Answer:

13) 90-18 = 72

14) 108/9 = 12

15) 66+34 = 100

16) 7*8 = 56

Step-by-step explanation:

All you need to do is take the second term of each equation and move it to the other side. So for number 16 we just need to move the 8 from the left to the right. This is as simple as multiplying both sides by 8 to get:

8*(56/8) = 8(7)

56 = 8*7

And that would be the answer to number 16!

Jasmine has taken an online boating safety course and is now completing her end-of-course exam. As she answers each question, th

dsp73

Answer:

There are 60 total questions on the course exam.

Step-by-step explanation:

Given that:

Number of questions finished by Jasmine = 12

Percentage shown on the bar = 20%

The total number of questions will be 100%, therefore, 20% of the questions are equal to 12.

Let,

x be the total number of questions on the course exam

20% of x = 12

$\frac{20}{100}x=12\\0.2x=12$

Dividing both sides by 0.2

$\frac{0.2x}{0.2}=\frac{12}{0.2}\\x=60$

Hence,

There are 60 total questions on the course exam.

The plans for a rectangular deck call for the width to be 10 feet less than the length. Sam wants the deck to have an overall pe

sergeinik [125]

Length of deck is 40 feet

<h3><u><em>Solution:</em></u></h3>

Sam wants the deck to have an overall perimeter of 60 feet

Perimeter of rectangular deck = 60 feet

Let "L" be the length of rectangle and "W" be the width of rectangle

Given that plans for a rectangular deck call for the width to be 10 feet less than the length

Width = length - 10

W = L - 10 ------ eqn 1

<em><u>The perimeter of rectangle is given as:</u></em>

perimeter of rectangle = 2(length + width)

Substituting the known values we get,

60 = 2(L + L - 10)

60 = 2(2L - 10)

60 = 4L - 20

80 = 4L

L = 20

Thus the length of deck is 20 feet
