Answer 1

Problem 11

Answer:  h = 2A/b

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

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

Answers:Equation:   (n+2)/5 = 14Solution 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

Answer: Not a solution

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

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.

If lin runs 21 laps at the same rate, how long does it take her 25.6 minutes How many laps per minute is that? __ laps

Answers

Answer: 0.82 laps per minute

Step-by-step explanation:

Lin is running 21 laps in 25.6 minutes.

Solve the equation:

7x − 2 = 26

Answers

Answer:

[tex] \large \boxed{x = 4}[/tex]

Step-by-step explanation:

Goal

Solve for x-term.

Given

Equation

[tex]7x - 2 = 26[/tex]

Step 1

Isolate x by adding 2 to both sides.

[tex]7x - 2 + 2 = 26 + 2 \\ 7x + 0 = 28 \\ 7x = 28 \\ x = \frac{28}{7} \\ x = 4[/tex]

Step 2 (Optional)

We check the answer by substituting x = 4 in the equation.

[tex]7x - 2 = 26 \\ 7(4) - 2 = 26 \\ 28 - 2 = 26 \\ 26 = 26[/tex]

The equation is true for x = 4. Hence, the solution is x = 4.

Which expression is equivalent to 7h^2-252k^2?

A. 7(h-6k)^2
B. 7(h-18k)^2
C. 7(h-6k)(h+6k)
D. None of these

Answers

Answer:

c

Step-by-step explanation:

252 = 7 *36

36 = 6 *6 = 6²

a² -b²  = (a + b)(a - b)

7h² - 252k² =  7(h² - 36k²)

                   = 7(h² - [6k]² )

                  = 7(h  +6k)(h - 6k)

Lynn took a taxicab from the office to the airport. She paid $4 per mile plus a $6 flat fee. Her total cost was $66. How many miles was the trip?

Answers

Answer:

12

Step-by-step explanation:

Answer:

15 miles

Step-by-step explanation:

To answer this question, we must break up the question. First, we know Lynn paid a total of $66 for the trip. She had to pay $4 per mile, and the flat fee was $6, meaning that no matter how many miles they rode, she had to pay an extra $6 on top of that. So, we can subtract the total cost by the flat fee:

66 - 6 = 60

Then, we divide that number by the amount it costs to ride each mile, which is 4:

60 / 4 = 15

So, Lynn's trip was 15 miles

Hope this helps :)
