Answer:

Step-by-step explanation:

$3x = 120 you would have to divide 3 by 3 and get 'x' by itself and then you would have to divide 120 by 3 and then you would get 40 and so then your answer would be x = 40$

Pretty sure it’s 148.10% because ofc it’s 100% and then 468-152=152 . Then 152 is 48.10 % of 316 so add that to the 100%

The solution system to 3y-2x=-9 and y=-2x+5

Alecsey [184]

Answer:

$\boxed{(3,-1)}$

Step-by-step explanation:

Hey there!

Well to find the solution the the given system,

3y - 2x = -9

y = -2x + 5

So to find x lets plug in -2x + 5 for y in 3y - 2x = -9.

3(-2x + 5) - 2x = -9

Distribute

-6x + 15 - 2x = -9

-8x + 15 = -9

-15 to both sides

-8x = -24

Divide -8 to both sides

x = 3

Now that we have x which is 3, we can plug in 3 for x in y = -2x + 5.

y = -2(3) + 5

y = -6 + 5

y = -1

So the solution is (3,-1).

Hope this helps :)

N = nickels and q = quarters

0.05n + 0.25q = 1.90
n = 2q + 3

0.05(2q + 3) + 0.25q = 1.90
0.10q + 0.15 + 0.25q = 1.90
0.10q + 0.25q = 1.90 - 0.15
0.35q = 1.75
q = 1.75/0.35
q = 5 ......there are 5 quarters

n = 2q + 3
n = 2(5) + 3
n = 10 + 3
n = 13 <=== there are 13 nickels
