Solve for e. 9e-7=7e-11
Answers
Reorder the terms: -7 + 9e = 7e + -11
Reorder the terms: -7 + 9e = -11 + 7e
Solving -7 + 9e = -11 + 7e
Solving for variable 'e'. Move all terms containing e to the left, all other terms to the right.
Add '-7e' to each side of the equation. -7 + 9e + -7e = -11 + 7e + -7e Combine like terms: 9e + -7e = 2e -7 + 2e = -11 + 7e + -7e
Combine like terms: 7e + -7e = 0 -7 + 2e = -11 + 0 -7 + 2e = -11
Add '7' to each side of the equation.
Combine like terms: -7 + 7 = 0 0 + 2e = -11 + 7 2e = -11 + 7
Combine like terms: -11 + 7 = -4 2e = -4
Divide each side by '2'. e = -2
Simplifying e = -2
The value of e is -2.
To solve the equation 9e - 7 = 7e - 11, follow these steps:
Move all terms involving e to one side of the equation:
9e - 7e = -11 + 7
Combine like terms:
2e = -4
Divide both sides by 2 to solve for e:
e = -2
Thus, the value of e is -2.

b. How many oranges will be in each basket?
c. How many bananas will be in each basket?
d. How many pears will be in each basket?
Answers
B. 6 oranges
C. 9 pears
D. 4 bananas
Hope this helps! Let me know if you need any further assistance!
Answer:
a. Maximum 3 baskets
b. Number of oranges = 6
c. Number of bananas = 4
d. Number of pears = 9
Step-by-step explanation:
Peter has 18 oranges, 27 pears and 12 bananas.
He wants to prepare the fruit baskets with the same number of each fruit in each basket.
a). Greatest number of fruit baskets can be prepared by calculating highest common factor.
Factors of 18 = 2×3×3
Factors of 27 = 3×3×3
Factors of 12 = 2×2×3
Now highest common factor of 18, 12 and 27 = 3
Therefore, maximum 3 baskets can be prepared.
b. Number of oranges in each basket = [tex]\frac{18}{3}=6[/tex]
c. Number of bananas in each basket = [tex]\frac{12}{3}=4[/tex]
d. Pears in each basket = [tex]\frac{27}{3}=9[/tex]
Danielle is saving to buy a flat screen television that cost $510. She wants to know how long it will take to save the money and writes the expression 510 ÷ [(35×11)]. Will Daniels expression help her find how long it will take to save the money she needs? Explain your answer.
Answers
Danielle's expression doesn't provide the correct time frame for saving unless $385 is her savings rate. She needs to divide the cost of the television by her regular savings amount to find the needed time to save.
Explanation:Danielle is trying to figure out how long it will take to save enough money to buy a flat screen television that costs $510. However, her expression 510 ÷ (35×11) will not accurately give her the information she needs unless $385 (which is 35×11) represents her monthly savings or some other specific saving interval. To determine how long it will take to save the money, Danielle would need to know her savings rate per week, month, or another interval of time and then divide the total cost of the television by that rate.
For example, if Danielle can save $50 each month, the correct expression would be $510 ÷ $50/month. This would yield 10.2 months, assuming she can save that amount consistently every month without any additional costs or interest. Budgeting and cutting unnecessary expenses can also help Danielle accelerate her savings plan. If she finds ways to increase her savings rate by reducing discretionary spending, she would be able to purchase her desire faster.

Two bicyclists are 180 miles apart when they start racing towards each other. If their speeds are 14 mph and 16 mph respectively, how long will it be before they are twenty miles apart?
Answers
14 + 16 = 30 m in one hour.
(because they're both moving towards each other, so for the amount they get closer to each other, you want to add both of their speeds)
Since they were originally 180 miles apart, and you want to find how long it would take for them to be 20 miles apart, you want to just subtract 20 from 180 to find the total distance they have to travel.
180 - 20 = 160
Now divide 160 by 30 to find out how many sets of 30 miles, or one hour time periods, there are in 160 miles.
160 / 30 = 16/3 hours.
To make this into minutes, you can just multiply by 60.
16/3 * 60 = 960/3
960/3 = 320
So it'll be 320 minutes before they are 20 miles apart.
5.3 hours, or 319.999 or 320 minutes
Explanation:
If the bicyclists are 20 miles apart, they have travelled 160 miles in total because:
180 - 20 = 160
Make an equation for the bicyclists traveling 160 miles total:
14x + 16x = 160
Solve for x:
14x + 16x = 160
30x = 160
30x ÷ 30 = 160 ÷ 30
x = 5.3
So after 5.3 hours, both bicyclists have traveled 160 miles, and are 20 miles apart.
5.3 hours in minutes is
60 • 5.3 = 319.99 or 320 minutes.

the ratio of boys to girls in a class is 5:4 there are 36 students in the class how many students are girls
Answers
5 + 4 = 9
Now we need to know the value of each part
36 / 9 = 4
The girls has total of 4 parts, therefore we can just multiply the number of parts by the amount in each part
4 x 4 = 16
So there r 16 girls in the class
Final answer:
To find the number of girls in the class, you calculate the value of each part of the ratio by dividing the total number of students by the sum of the ratio parts, and then multiply the result by the number of parts for girls, which gives us 16 girls.
Explanation:
The question involves finding the number of girls in a class where there is a given ratio of boys to girls and a total number of students. In this case, the ratio of boys to girls is 5:4, and there are 36 students in the class. To solve for the number of girls, we can use the concept of ratios. First, combine the parts of the ratio to find the total parts in the ratio, which is 5 + 4 = 9 parts. Each part is then equal to the total number of students divided by the total parts, which is 36 students \/ 9 parts = 4 students per part. Since the ratio of boys to girls is 5:4, we know that girls constitute 4 parts of the total. Thus, the number of girls can be calculated by multiplying 4 (the number of parts for girls) by 4 students per part, resulting in 16 girls in the class.

a=p（1+rt） solve r answer
Answers
A = p（1+rt）
A = p + prt
A - p = prt
(A - p)/pt = r
Done.
In the simple interest formula a=p(1+rt), r can be solved by rearranging the formula to r = [a/p - 1] / t.
Explanation:The question involves the formula a=p(1+rt) which you would normally see in simple interest calculations in mathematics. Your task is to solve for r (the rate).
To do that, you could rearrange the formula: r = [a/p - 1] / t
So, to calculate r, you would subtract one from the quotient of a and p, then divide that result by t (the time).
