Geoff and Max are college roommates. Geoff can clean their apartment in 2.5 hours and Max can clean their apartment in 3.25 hour

Anestetic [448]

Answer: 1.41 hours

Step-by-step explanation:

Geoff: 2.5 hours = 1 job

Max: 3.25 hours = 1 job

Together: $\frac{x}{2.5} + \frac{x}{3.25} = 1 job$

⇒ $(3.25)(2.5)\frac{x}{2.5} + (3.25)(2.5)\frac{x}{3.25} = (3.25)(2.5)1$

⇒ 3.25x + 2.5x = 8.125

⇒ 5.75x = 8.125

÷5.75 ÷5.75

x = 1.413

What is the answer and how do I solve?

8_murik_8 [283]

Because it is a 90° angle and the legs are congruent, the legs intersect with the hypotenuse at the same angle, so the other, unnamed angle at the bottom left is equal to x.

Now we can state that:

2x + 90 = 180
2x = 90
x = 45
