Bob finds the absolute value of −4.4, and then finds the opposite of his answer. Glen finds the opposite of −4.4, and then finds

Sergio039 [100]

1. The absolute value of -4.4 is 4.4

2. The opposite of 4.4 is -4.4

So, Bob's answer is -4.4

1. The opposite of -4.4 is 4.4

2. The absolute value of 4.4 is 4.4

So, Glen's answer is 4.4

Glen's answer is larger than Bob's.

Box dimensions: 5 x 5 x 8

2 faces: 5 x 5 -> 2 * 5 * 5 = 50

4 faces: 5 x 8 -> 4 * 5 * 8 = 160

Total = 50 + 160 = 210 sq in

Y = 3x + 15 3x + 3y = 9

Zina [86]

Answer:

$\Large\boxed{x=-3}$ $\Large\boxed{y=6}$

Step-by-step explanation:

Given the system of equations

$1)~y=3x+15$

$2)~3x+3y=9$

Divide 3 on both sides of the 2) equation

$3x+3y=9$

$3x\div3+3y\div3=9\div3$

$x+y=3$

Current system

$1)~y=3x+15$

$2)~x+y=3$

Substitute 1) equation into the 2) equation

$x+(3x+15)=3$

Combine like terms

$x+3x+15=3$

$4x+15=3$

Subtract 15 on both sides

$4x+15-15=3-15$

$4x=-12$

Divide 4 on both sides

$4x\div4=-12\div4$

$\Large\boxed{x=-3}$

Substitute the x value into one of the equations to find the y value

$y=3x+15$

$y=3(-3)+15$

$y=-9+15$

$\Large\boxed{y=6}$

Hope this helps!! :)

I don't understand this nonsense !

Well first you do 6÷3=2. Then you do 2*5= 10. Also do 20+10=30-15=15. So your answer is 15
