Answer:
No it doesn't
Step-by-step explanation:
The equation we have is
Y = 150x
We have x = 4 hours
This is a simple question. We have to plug in the x = 4 in the equation to find out if we would have 640 brushes. If y = 640, then it models it. But if y is not equal to 640, it doesn't.
So let's solve this to see for ourselves.
Y = 150(x)
We put the value of x
Y = 150(4)
Y = 600
So we can see that the equation does not model the number of brushes made each hour. This equation models 600 brushes and not 640.
Answer: yes!!!!!!!!!
Step-by-step explanation:
This is a systems of equations.
s = stamp, e = envelope
Substitute e + 9 for s.
.1(e + 9) + .13e = 2.51
Simplify.
.1e + .9 + .13e = 2.51
Simplify.
.14e + .9 = 2.51
Subtract .9 from both sides.
.14e = 1.61
Divide both sides by .14.
e = 11.5
Now, you can input e into the other equation.
11.5 + 9 = s
Simplify.
20.5 = s
s = 20.5, e = 11.5
Answer:
C 1/2
Step-by-step explanation:
7 out of 14 people have a Snap account, if you simplify that number- dividing both the numerator and denominator by 7-it leaves you with the answer 1/2
