.3y

4 = y

hope that helps, God bless!

Answer 2

96 - 42.80 = 4.5y + 3.2y + 5.6y
(opposite signs when you cross over the equal sign)
53.2=13.3y

53.2/13.3=y
4=y

if h(x)=3^x-7 find h(4) show all work
[tex]h(x) = {3}^{x} - 7[/tex]

Answers

Just substitute 4 for x in the given equation:

h(4) = 3^4 - 7 = 81 - 7 = 74 (answer)

h(x) = (3^x) - 7
h(4) = (3^4) - 7 ... replace every x with 4; then use PEMDAS to simplify
h(4) = 81 - 7
h(4) = 74

Answer: 74

Side Note: 3^4 means we have four copies of '3' being multiplied together
3^4 = 3*3*3*3 = 9*9 = 81

Walter is mixing cement for his new patio. He knows he needs to water-to-cement ratio of 20-30. What percent of his total mixture is water?

Answers

The ratio of water to cement is 20:30 meaning that for every 20 parts of water, we have 30 parts of cement. There are 20+30 = 50 parts total.

Divide the number of parts of water (20) over the total number of parts (50)
20/50 = 2/5 = 0.40
use a calculator or long division to find the decimal form of 2/5 to be 0.40

Then move the decimal point 2 spots to the right to go from 0.40 to 40%

Answer: the percent of water in the mix is 40%

Final answer:

To find the percentage of water in Walter's mixture with a water-to-cement ratio of 20-30, the water part is 20 out of 50 total parts, which equates to 40% of the mixture being water.

Explanation:

Walter needs a water-to-cement ratio of 20-30 for his patio cement mixture. To find out what percent of his total mixture is water, we can interpret the ratio as a fraction and then convert that fraction to a percentage. The fraction for water is 20 parts out of a total of 20 (water) + 30 (cement) parts, which is 20/50. To convert this to a percentage, we multiply by 100%.

Calculating the percentage: (20/50) × 100% = 40%

Therefore, 40% of Walter's total mixture is water.

angle P and angle Q are supplementary. If angle P = 2x and angle Q = x-3, find X

Answers

2x+x-3=180
3x-3=180
3x=183
x=61

The angles P and Q are supplementary, meaning together they add up to 180 degrees. Based on the given expressions for these angles, solving for x yields x equals 61.

The given problem describes supplementary angles P and Q. Supplementary angles are two angles whose measures add up to 180 degrees. In this case, angle P is represented by 2x and angle Q is represented by x-3. The equation representing these supplementary angles is therefore 2x + (x - 3) = 180.

Combining similar terms, this equation simplifies to 3x - 3 = 180. To solve for x, add 3 to both sides obtaining 3x = 183. Finally, divide each side by 3 to find x = 61.

Marco and Drew stacked boxes on a shelf. Marco lifted 9 boxes and Drew lifted 14 boxes. The boxes that Drew lifted each weighed 8 lb less than the boxes Marco lifted. Let m represent the weight of the boxes that Marco lifted.Which expression represents the total number of pounds Drew lifted?14(m−8)112m9(m+8)m−8

Answers

We let m be the weight of the boxes Marco lifted. From the problem statement, each box that Drew lifted is eight pounds less than Marco's boxes. It can be represented by (m-8). To find for the total number of pounds Drew lifted, we multiply the expression above by the number of boxes he lifted which is 14. Therefore, the correct answer is option B, 14(m-8).

if m = weight of boxes and the boxes drew lifted were 8 pound less you would have (m-8)

Marco lifted 14 boxes so the equation would be 14(m-8)

Write 2036017 in expanded form using exponents

Answers

2 × 10 to the 6th power + 0 × 10 to the 5th power + 3 × 10 to the 4th power + 6 × 10 to the 3rd power + 0 × 10 to the 2nd power + 1 × 10 to the 1st power + 7 × 10 to the 0 power

The value of 2036017 in expanded form using exponent is expressed as (2 × 10⁶) + (3 × 10⁴) + ( 6 × 10³) + 10¹ + 7

Given the value 2036017, we are to express it in expanded form as shown:

2036017 = 2,000,000 + 30000 + 6000 + 10 + 7

Express each term as exponents

2,000,000 = 2 × 10⁶

30000 = 3 × 10⁴

6000 = 6 × 10³

10 = 10¹

Taking the sum of the exponents

2036017 = (2 × 10⁶) + (3 × 10⁴) + ( 6 × 10³) + 10¹ + 7

Hence the value of 2036017 in expanded form using exponent is expressed as (2 × 10⁶) + (3 × 10⁴) + ( 6 × 10³) + 10¹ + 7

Prove that triangle ABC must be isosceles

Then find <DCB: 180º - 90º - nº = 90-nº

Angle <ACB doesn't change: it is 90-n

but, <ABD is only part of <ABC: if we add <ABD with <DBC then we get 90-2n+n = 90-n

Definition of an isoceles triangle: It has two sides that are congruent or has two angles that are congruent.

Because both <ABC and <ACB equal 90-n the triangle ABC is an isoceles triangle.

Convert: y>3/2x-7/2 from point slope to standard form?

Answers

The goal is to get the inequality into the form Ax+By > C or Ax+By < C

First multiply both sides of the inequality by 2 to clear out the fractions
y > (3/2)x - 7/2
2*y > 2*( (3/2)x - 7/2 )
2y > 2*( (3/2)x ) + 2*( -7/2 )
2y > 3x - 7

Now get the x and y terms to one side; move the 7 to its own side
2y > 3x - 7
2y+7 > 3x - 7+7 ... add 7 to both sides
2y+7 > 3x
2y+7-2y > 3x-2y ... subtract 2y from both sides
7 > 3x-2y
3x-2y < 7 ... flip the two sides and the inequality sign

We finally have the inequality into the form Ax+By < C where
A = 3
B = -2
C = 7

---------------------------------------------

The answer is 3x-2y < 7
