Answer: m=−3
Step-by-step explanation: −40−2(3m+1/2)=7m−2
−40+(−2)(3m)+(−2)(1/2)=7m+−2
−40+−6m+−1=7m+−2
(−6m)+(−40+−1)=7m−2
−6m+−41=7m−2
−6m−41−7m=7m−2−7m
−13m−41+41=−2+41
−13m/−13=39/−13
m=−3
What mistake I guess Keith did make is he subtracted 2 from -39 which equaled to -37 which caused him divide -37 by 13 when it should have been 39 divided by 13 because he should have left 39 alone and not have subtracted 2 from it also it should not have been negative basically what I'm trying to say is that he did his division and subtraction wrong.

2/3(x+6)=-8 whats the value of x?
Answers
Answer:
x=-18
Step-by-step explanation:
Answer:
The answer is -18
Step-by-step explanation:
STEP 1:
[tex]3 \times \frac{2}{3} (x + 6) = 3( - 8)[/tex]
2(x+6) = -24
______________________________________
STEP 2:
Divide both sides by 2:
[tex] \frac{2(x + 6)}{2} = \frac{ - 24}{2} [/tex]
________________________________
STEP 3:
Simplify:
[tex]x + 6 = - 12[/tex]
Subtract 6 from both sides:
[tex]x + 6 - 6 = - 12 - 6[/tex]
________________________________
STEP 4:
[tex]x = - 18[/tex]
Therefore, your answer is -18.

Jeans are on sale for 25% off. The jeans Bailee wants to buy are marked with an original price of $60. What is the total cost, in dollars, for a pair of jeans at the sale price, including a 7% tax?
Answers
7% tax = 3.15
= $48.15
I hope this helps :)
The total cost for a pair of jeans at the sale price including 7% tax is $96.30.
What is Percentage?Percentage, denoted by %, is defined as the parts of a number per fraction of 100.
We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.
here, we have,
Given that,
Original price of the jeans = $60
Discount percentage = 25%
Amount of discount = 25% × 60
= 0.25 × 60
= $15
Price of a jean at the sales price = $60 - $15 = $45
Percentage tax = 7%
Tax amount = 7% × 45 = 0.07 × 45 = $3.15
Price of the jean after tax = $45 + $3.15 = $48.15
Total cost for a pair of jeans = 2 × $48.15 = $96.30
Hence the total cost is $96.30.

A closed rectangular tank measures 5 meters by 10 meters by 6 meters. What is the surface area of the tank?
Answers
Answer:
280 square units
Step-by-step explanation:
Using the given dimensions {5, 6, 10}, find the area of the front, top and end of the box: 5*6 + 5*10 + 6*10 = 140 square units.
The back of the box is the same size and shape as the front, the bottom the same as the top, and the other end the same as the first end. Thus, multiply 140 square units by 2 to get the total surface area of the tank:
It is 280 square units.

What is Exponential Function?The formula for an exponential function is f (x) = axe, where x is a variable and an is a constant that serves as the function's base and must be bigger than 0. The transcendental number e, or roughly 2.71828, is the most often used exponential function basis.
Given equation
64w¹⁸z¹²
so factors of 64 = 2 x2 x 2 x2 x 2 x2
64 = 2⁶
the equation is 2⁶w¹⁸z¹²
Hence the value of equation is 2⁶w¹⁸z¹².
