Challenge: Perla worked 4 hours at her job on Saturday and then spent $12.75, in the supermarket, on her way home. She worked 5

hours on Sunday and earned 1.5 times her normal hourly rate because it was a holiday. She spent $8.50, at the florist, on her way home on Sunday. If Perla had $70.75 after her spending, determine her normal hourly rate.
Write and solve an equation.
Note:
decide what your variable represents (example: x is number of hours)
only use 1 variable.

W=normal hourly wage

4W-12.75+5*1.5W-8.50=70.75

4W-12.75+7.5W-8.50=70.75

11.5W-21.25=70.75

11.5W=92

W=8

Normal hourly rate is $8/hour

Check

32-12.75+60-8.50=70.75

y=-x

slope for perp line = 1

2y=-x+6

y=-1/2x +3

slope for perp line = 2

15.

i don’t wanna do all sorry it’s a lot of work so i’ll tell u how to do it instead. first write it in slope intercept form which is

y-y1=m(x-x1)

it’s parallel which means it shares the same slope. if it’s perpendicular it would be opposite reciprocals so for -3/2 the perp slope would be 2/3.

the line is

y+1=3/4(x-4)

we distribute the 3/4 so it’s now

y+1=3/4x-3

then we subtract the 1

y=3/4x-4 is the equation boom done

Francine applies the commutative property to the product. (−8/9)⋅(−13)⋅(18) Which expression illustrates the commutative propert
oksian1 [2.3K]

The commutative property implies that, the order of multiplication is not important.

(-\frac 89) \cdot (18) \cdot (-13) is true

Commutative property of multiplication states that:

If a \times b  = b \times a

The expression is given as:

(-\frac 89)\cdot (-13) \cdot (18)

To get the commutative expression, we simply change the position of each factor in the expression.

So, some possible equivalent expressions are:

(18) \cdot (-13) \cdot (-\frac 89)

(18)\cdot (-\frac 89) \cdot (-13)

(-13) \cdot (18) \cdot (-\frac 89)

There are several other equivalent expressions.

From the list of options;

(-\frac 89) \cdot (18) \cdot (-13) is true

 Ill Mark Brainliest if you answer correctly. The figure below shows a shaded circular region inside a larger circle:
pogonyaev

First we have to find the areas of both circle using the formula

Area = \pi r^2

For larger circle,

Area=  \pi(5)^2 = 25 \pi

For smaller circle,

Area = \pi (4)^2 = 16 \pi

Required probability

= \frac{25 \pi -16 \pi}{25 \pi} *100 = \frac{9}{25}*100 = 36%

Correct option is the second option .
