The question doesnt seem to be repeated. From here, I'm just going to assume the hours he worked is 4. Heres what the equation would look like.

4x + 4 = r

r = total money earned
x = cost per hours worked
The plus 4 is the flat fee he charges,

I think what you are looking for is the equation on how this could be displayed.
The baseline is 4, and the hourly rate of r.
This can be shown by:
4 + r = cost

Rectangle A has a length of 12 and width of 8. Rectangle B has a length of 15 and a width of 10.

navik [9.2K]

Answer:

rectangles are similar figures, thus if scaled copies of each other then the ratios of corresponding sides must be equal

compare ratios of lengths and widths

rectangles A and B

k = = ← ratio of lengths

k = = ← ratio of widths

scale factors are equivalent, hence rectangle A is a scaled copy of B

rectangles C and B

k = = ← ratio of lengths

k = = ← ratio of width

scale factors (k ) are not equal, hence C is not a scaled copy of B

rectangles A and C

k = = ← ratio of lengths

k = ← ratio of widths

the scale factors are not equal hence A is not a scaled copy of C

Two stores are having a sale on T-shirts.Rose spends $63 for three T-shirts from store A and one from store B. Manny spends $140

Digiron [165]

Let a and b be store A and store B, respectively. Then:
3a+b=63
5a+4b=140
So
12a+4b=252
5a+4b=140
7a=112
a=16
b=15

Denise wants to burn at least 5000 calories a week through running. Based on her running speed, she estimates that she can burn

Firdavs [7]

Answer:

She will not meet her goal.

Step-by-step explanation:

There are 5 weekdays, so she will run for 0.5 * 5 = 2.5 hours over the weekdays

There are 2 weekends, so she will run for 2 * 1 = 2 hours over the weekend.

In total, this means she will run for 4.5 hours.

4.5 hours * 550 calories per hour = 2475 calories.

She will not meet her goal.
