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
Answer:1
Step by step equation
Add the cost of the trip together then subtract from total cost needed to attend you would only have $360 dollars left which isn’t enough to take another students so the answer is 1
-10.1 = w + 5.3
w= -10.1 - 5.3
w= -16.4
Answer:
n³ + 6n - 4
Step-by-step explanation:
(h + g)(n) = h(n) + g(n)
= 3n - 4 + n³ + 3n ← collect like terms
= n³ + 6n - 4
