QT = RS
30 = 4x + 10
20 = 4x
x = 5
answer
x = 5 It's B. second choice
Answer:
15x+45-2x=15x-2x-10
13x+45=13x+10
13x-13x=10-45
if you simplify further
you will not get an answer there is a mistake in the question
4 and 3/4 = 4.75
13/24 = .541666
4.75 + .541666 = 5.2916
Answer:
20 feet
Step-by-step explanation:
Lance the alien is 5 feet tall. His shadow is 8 feet long. At the same time of day, a tree's shadow is 32 feet long. What is the height of the tree?
We solve this using proportion of
Height/ Shadow
= 5/8 = x/32
Cross Multiply
8x = 5 × 32
x = 5 × 32/8
x = 20 feet
The height of the tree is 20 feet
