Answer:

The answer is t=2m+5

Step-by-step explanation:

because she is painting 2 every month so 2*m and she started with 5 so you have to add the 5.

After 1 month she would have 7 paintings because 2*1=2 and add the 5.

After 2 months she would have 9 paintings becuase 2*2=4 and add the 5.

This would continue with each month.

There are 45 new houses being built in a neighborhood Last month, 1/3 of them were sold. This month, 1/5 of the remaining houses
goldfiish [28.3K]
1/3 of 45 is 15.

So 45-15= 30.

1/5 of 30 is 6.

So 30-6=24.

There are 24 houses left to be sold.

Cole is studying employment trends.
natali 33 [55]

Answer:

225

Step-by-step explanation:

So we know that 20% of the social workers he surveyed was 45 people. The easiest way to find all 100% of the social workers is to do 45 x 5 because 20% x 5 = 100%. So 45 x 5 = 225.

Hope this helped! :)

Steffie makes a scale drawing for a crate with the demensions 15 inches long by 12 inches wide. Her scale factor is 1:3. Brian m
rodikova [14]

Answer:

Dimensions → (5 inches × 4 inches)

Step-by-step explanation:

Scale factor used for the drawing by Steffie = \frac{1}{3}

Since, scale factor = \frac{\text{Dimension of the drawing}}{\text{Actual dimension}}

For Steffie,

Actual length of the crate = \frac{\text{Dimension of the drawing}}{\text{Scale factor}}

                                           = \frac{15}{\frac{1}{3}}

                                           = 45 inches

Actual width of the crate = \frac{12}{\frac{1}{3} }

                                         = 36 inches

Since Brian used the scale factor = \frac{1}{9}

Length of the drawing = Actual length × Scale factor

                                     = 45 × \frac{1}{9}

                                    = 5 inches

Width of the drawing = Actual width × Scale factor

                                   = 36 × \frac{1}{9}

                                   = 4 inches

Therefore, dimensions of the drawing made by Brian are (5 inches × 4 inches)
