I'm having a little difficulty finding the area because I forgot how the get the height... if I knew the height I would tell you.
I am so sorry I can not help all the way.
but if you find the height Area= base (11) times height (?)
Answer:
x=6
Step-by-step explanation:
2 (x-4) +3 =7
Subtract 3 from each side
2 (x-4) +3-3 =7-3
2(x-4) =4
Divide each side by 2
2(x-4)/2 = 4/2
x-4 = 2
Add 4 to each side
x-4+4 =2+4
x=6
Answer:
15 miles
Step-by-step explanation:
Steve runs 3.5 miles in 30 minutes (0.5 hours). So his speed is:
r = 3.5 mi / 0.5 h
r = 7 mi/h
If his rate increases to 7.5 mi/h, the distance he runs in 2 hours is:
d = 7.5 mi/h × 2 h
d = 15 mi
Using the commutative property would be: 4*9=36
