Dots sells a total of 277 T-shirts ($2) and shorts ($3). In April, total sales were $656.
icang [17]

Answer:

Shorts = 112 and t shirts = 165

Step-by-step explanation:

Let S = shorts

Let T = t shirts

T + S = 277

$2T + $3S = $656

-2(T + S) = 277          so    -2T -2S = -544

2T + 3S = 656          so      2T + 3S = 656

                                         ------------------------

SO:  (subtract T's cancel out)   1S = 112

                                           divide by 1  so S = 112

Plug S into the top equation: T + s = 277   T + 112 = 277  so T = 165

What is the slope–intercept form of the equation 4x − 2y = 9?
adelina 88 [10]
Hey there! :D

Slope intercept form: y=mx+b

4x-2y=9

Add 2y to the other side. 

4x=9+2y

Subtract 9 on both sides.

4x-9=2y

Flip the equation over. 

2y=4x-9 <== slope intercept form 

I hope this helps!

Which could be the first step in solving this system of equations by substitution?
Ainat [17]

Answer:

The first step is to replace the y in y-x=15 with 7x (we can do this because the first equation tells us that they're equal)

solve and get

(2.5,17.5)

or x= 2.5 y=17.5

Step-by-step explanation:

The first step is to recognize that y=7x which means that we can just replace the y in the second equation with 7x

7x-x=15

6x=15

x=2.5

Then we can solve for y

y=7(2.5)

y=17.5
