Answer:
<h2>The easiest to solve for is x in the first equation</h2>
Step-by-step explanation:
Given the system of equation, x + 4 y = 14. and 3 x + 2 y = 12, to solve for x, we can use the elimination method of solving simultaneous equation. We need to get y first.
x + 4 y = 14............ 1 * 3
3 x + 2 y = 12 ............ 2 * 1
Lets eliminate x first. Multiply equation 1 by 3 and subtract from equation 2.
3x + 12 y = 42.
3 x + 2 y = 12
Taking the diffrence;
12-2y =42 - 12
10y = 30
y = 3
From equation 1, x = 14-4y
x = 14-4(3)
x = 14-12
x = 2
It can be seen that the easiest way to get the value of x is by using the first equation and we are able to do the substitute easily <u>because the variable x has no coefficient in equation 1 compare to equation 2 </u>as such it will be easier to make the substitute for x in the first equation.

The boss is correct because if you press the button 5 time knowing that if u press it one time it is going to have the photo at 7.04 inches so if you keep going by the time you get to 5 times it is going to about 4.22 so you would have had to press it 4 times which would equal 5.4 inches
The volume is 108 cubic inches
The formula for a pyramid is 1/3(Bh), where B= is the base, and h is the height. The base is 6*6 or 36 and the height is 9. Therefore, the volume is (36*9)/3 or 108
Take the number "of" divided by the other number then multiply it by 100% to get the percentage.
(21/33.5) ×100%= 62%
