Answer: would be about 2000
Answer:
Y = 10x + 20
Step-by-step explanation:
sorry if im wrong
Answer:
140
Step-by-step explanation:
I think you mean "lowest common denominator" where you use the word "benchmark."
The LCD of 3/7 and 16/20 is 140; 140 is the smallest number evenly divisible by both 7 and 20.
Then 3/7 → 60/140 and 16/20 → 112/140. 112/140 is between 1/2 and 1.
Answer: A) 6x = 54; x = 9 times older
Step-by-step explanation:
9 x 6 = 54
Answer:
20
Step-by-step explanation:
which side is x ? the Hypotenuse - the side opposite of the 90 degree angle ? or is it one side touching the 90 degree angle ?
that is important. we need to know which side is the Hypotenuse to make the right calculations.
if I assume x is the Hypotenuse, then the calculation follows Pythagoras like this
x² = 12² + 16² = 144 + 256 = 400
x = sqrt(400) = 20
but just in case, if x is a side touching the 90 degrees angle, then the would look like this (depending on which of the other sides is the Hypotenuse)
either
12² = 16² + x²
144 = 256 + x²
-112 = x²
that did not work. a square root of a negative number did not work for actual distances.
or
16² = 12² + x²
256 = 144 + x²
112 = x²
x = sqrt(112) = 10.58
