X + 2y = 10<br><br> y=x-4<br> Choices are:<br> (0,4)<br> (2,6)<br> (6,2)<br> (8,0) <br> Work shown
LuckyWell [14K]

Answer:

C) (6,2)

Step-by-step explanation:

Rewrite equations:

y=x−4;x+2y=10

Step: Solve y=x−4for y:

y=x−4

Step: Substitute x − 4 for y in x+2y=10:

x+2y=10

x+2(x−4)=10

3x−8=10(Simplify both sides of the equation)

3x−8+8=10+8(Add 8 to both sides)

3x=18

3x

3

=

18

3

(Divide both sides by 3)

x=6

Step: Substitute6forxiny=x−4:

y=x−4

y=6−4

y=2(Simplify both sides of the equation)

Hope this helps!

Pasha works as a food scientist. He designed a recipe for crackers that are 40% wheat flour by weight. He made a test batch of t
MA_775_DIABLO [31]
To answer this question, you need to find 40% of 1 1/2. To find a percentage of a value, you can divide the percentage by 100 and multiply that by the total.

In this situation, 40 / 100 = 0.4
So 1 1/2 x 0.4 = 0.6

Pasha will use 0.6 pounds of wheat flour in the test batch.

Solve by elimination and check. 2x+5y= 46. 3x-2y=12<br> Pls pls pls
kotykmax [81]

Answer:

x = 8, y = 6

Step-by-step explanation:

2x + 5y = 46______(1)

3x - 2y = 12_______(2)

(1) x 3 --> 6x + 15y = 138

(2) x 2 --> 6x -4y = 24

(1) - (2) --> 19y = 114

                    y = 6  sub into (2)

3x - (2 x 6) = 12

             3x = 24

               x = 8
