It takes adi2 hours to drive from home to her office and 3 hours if she drives 15 mph slower. what is the distance between adi's house and the office?
i will give you a brainliest i swear to god
hurry

90 miles

Step-by-step explanation:

2 hours = work

speed = x

Distance to work = y

y = 2x

y = 3(x - 15)

3 * x = 3x

3 * -15 = -45

y = 2x

y = 3x - 45

Let's graph this (attached below)

We must find the point at which they intercept.

They intercept at (45, 90)

That means that x = 45 and y = 90

So, she is 90 miles from her office.

Let's check our work:

y = 2(45)

y = 3(45) - 45

y = y

y = 90

2 * 45 = 90

3 * 45 = 135

135 - 45 = 90

This proves that y = y and that y = 90.

55% are girls and 45% are boys : ) hope this

step-by-step explanation:

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8
