Answer:
24m - 28
Step-by-step explanation:
Given the expression (6m−7)⋅4, we are to simplify it. Using the distributive law;
A(B+C) = AB + AC [A is distributed over B and C]
For the expression (6m−7)⋅4, we will distribute 4 over 6m and -7 as shown;
(6m−7)⋅4 = 4(6m) - 4(7)
(6m−7)⋅4 = 24m - 28
Hence (6m−7)⋅4 = 24m - 28
<u>Answer:</u>
−12 ÷ 4 expression best shows the temperature change each hour. Hence Option C is correct
<u>Solution:</u>
Given that, the temperature has been going down at a constant rate.
In 4 hours it went down by 12 degrees.
Now, we have to choose the correct option which best describes about the change in temperature for each hour.
Now, we know that, 12 degrees decreased in 4 hours.
Then, number of degrees decreased in one hour = 
Number of degrees changed in one hour = 
Because the temperature is decreasing we have to add a (-) symbol before the change in degrees.
So, now, <em>number of degrees changed in 1 hour </em>= 
Hence, the correct option is option c.

Answer:
n = 98
Step-by-step explanation:
8/11 x (n - 10) = 64
multiply both sides of the equation by 11/8
11/8 x 8/11 x (n-10) = 11/8 x 64
reduce the numbers with greatest common divisor 11
1/8 x 8 (n-10) = 11/8 x 64
n - 10 = 11 x 8
multiply the numbers
n - 10 = 88
so then you add the numbers
n = 88 + 10
n= 98
Answer:
81
Step-by-step explanation:
We need to know the sides of the square so 36÷4=9
Area of a square = Side x side
Area of square = 9x9=81
