Answer:
8+3*25, 83,2^3+3*5^2, are all equivalent
Step-by-step explanation:
Answer:
They are the same.
Step-by-step explanation:
The graphs are same because <em>x</em>² is always positive, so the absolute value part is redundant.
Answer: The answer is 6n+7y
Step-by-step explanation: All you have to do is add like terms
Answer : 96
x – y = 16 --------> equation 1
1/8 x + 1/2 y = 52
x is the higher grade and y is the lower grade
We solve the first equation for y
x - y = 16
-y = 16 -x ( divide each term by -1)
y = -16 + x
Now substitute y in second equation
1/8 x + 1/2 ( -16 + x ) = 52
1/8x - 8 + 1/2 x = 52
1/8x + 1/2x - 8 = 52
Take common denominator to combine fractions
1/8x + 4/8x -8 = 52
5/8x - 8 = 52
Add 8 on both sides
5/8x = 60
Multiply both sides by 8/5
x = 96
We know x is the higher grade
96 is the higher grade of Jose’s two tests.
