Answer:
25 and 18
Step-by-step explanation:
To evaluate an expression, substitute the values x=6 and y=4 into each expression. Replace the x and y with these values then simplify.
9x - 29 ------> 9(6)-29 = 54 - 29 = 25
7y - 10 ------> 7(4) - 10 = 28 - 10 = 18
Answer:
15(3+2x)
Step-by-step explanation:
Factor out the 15.
Just plug in the numbers:
4: 16 + 24 = 40 YES
5 = 25 + 40 ≠ 40 NO
8: 64 + 48 ≠ 40 NO
10: 100 + 60 ≠ 40 NO
So A. is the correct answer. Just to be sure:
-10: 100 + ( - 60) = 40
Your answer is A. Hope that helps! :)
Answer:
The percentage error of measurement is 5.63 %
Step-by-step explanation:
Given as :
The measure length of the fence = 150 feet
The actual length of the fence = 142 feet
Let the percentage error in measurement = x
So, x = ×100
Or, x = ×100
or, x = ×100
or, x = 5.63 %
Hence The percentage error of measurement is 5.63 % Answer
