Answer:

x=4, y=11

Step-by-step explanation:

y = -2x + 19

y = x + 7

Since both equations are equal to y, we can set them equal to each other

-2x + 19= x + 7

Add 2x to each side

-2x + 19+2x= x + 7+2x

19 = 3x+7

Subtract 7 from each side

19-7 = 3x+7-7

12 = 3x

Divide by 3

12/3 = 3x/3

4=x

Now find y

y=x+7

y = 4+7

y=11

Answer:

x = 4

y = 11

Step-by-step explanation:

y = -2x + 19

y = x + 7

Put y as x + 7 in the first equation and solve for x.

x + 7 = -2x + 19

Add 2x and -7 on both sides.

x + 7 + 2x - 7 = -2x + 19 + 2x - 7

x + 2x = 19 - 7

Combine like terms.

3x = 12

Divide both sides by 3.

3x/3 = 12/3

x = 4

Put x as 4 in the second equation and solve for y.

y = 4 + 7

y = 11

Answer:

x^{1} wives

x^{2} sacks

x^{3} cats

x^{4} kits

Suppose the man in the St. Ives poem has x wives, each wife has x sacks, each sack has x cats, and each cat has x kits. Write an expression using exponents that represents the total number of kits, cats, sacks, and wives going to St .Ives.

Step-by-step explanation:

x^{1} wives

If each of the "x" wives has "x" sacks, so the number of sacks is:

x^{2} sacks

If each of the "x" wives has "x" sacks, and each sack has "x" cats, so the number of cats is:

x^{3} cats

If each of the "x" wives has "x" sacks, and each sack has "x" cats, and each cat has "x" kits, so the number of kits is:

x^{4} kits

Hi! :)

It sounds like you need to multiply this fraction. 

\frac{3}{8}*16=6

So, Marge used 6 total inches of tape. 

Hope this helps!
