Answer:
21.66666667
Step-by-step explanation:
3x-4(0)=65
3x=65
x=21.66666667
You replace y wil 0 when you are sovling for x
Answer:
x = 30
Step-by-step explanation:
if A||B, then 4x + 2x must equals to 180 (interior angles of 2 parallel lines)
6x = 180
x = 30
We are given that T = test score, and x = # of hours studied. We are given the same information in numbers:
T = 90
x = 6
y = ?
We need to figure out y in terms of k. Let's set up what we know:
Let's multiply both sides by y to get rid of it on the right side:
Now, let's divide by 90 on both sides to get rid of it from the left side (and solve for y):
Your answer is A! If any part didn't make sense, you know where to reach me.
Answer:
16 + x2 = 0 (16)
I THINK
Step-by-step explanation: Simplifying
3x2 + 48 = 0
Reorder the terms:
48 + 3x2 = 0
Solving
48 + 3x2 = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-48' to each side of the equation.
48 + -48 + 3x2 = 0 + -48
Combine like terms: 48 + -48 = 0
0 + 3x2 = 0 + -48
3x2 = 0 + -48
Combine like terms: 0 + -48 = -48
3x2 = -48
Divide each side by '3'.
x2 = -16
Simplifying
x2 = -16
Reorder the terms:
16 + x2 = -16 + 16
Combine like terms: -16 + 16 = 0
16 + x2 = 0
The solution to this equation could not be determined.
First you would plug in 6 for x because x=6.
8(-5(6)+3)
then you would just solve
parentheses first so
8(-35+3)
8(-32)
=-256
