Answer:
7 ft
Step-by-step explanation:
Let x be the shorter and y be the longer length
x + y = 10
x = 10 - y
4x = 2y - 2
4(10 - y) = 2y - 2
40 - 4y = 2y - 2
6y = 42
y = 7
The options are as follows
(1) An object that is filled
(2) Covering the outside of an object
(3) An object that is solid
(4) Cubic units
(5) Square units
Answer:
(1) An object that is filled
(3) An object that is solid
(4) Cubic units
Step-by-step explanation:
Clues that applies
(1) An object that is filled: By filling means that object has that amount of volume that is being filled completely.
(3) An object that is solid is likely a clue to finding the volume of an irregularly shaped solid.

Answer:
together they have 60
Step-by-step explanation:
B= number of balloons billy has
A =adams balloons
Adam had 30 less balloons than Billy
A = B-30
After Billy gave 5 balloons to Adam, the number of Adam's balloons was half of the number of Billy's balloons.
1/2(B-5) = A+5
1/2 (B-5)-5 =A
set the two equations equal A = B-30 equal to 1/2(B-5)-5 = A
B-30 = 1/2(B-5)-5
add 5 to each side
B-30 + 5 = 1/2 (B-5)
B - 25 = 1/2 ( B-5)
multiply by 2
2(B-25) = 2* 1/2 (B-5)
distribute
2B-50 = B-5
subtract B
2B-50 -B =B-B -5
B-50 = -5
add 50
B-50+50 = -5+50
B = 45
Now we need to find out A
A = B-30
A = 45-30
A = 15
Billy has 45
Adam has 15
together they have 45+15
together they have 60
