Answer 1

Answer: x = 40

Step-by-step explanation:

these two angles are vertical angles, they will equal each other

therefore, move numbers and variables to the opposite sides of the = sign to isolate the X

3x-10 = 2x + 30

   +10        +10           move the -10 by doing opposite

_____________

3x = 2x + 40

-2x   -2x                    move -2x by doing opposite

____________

x = 40

you can check your work by substituting 40 in place of x

3(40) - 10 = 2(40) +30

120-10 = 80 + 30

110 = 110

answer is correct

Answer 2

Answer:

x = 40

Step-by-step explanation:

The given angles are vertical angles, hence they are equal.

=============================================================

Solving for x :

⇒ 3x - 10 = 2x + 30

⇒ 3x - 2x = 30 + 10

x = 40

The product of 3 and 4 less than a number is 12.​

Answers

Answer:

x = 24

Step-by-step explanation:

x - (3 · 4) = 12

x - 12   =     12

  + 12      + 12

x = 24

Answer: x - (3 * 4) = 12, x = 24

Step-by-Step Explanation:

Let ‘x’ be the Unknown Number

Framing the Equation :-

=> x - (3 * 4) = 12

Solving the Equation :-

x - (3 * 4) = 12 (First Multiply 3 and 4)
x - (12) = 12 (Now, open the bracket)
x - 12 = 12 (Now, shift 2 to RHS)
x = 12 + 12 (12 becomes positive)
=> x = 24

Hence, the Unknown Number is 24.

Find slope and intercept of the line 3x - 2y - 7 = 0

Answers

The slope and intercept of the line 3x - 2y - 7 = 0 are -1.5 and -3.5 respectively

How to determine the slope and the intercept?

The equation of the line is given as:

3x- 2y - 7 = 0

Add 7 to both sides

3x - 2y = 7

Subtract 3x from both sides

-2y = -3x + 7

Divide both sides by -2

y = -1.5x -3.5

A linear equation is represented as:

y = mx  + c

Where m represents slope and c represents the intercept

By comparison;

m = -1.5 and c = -3.5

Hence, the slope and intercept of the line 3x - 2y - 7 = 0 are -1.5 and -3.5 respectively

How many hours must Miguel worked to receive $10,000 in total pay?

Answers

Using the linear equation, Miguel must work for 160 hours to receive $10,000 in total pay

Complete Question:

Miguel works as a technician in a company. If his hourly rate and flat pay are $50 and $2000, how many hours must Miguel worked to receive $10,000 in total pay?

How to determine the number of hours?

Let the number of hours be x and the total pay be y.

The equation that represents the total pay is represented as:

y = Rate * x + Base pay

From the question, we have:

Base pay = 2000

rate = 50.

So, we have:

10000 = 50 * x + 2000

Subtract 2000 from both sides

8000 = 50x

Divide both sides by 50

x = 160

Hence, Miguel must work for 160 hours

A grocery wants to make two kinds of coffee. One consoles for $1.40 pound, and the other cells for $2.95 a pound. He wants to makes a total of 21 pounds and sell it for $2.60 per pound. How many pounds of each kind should he use in the new mix? (round off the answers to the nearest hundredth)

Answers

Step-by-step explanation:

a lot of typos in the problem description.

I assume the price of the mix is 1:1 related to the prices of the individual types of coffee.

so, from what I understood we can define

x = pounds of the first type of coffee.

y = pounds of the second type of coffee.

x + y = 21 pounds

1.4x + 2.95y = 2.6(x + y) = 2.6×21 = $54.60

in the second equation we have to bring the given "$2.60 per pound" to the total price, which is $2.60 times the total amount of pounds (which is 21).

from the first equation we get

x = 21 - y

and that we use in the second equation

1.4×(21 - y) + 2.95y = 54.6

29.4 - 1.4y + 2.95y = 54.6

1.55y = 25.2

y = 25.2 / 1.55 = 16.25806452... ≈ 16.26 pounds

x = 21 - y = 4.741935484... ≈ 4.74 pounds

so, he should mix 4.74 pounds of the first (cheaper) type and 16.26 pounds of the second (expensive) type.
