Answer:

  • white: 15
  • yellow: 10

Step-by-step explanation:

Let y represent the number of yellow sweatshirts sold. Then the total revenue is ...

  $11.95(25 -y) +$12.50(y) = $304.25

  $0.55y +$298.75 = $304.25 . . . simplify

  $0.55y = $5.50 . . . . . . subtract $298.75

  y = 10 . . . . . . . . . . divide by $0.55

  25-y = 15 . . . . the number of white sweatshirts sold

10 yellow and 15 white sweatshirts were sold.

Tito solved this equation. 2(3x+5)=22+5x-3x.
Lelechka [254]

Hello from MrBillDoesMath!

Answer:

x = 3

Discussion:

Remark: if Tito solved the equation why didn't he tell you what the solution was ?  );   Guess I'll have to do it myself....

2(3x+5) = 22 + 5x - 3x                 => 2(3x+5) = 6x + 10 and 5x-3x = 2x

6x + 10 = 22 + 2x                         => subtract 2x for both sides

6x - 2x + 10 = 22                          => subtract 10 from both sides

4x = 22-10 = 12                             => divide both sides by 4

x = 12/4 =3

Thank you,

MrB

A city planner is rerouting traffic in order to work on a stretch of road. The equation of the path of the old route can be desc
earnstyle [38]

Answer: D

Explanation:

The equation of a line in the point slope form is expressed as

y - y1 = m(x - x1)

where

m represents slope

x1 and y1 represents coordinates of the point that the line passes.

From the information given, the equation of the path of the old route is

y = 2x/5 - 4

Recall, the equation of a line in the slope intercept form is expressed as

y = mx + c

By comparing both equations,

slope, m = 2/5

If two lines are parallel, it means that they have the same slope. Given that the new route is to be parallel to the old route and will go through point (Q, P), then

m = 2/5

x1 = Q

y1 = P

The equation of the new route be

y - P = 2/5(x - Q)
