Factor using a GCF:<br> ​ 16xy2+28xy+8y
Lorico [155]

Answer:

4y( 4xy + 7x +2)

Step-by-step explanation:

16xy^2+28xy+8y

16xy^2 =2*2*2*2*x*y*y

28xy = 2*2*7 *x*y

8y = 2*2*2*y

The common factors are 2*2*y = 4y

2*2*2*2*x*y*y + 2*2*7 *x*y+2*2*2*y

2*2*y( 2*2*x*y + 7 *x+2)

4y( 4xy + 7x +2)

Y = 4x<br> y=19 - x<br> Solve the system of equations
sergey [27]

Answer:

x = 3.8

y = 15.2

Step-by-step explanation:

y = 4x

y = 19 - x,

if y = y then,

4x = 19 - x

5x = 19

x = 19/5 = 3.8 now inputting the answer to x into one of the unchanged equations above (y = 4x),

y = 4x = 4*3.8 = 15.2

Double check:

y = 19 - x = 19 - 3.8 = 15.2

Kevin and Randy Muise have a jar containing 70 coins, all of which are either quarters or nickels. The total value of the coins
Nikitich [7]

Answer:

50 nickels, 20 quarters.

Step-by-step explanation:

System of equations (q = # of quarters, n = # of nickels):

<em>q + n = 70, 0.25q + 0.05n = 7.50</em>

the first equation can be changed to q = 70 - n, so we are able to <em>substitute q with 70 - n</em>.

So, it will look like <em>0.25*70 - 0.25n + 0.05n = 7.50</em>. This can be simplified to <em>0.2n = 10</em>, which means that n = 50.

Knowing that we can solve <em>q + 50 = 70</em>, which means that q = 20.
