X=number of years that Ethas was 5 times older than his son.
we suggest this equation:
40-x=5(12-x)
40-x=60-5x
-x+5x=60-40
4x=20
x=20/4=5
answer. 5 years.
Answer:
a= 81m^2
Step-by-step explanation:
we know the top triangle: the base is 9
a = 1/2(bh)
a = 1/2 (9 x 8)
a = 1/2 (72)
a = 36
the parallelogram at the bottom has base 9 and height 5
a = bh
a = 9 x 5
a = 45
add them together 36 + 45 = 81
Answer:
MK = 23
Step-by-step explanation:
Rectangle means that the angles are all 90 degrees, so all the sides are not tilted in any direction. Meaning the JL = MK, therefore:
2x + 5 = 7x - 40
subtract 5 from both sides
2x = 7x - 45
subtract 7x from both sides
-5x = -45
divide by -5
x = 9
Now input 9 into the equation
MK = 7(9) - 40 = 63 - 40 = 23
nevermind about my answer then oops
Answer:
⅜ is the distance
