3x + 2(-2x + 3) = 50 |use distributive property
3x - 4x + 6 = 50
-x + 6 = 50 |subtract 6 from both sides
-x = 44 |change signs
x = -44
Answer:
35
Step-by-step explanation:
what you gotta do is multiply 5 * 7 to get 35
Answer:
118.625
Step-by-step explanation:
Lets clear this up.
M = $65.
6 months = 182.5 days
We may turn 65 into a decimal for a more exact answer.
<h3>
65 = 0.65 (changing it to a decimal does not change the value.)</h3>
Now we can do
182.5 x 0.65
= 118.625.
For your homework you could say.
"6 months is 182.5 days, we would need to change 65 into a decimal, which is 0.65 to get a more exact answer. 182.5 x 0.65 = 118.625. Sally will be paid 118.625 in 6 months."
0.125 sorry if I’m wrong :(
Part (a)
<h3>Answer: x = -8</h3>
------------------
Work Shown:
2(x-1) = 3(x+2)
2x-2 = 3x+6 .... distribute
2x = 3x+6+2 .... adding 2 to both sides
2x = 3x+8
2x-3x = 8 .... subtracting 3x from both sides
-x = 8
x = -8 ..... multiply both sides by -1
===========================================================
Part (b)
<h3>Answer: x = 5/11</h3>
------------------
Work Shown:
-4(2x-2) = 3(x+1)
-8x+8 = 3x+3 ..... distribute
-8x = 3x+3-8 .... subtract 8 from both sides
-8x = 3x-5
-8x-3x = -5 ... subtract 3x from both sides
-11x = -5
x = -5/(-11) .... divide both sides by -11
x = 5/11
In decimal form, this is approximately equal to 5/11 = 0.4545
