Well since you didn't provide the choices, I'll have to make some assumptions... we'll call the red pens R, the black pens B and the Blue pens x. If total cost = T then We can say...
T=R(2.50)+B(2.50)+x(2.50)
It could also be shown as
T = R + B + x(2.50)
Another way that we could have approached it since there is no difference in price between colors is just say each pack of pens (no matter the color) = P... so...
T = P (2.50)
Answer:
the last one
Step-by-step explanation:
Answer:
1. 496 people
Step-by-step explanation:
2/124 = 8/x
you have to multiply the top by 4 (2x4 = 8)
so
you multiply the bottom by 4 (124x4 = 496)
Answer:
Step-by-step explanation:
The expression 
consists of three terms:
-
These three terms have common factor 
Thus,
Consider the expression 
You can rewrite it as
The whole expression takes look
ANSWER : both angles are 60 degrees and x is equal to 8.
10x - 20 = 7x + 4
Move the terms
3x = 24
x= 8
Sub back in to find the value:
80 - 20 = 60
56 + 4 = 60
