1*5=12.75
2*4=9.6
so nine pens cost 3.15
one pen will be 0.35$
so one pencil will be .20$
Answer:
B. 7y - 15
Step-by-step explanation:
Simplifying
10y + -3(y + 5) = 0
Reorder the terms:
10y + -3(5 + y) = 0
10y + (5 * -3 + y * -3) = 0
10y + (-15 + -3y) = 0
Reorder the terms:
-15 + 10y + -3y = 0
Combine like terms: 10y + -3y = 7y
-15 + 7y = 0
Solving
-15 + 7y = 0
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '15' to each side of the equation.
-15 + 15 + 7y = 0 + 15
Combine like terms: -15 + 15 = 0
0 + 7y = 0 + 15
7y = 0 + 15
Combine like terms: 0 + 15 = 15
7y = 15
Divide each side by '7'.
y = 2.142857143
Simplifying
y = 2.142857143
Answer:
578x gallons
Step-by-step explanation:
In order to find that we must have the rate at which fuel is consumed in travelling single mile.
If the rate of consumption of fuel is given as x gal per mile
The number of gallons consumed in 578 miles will be = 578x gallons
The terms are 2x 4y and 8 variables are x and y coefficients are 2 and 4 number is 8 hope this helped :)
