Answer: 
Explanation:
The equation is:
The term on the left consists of a product of two different factors: therefore, this product can be zero if either the first term (2x-5) or the second term (3x-1) is equal to zero.
This means that we can solve separately for the two terms:
Solving the first equation:
Solving the second equation:
Assume x are Erica's classes & y are Bo's classes.
x+y=35
x=2y-13
Replacing the value of x into the first equation
2y-13+y=35
3y=35+13
y=16 classes
x=2*16-13=19 classes
stores revenue = $12,400
35 % of 12,400 = revenue for good advertising
= 35 / 100 × 12,400
= $4,340
so from $12,400 $4,340 was earned due to good advertising
Answer:
y = 8
Step-by-step explanation:
4t=32
Divide each side by 4
4y/4 = 32/4
y = 8
2 x (49.5 - 37.5)
2 x 12
24
Hope this helps :)
