Answer:
Unit cost: $2.50 per potato
Step-by-step explanation:
Set up a proportion:
<h2><u>5 potatoes</u> = <u>x potatoes</u></h2><h2>2 dollars 1 dollar</h2><h2 />
cross multiply:
2x = 5
divide by 2 on both sides
x= 5/2 or 2.5
Im confused what is you question?
Answer:
x = -12 x = -5
Step-by-step explanation:
-7x-60=x^2+10x
Add 7x to each side
-60=x^2+10x+7x
-60=x^2+17x
Add 60 to each side
0 = x^2+17x+60
Factor
What 2 numbers multiply to 60 and add to 17
12*5 = 60
12+5 = 17
0 = (x+12) (x+5)
Using the zero product property
x+12 = 0 x+5 =0
x = -12 x = -5
Answer:The answer is t=-12
Step-by-step explanation: First you have to simplify so the 4 is now positive. 2(t+18)+4, Subtract 4 from both sides.
2(t+18)=16−4
=12, 2(t+18)=12, now you have to divide both sides by 2. 2t/2=t and 12/2=6. t+18=6 now just subtract 18 from both sides. 18-18=0, 6-18=-12. So the answer is t=-12.
