No, Mr.Evans will make under $400. His base pay, 9.20 times the hours he worked at regular pay(40) would equal $368. Now, take those extra 2.25 hours he worked at 1.5 times his base pay of 9.20, which would give you $13.80. Now, multiply 13.80 and 2.25, and you get 31.05. These two amount added, would equal $399.05, leaving Mr. Evans at just under $400 earned that week.

2x+4y=12 y=0.25x-3 What is the solution to the system of equations?
ololo11 [35]
{ 2 x + 4 y = 12
   y = 0.25 x -3

Arrange equation variables of elimination :

{ 2 x + 4 y = 12
 -0.25 x  + y = - 3

Multiply  ( -0.25 x +y = - 3 )  by 8 :

8y - 2 x =  - 24 

{ 2 x + 4y = 12
  -2x + 8y  = -24
----------------------
        12 y = -12

y = - 12 / 12

y = - 1

For x :

2 x  + 4y = 12

2 x + 4 ( - 1 ) = 12

2 x - 4 = 12

2 x = 12 + 4

2 x =  16

x = 16 / 2

x = 8

x = 8 and y = - 1  =>  ( 8 , - 1 )

Answer b

hope this helps!

Can someone help me solve this?
Dovator [93]

Answer:

5 felt pads.

7 cards.

Step-by-step explanation:

Remark

  • The total number of items is 12
  • So let the felt sheets be x
  • Let the cards = y

Equations and Solution

x + y = 12

Now the price is 7.75 that she has to pay for the 12 items. She wants to come back with 0 dollars.

0.5x + 0.75y = 7.75             Multiply this equation by 2

x + 1.5y = 15.50                    write the first equation underneath and subtract.

<u>x +    y =   12</u>

      .5y =  3                          Divide by 0.5

y = 3/0.5

y = 7

So she can get 7 cards.

x + y = 12

x + 7 = 12

x = 12 - 7

x = 5

So she can buy 5 felt pads.
