Hello!
Your answer is: 7
(X = "<em>A number</em>")
<em>"11 more than four times a number is 39"</em> in equation form is: 4X + 11 = 39
to solve, first subtract 11 from both sides:
4X = 28
then divide both sides by 4 to get:
X = 7
I hope this helps, and have a nice day!
Answer:7feet
Step-by-step explanation:
perimeter(p)=54ft
Width(w) +13=Length(L)
Perimeter=2xLength+2xwidth
P=2xL+2xw
L=w+13
54=2(w+13)+2w
54=2w+26+2w
Collect like terms
54-26=2w+2w
28=4w
Divide both sides by 4
28/4=4w/4
7=w
Width =7feet
Line Q, you always want the line that has as many dots on it as possible!! :)
If you multiply 48cm times 15cm,you get 720cm.Which would leave you with 60 left because 780 minus 720 equals 60.The height of the other base is 60cm.
