Answer:
Infinite number of solutions.
Step-by-step explanation:
We have the equations,
1. 3x+3y=10
2. -9x-9y= -30
Now, if we multiply equation 1 with -3, we will obtain equation 2.
i.e. -3×(3x+3y)= -3×10
i.e. -9x-9= -30
So, we see that both the equations are same.
The equation 3x+3y=10 will have solution for many values of x and y.
Hence, the system will have infinite number of solutions.
Answer:
16
Step-by-step explanation:
Let the number be x.
37.5% * x = 6
Convert percentage to decimal form:
Multiply both sides by 1000:
Divide both sides by 375:
Answer:
Add 64
Step-by-step explanation:
x^2 - 16x
<em><u>If you add 64, you get x^2 - 16x + 64 which factors as (x - 8)^2</u></em>
