Answer:
A since if we multiply 4 × 4x, we get 16x, and 4 × 4, we get 16, which cancels with the other 16x - 16 on the left side. That makes sure that any x we choose will cancel out in the end.
Step-by-step explanation:
1. 16x - 16 = 4(4x-4)
2. 16x - 16 = 16x - 16
3. 0 = 0
In the given question, it is given that, the cost of telephone call, s, is $0.75 plus $0.25 times the number of minutes .
And we have to put the given informationin algebraic expression .
For the cost of telephone call, we have to use s and for the number of minutes, we need to use t .
So the required expression is
Values of slope = (86-71) / (3pm - 10 am) = 15 / 5 = 3
This value of the slope gives the average rise in temperature per hour.
We can expand this expression using foil method (multiply first terms, outer terms, inner terms then last terms together):
<span>(x+4)(x+6)
x^2 + 6x + 4x + 24
combine like terms
x^2 + 10x + 24
This is also the final simplified expression. It cannot be further expanded or simplified. Foil method is the easiest way to expand expressions.</span>
Answer:
Jefferson High School
Step-by-step explanation:
so the same ratio would be 12 chaperones to 210 students....12/210 reduces to 2/35
18/300 reduces to 3/50
20/350 reduces to 2/35
8/160 reduces to 1/20
14/260 reduces to 7/130
So the same ratio would be Jefferson High School
