X + 7 = 23 middle school work

Answers

Answer:

X = 16

Step-by-step explanation:

23 - 7 = 16

Answer: 16

Step-by-step explanation:

23 - 7 = X

To find X we do the inverse of addition which is subtraction. The 7 cancels out and the 23 becomes a 16. We can even check our answer. 16 + 7 = 23

Use the model to solve for x.

Answer:

x = 7/3

Step-by-step explanation:

3x - 2 =5

Add 2 to each side

3x-2+2 = 5+2

3x = 7

Divide by 3

3x/3 = 7/3

x = 7/3

Answer:

x = 7/3

Step-by-step explanation:

So there's 3 x's, two -1s and 5 +1s.

3x + (2 * -1)  = (5 * 1)

Multiply 2 times -1 and 5 times 1.

3x - 2 = 5

Add 2 to both sides (to cancel out the minus 2.)

3x - 2 + 2 = 5 + 2

3x - 0 = 7

3x = 7

Now, divide both sides by 3 to get the x by itself (so you end up with x = something).

(3x)/3 = 7/3

3/3 simplifies to 1 so you end up with:

x = 7/3

An annual pass to a park costs $120. Use a percent model to find 25% of the full price of the annual pass. 25% of the full price is _____

Answers

Answer:

$30 is 25% of $120

25% of the full price of the annual pass is $30.

Given that, an annual pass to a park costs $120.

What is percentage?

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

We need to find 25% of the full price of the annual pass

Here, 25% of 120

= 25/100 × 120

= 0.25 × 120

= $30

Therefore, 25% of the full price of the annual pass is $30.

Step 2:

124° = x       Add

Answer:

x = 124°

Hope This Helps :)

Answer:

D) 124°

Step-by-step explanation:

Use the "Exterior Angle Theorem". The Exterior Angle Theorem states that the exterior angle's measurement is the sum of the two opposite interior angle's measurements.

In this case, it is given to you that the opposite angle's measurements are 72 and 52 degrees respectively. To solve, combine the two angles:

m∠x = 72 + 52

m∠x = 124°

m∠x = 124°, or D) 124° is your answer.

Liam is setting up folding chairs for a meeting. If he arranges the chairs in 6 rows of the same length, he has 11 chairs left over. If he arranges the chairs in 4 rows of that same length, he has 19 left over. How many chairs does Liam have?

Answers

Answer:

35 chairs in all

Step-by-step explanation:

each row has 4 chairs as if 4 rows has 19 extra chairs and 6 rows has 11 there are 8 chairs in 2 rows which means 4 chairs are in 1.

so take 4 (rows) x 4 (chairs) and get 16

16 + 19 (leftover) and get 35

Find the unit rate. Unit rate from chart

Answers

Answer:

I don't see a chart

Answer:

The unit rate is 15.

Explanation:

Time (hours)

6: $90            90/6 = 15

12: $180         180/12 = 15

18: $270        270/18 = 15

24: $ 360      360/24 = 15

You should find the unit rate by dividing y by x. I divided all of the y's by the x's and I got 15 for all of them, which means that the unit rate is 15.
