Answer:
At end of summer, the Maple is 19.44 feet
Step-by-step explanation:
We need to find 8% of 18 feet and add it to 18 to get the new height.
To get percentage to decimal, we need to divide by 100. Hence
8/100 = 0.08
8% of 18 is:
18 * 0.08 = 1.44 feet
Now, we need to add this to 18 feet. We have:
18 + 1.44 = 19.44 feet
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:
-21
Step-by-step explanation:
(m*n)/p + ( -n )
4(9)/-3 + (-9) = (36/-3) - 9
-12 - 9 = -21
