Start off by combining like terms (your y's).
7y - 6y - 10 = 13
y - 10 = 13
Now you need to get y by itself so add 10 to both sides
y - 10 = 13
+10 +10
y = 23
Answer:

Step-by-step explanation:
D because you can see that in a b and c that there is no negative slash in d there is so it matches the question
Answer:
x = 10.3 in
Step-by-step explanation:
To find the value of a, use the area formula for a triangle. The formula is A = 1/2 *b*h. Here b = x and h= x. The formula becomes A = 1/2 *x². Substitute A = 53 and solve for x by using inverse operations.
A = 1/2x²
53 = 1/2x²
106 = x²
√106 = x
10.3 = x

Step-by-step explanation:
Both figures are cuboids whose volume (V) is calculated as
V = lbh ( l is the length, b is the width and h the height )
(8)
V = 6 × 6 × 10 = 36 × 10 = 360 ft³
(9)
V = 11 × 14 × 4 = 616 in³
