Answer:
14.4 ft
Step-by-step explanation:
The triangles formed by both ladders are similar to each other. Therefore, each corresponding sides will be proportional.
Thus, x + 8 would represent how far up the 10-foot ladder reaches the wall.
Therefore:
18/10 = (x + 8)/8
9/5 = (x + 8)/8
Cross multiply
9*8 = 5(x + 8)
72 = 5x + 40
72 - 40 = 5x
32 = 5x
Divide both sides by 5
32/5 = x
x = 6.4
The 10-foot ladder would be, 6.4 + 8 = 14.4 ft far up the wall.
4^3 + 4*5
4^3 = 64
64 + 4*5
4*5 = 20
64 + 20 = 84
84 is the simplest answer.
Gary will take to exercise a total of 21 hours in 4 weeks. And the equation will be 5.25x = 21.
<h3>What is the linear system?</h3>
A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
Gary exercises 1.75 hours on Mondays, Wednesdays, and Saturdays.
So in a week, Gary exercises 5.25 hours.
She will take time to exercise 21 hours will be
Let she will take x week, then the equation will be
5.25x = 21
x = 4
