Solve the equation for x:
-3(x + 4) + 5x = 24

Answers

Answer 1
Answer:

[tex]-3(x + 4) + 5x = 24\\\\-3x - 12 + 5x = 24\\\\2x - 12 = 24\\\\2x = 36\\\\x = 18[/tex]

The solution for x in this equation is 18.

Step-by-step explanation:

Step 1: Define

-3(x + 4) + 5x = 24

Step 2: Solve for x

Distribute -3:                    -3x - 12 + 5x = 24Combine like terms:        2x - 12 = 24Isolate x term:                  2x = 36Isolate x:                           x = 18

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x:                     -3(18 + 4) + 5(18) = 24Add:                                      -3(22) + 5(18) = 24Multiply:                                -66 + 90 = 24Add:                                      24 = 24

Here we see that 24 does indeed equal 24.

∴ x = 18 is the solution to the equation.

Evaluate the expression using mental math and the division algorithm.

Answers

Answer:

The given expression for the division is 23,529/23

Evaluating the expression using mental math gives;

23,529/23 = (23,000 + 230 + 230 + 23 × 3)/23 = 1000 + 10 + 10 + 3 = 1,023

Evaluating the expression using the division algorithm states as follows;

When an integer a is divided by another integer n, then we can find the numbers q and r such that a = b·q + r and a/b = q + r/b, where, b > 0, and 0 ≤ r ≤ b

Where;

q = The quotient

r = The reminder

Therefore, we have;

23,529 = 23×q + r

Given that 23 × 1029 = 25,529, we have

23,529 = 23 × 1029 + 0

Therefore, q = 1029, and r = 0

Question 3 (10 points)
(02.06 MC)

In the figure shown, line AB is parallel to line CD.

Part A: What is the measure of angle x? Show your work. (5 points)

Part B: Explain how you found the measure of angle x by identifying the angle relationships that you used along the transversal. (5 points)

AB and CD are parallel lines, and PQ and PR are transversals which intersect AB at P and CD at Q and R. Angle APQ is labeled as 65 degrees, angle QPR is equal to x, angle PRD is equal to 120 degrees.

Answers

Answer:

X = 53

X= 115 - 62

Step-by-step explanation:

Part A: 62 + X = 115

X= 115 - 62

X = 53

Part B:

APQ + QPR = PRD

Dont copy off of me because im not for sure  this is the right awnser            

The measure of angle x is 55.

And to get 55 you first need to find angle BPR.

So, what you would do is 180 - 120 and that equals 60.

So, this means that angle BPR is 60 degrees.

Ok, so now to find the angle of x.

You first need to do 65 + 60 + x =180.

Since we don't know the value of x, we do 65 + 60 and that gives us 125.

So, 180 - 125 = 55. 

So, X = 55.

Answers

Given :

Andrew has already played 32 minutes on his video game this morning and wants to play an additional 15 minutes on each of x games after school today.

To Find :

Which equation can be used to find y, the total minutes Andrew will play video games today.

Solution :

Number of minutes he play after school time, n = 15x .

Number of minutes already played, c = 32 .

So, total number of minutes he play games for today is :

y = n + c

y = 15x + 32

Therefore, equation which is useful to find number of minutes video game played per day is y = 15x + 32 .

Value of an algebraic expression depends on the values of its variables usually. The value of [tex]2x^2[/tex] for given condition is obtained to be 18

How to evaluate a given mathematical expression with variables if values of the variables are known?

You can simply replace those variables with the value you know of them and then operate on those values to get a final value. This is the result of that expression at those values of the considered variables.

For the given case, we are given that [tex]x - 1 =2[/tex]

By this, we can get the value of the variable 'x' as:

[tex]x - 1 = 2\\\text{Adding 1 on both the sides, we get}\\x = 3[/tex]

Now, putting 3, in place of x, in expression [tex]2x^2[/tex], we get:

[tex]2x^2 = 2 \times (3^2) = 2 \times 9 = 18\\[/tex]

( sign of multiplication is often hidden if there are non numeric symbols and numbers being multiplied are written together, thus, [tex]2x^2 = 2 \times x^2[/tex])

Thus, the value of [tex]2x^2[/tex] for given condition is obtained to be 18
