The answer to 1/7 of 21 is 3.
I'm going to guess it's G. 2/5 because i divided 20 by 8, don't know if it helps!
<span>5x-0.1=4x
Subtract 5x from both sides so that the x variable is only on one side
-0.1=-x
Divide both sides by -1 to get rid of the negative on the side with the x variable
Final Answer: 0.1=x</span>
The width in inches would be 12, because of the formula:
length x width = perimeter
so you would do it reverse!
perimeter/length = width
so, 144/12 = 12
Answer:
C) 16
Step-by-step explanation:
f(x)=2x^2+4x+10
Let x = -3
f(-3) = 2(-3)^2 +4(-3) +10
= 2(9)- 12+10
= 18 -2
= 16
