We have that if we add 4 to the number of charter schools, we have twice the number of the alternative schools in the county. Hence, twice the alternative schools are 52. The half of this is 26. Hence, there are 26 alternative schools in the county. These steps correspond to solving the expression 48=4+2x.
Answer:
63
Step-by-step explanation:
Set up the proportion
(6x+3)/17 = (8x - 1)/21 Cross Multiply
21 * (6x + 3) = 17 (8x - 1) Remove the brackets
126x + 63 = 136x - 17 Subtract 126x from both sides
63 = 136x - 126x - 17 Combine
63 = 10x - 17 Add 17 to both sides
63 + 17 = 10x Combine the left
80 = 10 x Divide by 10
80/10 = x
x = 8
Now you want 8x - 1
8*8 - 1 = 63
