Please help with 11,12,13
faltersainse [42]

Problem 11

<h3>Answer:  h = 2A/b</h3>

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

Explanation:

We need to get h by itself. To do so, we first multiply both sides by 2. Then we divide both sides by b

A = (1/2)*b*h

2A = b*h

b*h = 2A

h = 2A/b

================================================

Problem 12

<h3>Answers:</h3>
  • Equation:   (n+2)/5 = 14
  • Solution to that equation:  n = 68

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

Explanation:

The number n is increased by 2 to get n+2

Then we divide by 5 to get (n+2)/5

This is set equal to 14 to get the equation (n+2)/5 = 14

Solving the equation would look like this

(n+2)/5 = 14

n+2 = 5*14 .... multiply both sides by 5

n+2 = 70

n = 70-2 .... subtract 2 from both sides

n = 68

================================================

Problem 13

<h3>Answer: Not a solution</h3>

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

Explanation:

We'll replace every copy of x with -3 and simplify

-2x + 5 > 13

-2*(-3) + 5 > 13

6 + 5 > 13

11 > 13

The last inequality is false because 11 is not greater than 13. Since the last inequality is false, this makes the first inequality false when x = -3.

Therefore, x = -3 is not a solution.

Tom made a vegetable pizza and a pepperoni pizza. he cut the vegetable pizza into 5 slices and the pepperoni pizza into 10 equal
Anon25 [30]
I may not be the best at this but I believe that Tom’s friends ate the same amount of pepperoni pizza to vegetable pizza because He cut the pizza into 5 slices as to the pepperoni into 10 slices is. The fraction of Vegetable to Pepperoni is 1/2 so 2 vegetable slices is the same amount as 4 slices because the pepperoni pizza is in smaller sizes compared to the Vegetable pizza.
