The answer is 5x-5that is the answer
So to set up the equation we have:
<span><span><span>4M</span><span>4+M</span></span>=<span>127</span></span>
<span>28M=12(4+M)</span>
<span>28M=48+12M</span>
<span>28K−12M=48</span>
<span>(28−12)M=48</span>
<span>16K=48</span>
<span>M=<span>4816</span></span>
<span>M=3</span>
So Marna can clean the chimney alone in 3 hours

The only possible value of x is 3, since we can't operate logarithm with a negative integer in it.

Multiply total students by the percentage:
600 x 80% = 600 x 0.80 = 480
480 students want more field trips.
Answer:
1. x=-6
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3(2x+3)−4x=−3
(3)(2x)+(3)(3)+−4x=−3(Distribute)
6x+9+−4x=−3
(6x+−4x)+(9)=−3(Combine Like Terms)
2x+9=−3
2x+9=−3
Step 2: Subtract 9 from both sides.
2x+9−9=−3−9
2x=−12
Step 3: Divide both sides by 2.
x=-6
