Answer:
First awnser
Step-by-step explanation:
4x(7-v2)+v7(7-v2)
28-4v2+7v7-v14
Area of a rectangle is just length x height.
It probably looks confusing because of the numbers. So just change them into only inches; 12 inches in a foot.
So the rectangle is 10ft, 10inches tall...or 10*12+10=130inches
The rectangle is 2ft 11inches wide...or 2*12+11=35 inches
So now just multiple 130*35=4550 inches^2
Answer:
Did the question get cut off?
a = -(1/5)
b = 1
c = 0
Step-by-step explanation:
y = x/5 may be rewritten as y = (1/5)x
y = (1/5)x
y - (1/5)x = 0
- (1/5)x + y + 0 = 0
ax + by + c = 0
a = -(1/5)
b = 1
c = 0
I believe the answer is B) 50
Answer:
-60 3/4m
Step-by-step explanation:
The diver first dives down 50 1/4m, which is represented by the -50 1/4m. He then descends another 10 1/2m down. So -50 1/4m - 10 1/2m.
-50-10=-60
-(1/4)-(1/2)= (1/4)+(1/2)
(1/4+1/2)=(2/8+4/8) you can only add with the same denominators.
=6/8 (simplifies down to 3/4)
