Dee has collected no fewer than 388 coats for charities. She gave 64 of the coats to her church and donated the remaining coats equally to local shelters. If Dee gives a minimum of 36 coats to each shelter, how many shelters receive coats?

9 shelters

Step-by-step explanation:

Subtract 64 from the total number of coats to get the total amount of coats donated to shelters:

388 - 64 = 324

Then, divide 324 by 36, since that's the minimum number of coats given to each shelter:

324 ÷ 36 = 9

So at least 9 shelters received coats.

just sum

10 + 10 = 20

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
