ziggy sells coffee and donuts , the total number of cofees and donuts ziggy sells today is 100. Ziggy charges 3$ for coffee and
sergejj [24]
You use a system of equations
x= coffee
y= donuts
x+y=100
3x+y=180
there’s 3 ways to solve system of equations substitution graphing and elimination. it would be easiest to use substitution here. So you multiply x+y=100 by -1 so it become -x-y=-100. then you combine it with the other equation and get 2x=80 so x=40 which means 40 cups of coffee were sold then you plug it back in to find y. 40+y=100. y=60.
y= 60 (donuts). x= 40 (coffee)

Solve using Combining Like Terms (CLT)<br><br> 7 + 4d + 5d = 7d + 3
Vesnalui [34]

Answer:

d= -2

Step-by-step explanation:

7 + 4d + 5d = 7d + 3

Combine like terms

7+9d = 7d+3

Subtract 7d from each side

7+9d-7d = 7d-7d+3

2d +7 = 3

Subtract 7 from each side

2d+7-7 = 3-7

2d = -4

Divide each side by 2

2d/2 = -4/2

d = -2
