1/4 is an equivalent fraction to 2/8. Thus, since you have 7/8, you can give at most 3 friends that 2/8 slice of pizza.

Why?:

3 friends recieving 2/8 slices would be a total of 6/8. If you were to give another friend a 2/8 slice, you would be giving away 8/8 of the pizza... but you only have 7/8!!!!! Therefore, at most you can give away 6/8 to a total of 3 friends, and then you wouldn't have any 2/8 (aka 1/4) slices leftover!!

Hope that helps, cheers

On one highway, Gabriela noticed that they passed mile marker 123 at 1:00. She then saw that they reached mile marker 277at 3:00
Elena L [17]

<u>Given</u>:

Let time be the independent variable.

Let mile marker be the dependent variable.

On one highway, Gabriela noticed that they passed mile marker 123 at 1:00. She then saw that they reached mile marker 277 at 3:00 and Mr. Morales was driving at a constant speed.

The coordinates of the points on this line are (1,123) and (3,277)

We need to determine the slope of the line.

<u>Slope of the line:</u>

The slope of the line can be determined using the formula,

m=\frac{y_2-y_1}{x_2-x_1}

Substituting the points (1,123) and (3,277) in the above formula, we get;

m=\frac{277-123}{3-2}

m=\frac{154}{1}

m=154

Therefore, the value of the slope of this line is 154.

S^2-17s-60=(s-5)(s-12)<br><br> What would be wrong about this equation? What is the correct version?
Sedbober [7]
The answer is -60=60

Simplifying
s2 + -17s + -60 = (s + -5)(s + -12)

Reorder the terms:
-60 + -17s + s2 = (s + -5)(s + -12)

Reorder the terms:
-60 + -17s + s2 = (-5 + s)(s + -12)

Reorder the terms:
-60 + -17s + s2 = (-5 + s)(-12 + s)

Multiply (-5 + s) * (-12 + s)
-60 + -17s + s2 = (-5(-12 + s) + s(-12 + s))
-60 + -17s + s2 = ((-12 * -5 + s * -5) + s(-12 + s))
-60 + -17s + s2 = ((60 + -5s) + s(-12 + s))
-60 + -17s + s2 = (60 + -5s + (-12 * s + s * s))
-60 + -17s + s2 = (60 + -5s + (-12s + s2))

Combine like terms: -5s + -12s = -17s
-60 + -17s + s2 = (60 + -17s + s2)

Add '17s' to each side of the equation.
-60 + -17s + 17s + s2 = 60 + -17s + 17s + s2

Combine like terms: -17s + 17s = 0
-60 + 0 + s2 = 60 + -17s + 17s + s2
-60 + s2 = 60 + -17s + 17s + s2

Combine like terms: -17s + 17s = 0
-60 + s2 = 60 + 0 + s2
-60 + s2 = 60 + s2

Add '-1s2' to each side of the equation.
-60 + s2 + -1s2 = 60 + s2 + -1s2

Combine like terms: s2 + -1s2 = 0
-60 + 0 = 60 + s2 + -1s2
-60 = 60 + s2 + -1s2

Combine like terms: s2 + -1s2 = 0
-60 = 60 + 0
-60 = 60

Solving
-60 = 60
