It will not last the entire shift.
Answer:
d) 12(100) + 12(80) + 12(5)
Step-by-step explanation:
According to the distributive property, if a,b, c, and d are real numbers, then
a(b+c+d)=ab+ac+ad
We want to find the product 12(185).
We can expand 185 as 100+80+5
Our product then becomes;

We expand using the distributive property to get;

The correct choice is D
Answer:
y=-3/13x-89/13
Step-by-step explanation:
m=y²-y¹/x²-x¹
m=(-8)-(-5)/5-(-8)
m=-3/13
y-y=m(x-x1)
y-(-8)=-3/13(x-5)
y+8= -3/13x+15/13
-8 -8
y=-3/13x-89/13
-4x + 7y = 9 ⇒ -4x + 7y = 9 ⇒ 8x - 14y = -18
2y = -5x - 22 ⇒ -5x - 2y = 22 ⇒ <u>-35x - 14y = 154</u>
<u>43x</u> = <u>-172</u>
43 43
x = -4
-4x + 7y = 9
-4(-4) + 7y = 9
16 + 7y = 9
<u>- 16 - 16</u>
<u>7y</u> = <u>-7</u>
7 7
y = -1
(x, y) = (-4, -1)
