Answer: x=y/(12-5c)
Step-by-step explanation:
To solve for x, we need to use algebraic properties.
We notice that each term on teh right side contains an x. We can factor out an x.
y=12x-5cx [factor out x]
y=x(12-5c) [divide both sides by 12-5c]
x=y/(12-5c)
Clear parentheses and combine like terms:
Answer:
[tex] -40s + 90t + 30 [/tex]
Step-by-step explanation:
Given, [tex] -10(4s - 9t - 3) [/tex]
To clear parenthesis using the distributive property of multiplication, we have,
[tex] -10(4s) -10(-9t) -10(-3) [/tex]
Negative sign multiplied by negative sign = positive sign
[tex] = -40s + 90t + 30 [/tex]
Thus:
[tex] -10(4s - 9t - 3) = -40s + 90t + 30 [/tex]

Sam made ten to add 7 + 2 + 6 Enter number to complete the equation. Sam first added 7 + 2 = 9. Then he made 10 to find the find the sum. The sum is 4 + 6 = 10 + ? = ?
Answer:
So we have the addition.
7 + 2 + 6.
First, she added the 7 + 2 = 9
So we can replace that in our addition as:
7 + 2 + 6 = (7 + 2) + 6 = 9 + 6
Now, we can use 9 = 5 + 4, and replace that in the addition.
Then we have:
9 + 6 = (5 + 4) + 6
And we know that 4 + 6 = 10.
Then:
5 + 4 + 6 = 5 + (4 + 6) = 5 + 10 = 15.
How are rational numbers and Integers similar? How are they different?
Answer:
Every integer is a rational number, since each integer n can be written in the form n/1. For example 5 = 5/1 and thus 5 is a rational number. However, numbers like 1/2, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers. They are different because Integers include all whole numbers and their negative counterpart e.g. … -4, -3, -2, -1, 0,1, 2, 3, 4,… is a rational number but not an integer. All rational numbers belong to the real numbers. If two numbers are at the same distance from 0 as in the case of 10 and -10 they are called opposites.

∠GEF = (5x - 3)°
Find:
value of x
Computation:
∠DEF = ∠DEG + ∠GEF

if angle DEF equals 117 find the value of X
Answer:
x= 7
Step-by-step explanation:
add (12x+1) and (5x-3) which becomes 17x-2 and then set that equal to 117 and solve. move the 2 to the right side of the equation which becomes 17x=119 and then divide 119 by 17 which x equals 7.
plug in 7 for x to make sure you get 117

An investor earned 5 times the profits of what she earned last year. If she made \(\$613801.5599999999\) total for both years, how much did she earn in profits each year?
Answer:
Profit earn 1st year = $102,300.26
Profit earn 2nd year = $511,501.3
Step-by-step explanation:
Given:
Total profit earn = $613801.5599999999 = $613801.56
Find:
Profit earn each year
Computation:
Assume,
Profit earn 1st year = x
Profit earn 2nd year = 5x
Total profit earn = Profit earn 1st year + Profit earn 2nd year
x + 5x = 613,801.56
6x = 613,801.56
x = 102,300.26
Profit earn 1st year = $102,300.26
Profit earn 2nd year = 5x = 5(102,300.26)
Profit earn 2nd year = $511,501.3
If SF = 5x + 2, SK = 27, and KF = 3x - 1,
find KF.
Answer:
KF = 35
Step-by-step explanation:
Since it's a line with K in the middle, we know that the distance SF is the same as SK + KF.
(Start at S, first go to K, then continue to F. You've traveled the same distance as from S to F.)
SF = SK + KF
Let's put in the values we got.
5x + 2 = 27 + (3x -1)
Opening the parenthesis.
5x + 2 = 27 + 3x - 1
5x + 2 = 26 + 3x
Now let's subtract 3x from both sides.
2x + 2 = 26
Now, subtract 2 from both sides.
2x = 24
If we divide by 2...
x = 12
We know that...
KF = 3x -1
Since x is 12, let's put that in.
KF = 3 * 12 - 1 = 36 - 1 = 35
Answer: KF is 35 !
19. Charlene Levington operates an oil change and tune-up service. She charges $33.95 per oil change. Tune-up is $72.50 for a four- cylinder engine, $82.50 for a six-cylinder engine, and $92.50 for an eight-cylinder engine. What are the charges for a week in which Charlene's facility did 35 oil changes and tuned 5 four-cylinder engines, 7 six-cylinder engines, and 2 eight-cylinder engines?
$2,240.75
Step-by-step explanation:
just multiply each tune up price by the amount she worked on within that week and add them all up
The charges for the week, including 35 oil changes and tune-ups for 5 four-cylinder engines, 7 six-cylinder engines, and 2 eight-cylinder engines, amount to $2308.25.
To calculate the charges for the week, we need to find the total cost for both oil changes and tune-ups.
Charges for Oil Changes:
Charlene did 35 oil changes, and each oil change costs $33.95. So the total charges for oil changes can be calculated as follows:
Total charges for oil changes = Number of oil changes * Cost per oil change
Total charges for oil changes = 35 * $33.95
Total charges for oil changes = $1183.25
Charges for Tune-ups:
For the tune-ups, she serviced 5 four-cylinder engines, 7 six-cylinder engines, and 2 eight-cylinder engines. Let's calculate the total charges for each type of engine and then add them together.
Total charges for four-cylinder engine tune-ups = 5 * $72.50 = $362.50
Total charges for six-cylinder engine tune-ups = 7 * $82.50 = $577.50
Total charges for eight-cylinder engine tune-ups = 2 * $92.50 = $185.00
Total charges for all tune-ups = $362.50 + $577.50 + $185.00 = $1125.00
Total Charges for the Week:
Now, let's find the total charges for the entire week by adding the charges for oil changes and tune-ups:
Total charges for the week = Total charges for oil changes + Total charges for all tune-ups
Total charges for the week = $1183.25 + $1125.00 = $2308.25
The charges for the week, including 35 oil changes and tune-ups for 5 four-cylinder engines, 7 six-cylinder engines, and 2 eight-cylinder engines, amount to $2308.25.
