Answer:
Step-by-step explanation:
10x+10y=-10
9x+10y=18
= 10x+10y=-10
-9x-10y=18
= x=8
step two is to find y:
10x+10y=-10
10(8)+10y=-10
80+10y=-10
10y=-90
y=-9
your answer:
(x,y)= (8,-9)

Step-by-step explanation:
Jeff made $210 by selling 30 pumpkins.
Step-by-step explanation:
Given,
Selling price of each Pumpkin = $7
Number of pumpkins sold by Jeff = 30
We will multiply number of pumpkins sold by selling price per pumpkin.
Amount made by Jeff = Price per pumpkin * Number of pumpkins
Amount made by Jeff = 7 * 30 = $210
Therefore;
Jeff made $210 by selling 30 pumpkins.

(9+w)w=252 or w(w+9)=252.
The quadratic equation applies: w²+9w-252=0=(w+21)(w-12), so w=12, because a negative zero is meaningless.
So the dimensions are width=12 in and length=21 in.
