<em>So to solve for a variable, you have to isolate that variable onto one side.</em>

<h3>14.</h3>

Firstly, multiply both sides by j: h-4=kj

Next, divide both sides by k and <u>your answer will be: \frac{h-4}{k}=j</u>

<h3>15.</h3>

Firstly, add g on both sides: \frac{x}{5}=a+g

Next, multiply both sides by 5 and <u>your answer will be: x=5(a+g)</u>

<h3>16.</h3>

Firstly, subtract 5p on both sides: 9c=-4p

Next, divide both sides by 9 and <u>your answer will be c=-\frac{4}{9}p</u>

Which of the following ordered pairs
ozzi

The ordered pairs  that make this equation true is (4, 10)

A linear equation is given by:

y = mx + b;

where y, x are variables, m is the slope of the line and b is the y intercept.

Given the linear equation: y = 10x - 30:

At (1, -12): y = 10(1) - 30 = -20 ≠ -12

At (8, 1): y = 10(8) - 30 = 50 ≠ 1

At (4, 10): y = 10(4) - 30 = 10

At (6, 20): y = 10(6) - 30 = 30 ≠ 20

The ordered pairs  that make this equation true is (4, 10)

Answer:

12m

Step-by-step explanation:

Given that the area of the square  DVD case is 144 square cm

Since Area = L²

144 =L²

L = √144

L = 12m

Since the width of the DVD and its case are the same, hence the with of the DVD is also 12m
