Answer:

Equation: 15x= -75

x= -5

Step-by-step explanation:

15x= -75

Divide both sides by 15 to isolate the variable x

-75÷15= -5

Check

15× -5= -75

Hope this helps!

Answer:

The slope of the line represented by y = 5x is 5

Step-by-step explanation:

The form of the linear function is y = m x + b, where

To find the slope of a line from its equation compare the equation with the form of the linear function, then find the coefficient of x which is the slope of the line

∵ The equation of the line is y = 5x

→ Compare it with the form of the equation above

∵ The coefficient of x = 5

∴ m = 5

∴ The slope of the line represented by y = 5x is 5

5a+4a=180

a=20

5a=X

X=5×20

=100°

Answer:

100 degrees

Step-by-step explanation:

The opposite angle will always be the same. since the opposite is 5a, then x = 5a.  x is 5a, and 9a is 180 degrees so x=180(5/9), which is equal to 100 degrees.

Answer:

x=10

Step-by-step explanation:

(10-4)(10-8) = 12

(6)(2) =12

12 = 12

The required real number that satisfies the given expression is x=10, x= 2.

Given that,
To determined the real numbers x that satisfy the equation (x - 4)(x - 8) = 12

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,

(x - 4)(x - 8) = 12

x²-12x+32=12
x²-12x+20=0
(x - 10)(x -2) = 0

Thus, the required real number that satisfies the given expression is x=10, x= 2.

Answer:

The total cost of making the tank equals $2,082.48

Step-by-step explanation:

Giving the following information:

The tank requires 208 sq ft of material at $9.29 per square foot.

It also requires 4.5 hours of labor at $26.40 per hour plus 1.6 hours of labor at $19.60 per hour.

To calculate the total cost, we need to multiply the unitary variable cost by the total amounts:

Direct material= 9.29*208= $1,932.32

Direct labor= 4.5*26.4 + 1.6*19.6= $150.16

The total cost of making the tank equals $2,082.48
