You add 70 + 50 then you multiply it by 7.5 and you get, 900 gallons.
Answer:
the substitution method is one way to solve linear equation. the substitution method is when substitute the one y value with the other:
example :
x+y=10
y=10-x ( value of y)
2x+y=12 ( substitute the value of y in the equation )
2x+(10-x)=12
2x+10-x=12 ( now solve for x)
x=12-10
x=2 ( substitute the value of x in the equation x+y=10)
x+y=10
2+y=10
y=10-2
y=8
( i hope it helps)
The equation would be 4y=5x 4(x+15)=5x x+15=y
let x be the amount that Shelia deposits each time
let y represent the amount that Sherri deposits each time
4(x+15)=5x
4x+60=5x
-4x -4x
60=x
Check:
x+15=y 60+15=y y=75
4(75)=5(60)
300=300
Shelia deposits $60 each time.
Answer: x^5+5x^4+x^3
Step-by-step explanation:
assuming the expression is x^3(x^2+5x+1) each term in the bracket is multiplied by x^3
x^3(x^2+5x+1)
=(x^3*x^2)+(x^3*5x)+(x^3*1)
=x5+5x^4+x^3
Answer:
I'm not sure but I believe the correct answer is line L2.
Step-by-step explanation:
It seems to be closer to more points than the other lines.
If it is not L2, it must be L3.
