Step-by-step explanation:

1) =========================

14 + (-12) = 14 - 12 = 2Option C)

2) =========================

7 - (-7) = 7 + 7 = 14Option D)

3) =========================

8 + (-12) = 8 - 12 = - 4- 4 + 4 = 0Option A)

5) =========================

22 - 27 + 10 = 5Option B)

Answer:

1.) C

2.) C

3.) A

5.) B

Step by-step explanation:

1.) because 14 is positive and the opposite of 12 is -12. So 14+-12=2!

2.) to get to 7 from -7 you would have to take 7 units to get there.

3.)Given that a football player caught the ball and made a gain of 8 yards on the first play. On the next play the team lost 12 yards.we are to find the number of yards needed to gain on the next play to get back to their original position.Let, x be the number of yards that the team had originally.On the next play, the team lost 12 yards, let 'k' be the number of yards  needed to gain on the next play to get back to their original position.Thus, the number of yards needed to gain on the next play to get back to their original position is 4.

5.) We have been given that on Monday morning the temperature was 38°F, but by the afternoon the temperature had risen 22°F. We are also told that on Tuesday morning the temperature had dropped 27°F since Monday afternoon.Since the temperature rose  by the Tuesday noon, so temperature by Tuesday noon will be 10 degrees greater than temperature by Tuesday morning.To find the number of degrees temperature is above or below 38°F on Tuesday at noon we will subtract 38°F from the temperature on Tuesday at noon. Since the difference between temperature is positive, therefore, the temperature on Tuesday at noon was 5 above .

What property justifies step 4?
a. Commutative Property of Addition
c. Multiplication Property of Equality
b. Addition Property of Equality
d. Substitution

Answers

Answer:

Step-by-step explanation:

A.

Option A is correct. The property that justifies step 4 based on the calculation is the Commutative property of addition.

Equations are expressions separated by an equal sign.

Given the equation:

2(x-3) + 3x = 19

Expand the parenthesis using the distributive law

2x - 2(3) + 3x = 19

2x - 6 + 3x = 19

Collect the like terms

2x + 3x -6 = 19

Step 4

Since 2x+3x = 3x+2x = 5x (according to the commutative law), the expression becomes:

5x-6 = 19

Step 5

Add 6 to both sides

5x-6+6 = 19+6

5x = 25

x = 25/5

x = 5

Hence the property that justifies step 4 based on the calculation is the Commutative property of addition.

Answers

Answer: C.) $1,935.12

Step-by-step explanation:

Using the deferred annuity calculator :

Principal amount = 1140

Interest (r) = 26.78% = 0.2678

Period of payment = 2 years, compounded monthly, n = 24

Using the deferred annuity calculator ; Total balance = $1936.24

Hence, the closest cost in the option is $1,935.12

No matter how long they rent for, they have to pay at least 20. Any additional hour is 10. But since it says “part of an hour” that makes this really easy.
1) $30 (the first hour is 20, the second hour is 10 even though they didn’t use the full hour completely)
2)$30 (same situation as 1)

- Line B
- Line C
- I dont Know

Answers

Line c. Using rose over Tun 2/1 rising 2 on the graph and over one it is has the least about of slant

The line whose absolute value of the slope is least will be the slope which is close to being horizontal. Hence, line C is the answer.

An horizontal line has will have a slope value of 0. Hence, the steeper the slope, the greater the absolute value of the slope obtained.

This means that a line deviates more from being horizontal as the absolute value of the slope increases.

Therefore, the line with least absolute value would be the closest to being horizontal, hence, line C with an absolute value of 2.

A. Triangle, Circle,Square

B. Circle, Square

C. Rectangle,Circle

Circle, Circle, Triangle

Answers

The third pattern because you can divide 12 by the number of shapes in the sequence and start counting from the remainder.

In this case choice C has 5 shapes. 12/5 is 2, with a remainder of 2.

The second term in choice C is Circle, so choice C is the answer.

Of course, you can also list them all out.

If there is no remainder when you divide then the 12th term is the last term in the sequence.
