Answer:
Step-by-step explanation:
C = 28
C = 4 + 1/3 D
This means that
28 = 4 + 1/3 D
Subtract 4 from both sides.
24 = 1/3 D
Then to get rid of the fraction, multiply both sides by 3
72 = D
Therefore Drake is 72.
12c - 53 = 91
First add 53 to each side. This cancels it out on the left (-53 + 53 = 0)
12c = 91 + 53
12c = 144
Now divide by 12 on each side. This cancels the 12 on the left (12/12 = 1)
c = 144/12
c = 12
Answer:
Height of the building that cast a shadow of 45 meters is 27 meters
Step-by-step explanation:
This is a direct variation and let height of the object represent H and shadow represent S
Hence H∝S
H = KS, where K=constant of proportionality
K = H/S
K = 6/10 = 0.6
Hence height of a building that cast a shadow of 45 meters
H = KS
H = 0.6 × 45 = 27 meters
Answer:
100
Step-by-step explanation:
12x - 4 + 13x + 9 = 180
25x + 5 = 180
25x = 175
x = 7
13(7) + 9 = 100
