Since the two numbers vary directly, if Y is quadrupled, X will do the same. 2 times 4 is 8, 15 times 4 is 60.
X = 60.
Hope that helps!! :)
So work =time times rate or W=TR
so T=m-k
W=(m-k)R
if you want just m-k then m-k is the answer
Answer:3/4 inch
Step-by-step explanation:
Answer:
y=2, x=-1
Step-by-step explanation:
We can add the two equations together to eliminate x:
6x+5y+(-6x)+7y=4+20
12y=24
y=2
We plug y into the first equation and get
6x+5(2)=4
6x+10=4
6x=-6
x=-1
Answer:
4x²×(1+7x)
