Answer:
X=19/32
Step-by-step explanation:
3/4^2+1^2=2*x
3/4^2+1=2x
3+(4^2)/4^2=2x
3+16/4^2=2x
19/4^2=2x
19/(2^2)^2=2x
19=16(2x)
19=16*2x
32x=19
32x/32=19/32
x=19/32
This took alot of time goodluck!
Answer:
a. x=8
b.Step 1: Simplify both sides of the equation.
2(2x−2)=4x−4
(2)(2x)+(2)(−2)=4x+−4(Distribute)
4x+−4=4x+−4
4x−4=4x−4
Step 2: Subtract 4x from both sides.
4x−4−4x=4x−4−4x
−4=−4
Step 3: Add 4 to both sides.
−4+4=−4+4
0=0
Answer:
All real numbers are solutions.
c. Step 1: Simplify both sides of the equation.
3(x+1)=4x+7−x
(3)(x)+(3)(1)=4x+7+−x(Distribute)
3x+3=4x+7+−x
3x+3=(4x+−x)+(7)(Combine Like Terms)
3x+3=3x+7
3x+3=3x+7
Step 2: Subtract 3x from both sides.
3x+3−3x=3x+7−3x
3=7
Step 3: Subtract 3 from both sides.
3−3=7−3
0=4

A .625
B 1.75
C .50
D .60
The answer is C.
Answer:
Step-by-step explanation:
In order to combine like terms, you have to isolate x and y from one side of the equation.
<u>First, thing you do is remove parentheses.</u>
<u>Solve.</u>
<u>Then, you combine like terms.</u>
<u>Add/subtract the numbers from left to right.</u>
-8z+3.5z=-4.5z
<u>Rewrite the problem down.</u>
<u>Solve.</u>
4.5-1.5=3
- <u>Therefore, the correct answer is 7y+3-4.5z.</u>
I hope this helps, let me know if you have any questions.
