Answer:
2
Step-by-step explanation:
2L + 6 = 6L - 10 Add 10 to both sides
2L + 6 + 10 = 6L Combine the left.
2L + 16 = 6L Subtract 2L from both sides
16 = 6L + 2L Combine the right
16 = 8L Divide by 8
8L = 16
8L/8 = 16/8
L = 2
Answer:
C
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= 
, substituting values
= 
( cross- multiply )
21x = 7(24 - x) ← distribute
21x = 168 - 7x ( add 7x to both sides )
28x = 168 ( divide both sides by 28 )
x = 6 → C
Draw a diagram! Lets say the width is x, then the length must be 2x.
Area = length x width
2x x x = 8sq meters
2x^2 = 8
x^2 =4
x = √4
x = 2
we found the width the length is two times the width, making it 4 meters.
Answer:
x=40
Step-by-step explanation:
first you simplify both sides of the equation, then you isolate the variable
40/4= 10
10 times 3/2 = 15
