Answer:
C and D
Step-by-step explanation:
Let's add this all together.
9x + 5y + x - 3y
Combine like terms 5y + -3y and 9x + x
10x + 2y
So we know D is at least correct.
What else? C is also correct, because we can expand it outward.
10x + 5y - 3y = 10x + 2y
A and B are not correct! We can't multiply the ys or the xs.
Answer:

Answer:
Step-by-step explanation:
Start with this equation where 17 is the base, x is the power that 17 must be raised to. Then 2 is the result.
17^x = 2 Take the log of both sides
log(17^x) = log(2) Take the x outside the brackets
x log(17) = log(2) Divide by log 17
x = log(2)/log(17) Find the values for log 2 and log 17
log(2) = 0.3010
log(17) = 1.230
x = .3010/1.230
x = .2446
Answer: he percentage of height of A is 85% and the percentage of height of B is 135% and it can be evaluated by using unitary method.
Step-by-step explanation:
he percentage of height of A is 85% and the percentage of height of B is 135% and it can be evaluated by using unitary method.
Given :
To ride on roller coaster you must be 40 inches tall.
Unitary method is used to find the percentage of height of A and percentage of height of B. Single unit is determined first in the unitary method and than multiply the single unit to find the necessary value.
Applying unitary method to determined the percentage of height of A.
Divide 34 by 40.
Multiply the above value by 100.
= 85%
Again applying unitary method to determined the percentage of height of B.
Divide 54 by 40.
Multiply the above value by 100.
= 135%
The percentage of height of A is 85% and the percentage of height of B is 135% and it can be evaluated by using unitary method.
