120 * 1.75 = 200
5 times 0 = 0
5 times 2 = 10 carry the 1
5 times 1 = 5 + 1 = 6
7 times 0 = 0
7 times 2 = 14 carry the 1...
7 times 1 = 7 + 1 = 8
1 times 0 = 0
1 times 2 = 2
1 times 1 = 1
add it all together and you get 200.
Answer:
The difference between 19 and 8 is 11.
Step-by-step explanation:
Given:
The difference between a number and 8 is 11
Find the number.
Solution:
Let the unknown number be 
The difference between the unknown number can be written as:
We are given that the difference =11
So we can write the equation to find 
as :
Using additive property to solve for
Adding 8 to both sides to isolate on one side.
∴ 
∴ The unknown number = 19
Answer:
5
Step-by-step explanation:
(2x + y) - z
Let x=3 y=4 and z=5
2*3 +4 -5
Multiply and divide first
6 +4 -5
Then add and subtract
10-5
5
Subtract 350 from both sides then divide both sides by 25.
(c-350)/25 = h
Answer:
c(h) = 40*h + 50
Step-by-step explanation:
Let h be the variable that represents the number of hours
As the cable operator charges $40.00 for an hour so for h hours, the expression will be 40*h
And
Lastly, he has to charge $50.00 must as service charge,
As the number of hours is variable here so the function will be in terms of hours.
So the resulting function will be:
c(h) = 40*h + 50
