Answer: c
Step-by-step explanation:
ANSWER: 2y^2 + 13y +51 r(219/y-4)
picture explanation too:
Rate=progress/time
progress=number of tomatoes
are rates the same aka are they equal?
20/2=35/3.5?
10=35/3.5
10=70/7
10=10
true
yes they are
Answer:
y=1 , z=-2
Step-by-step explanation:
I will use the method of elimination :
Multiply the top equation by 5 to make equation 3 :
35z + 15y = -55
Multiply bottom equation by 3 to make equation 4:
6z + 15y = 3
Subtract equation 3 from equation 4 to eliminate the y :
-29z = 58
Divide both sides by -29 to solve for z :
z = 58 ÷ -29
z = -2
Substitute this value into either equation 1 or 2 to solve for y :
I chose equation 2 :
2(-2) + 5y = 1
-4 + 5y = 1
Add 4 to both sides :
5y = 5
Divide both sides by 5 :
y = 1
Hope this helped and have a good day
