The length of a rectangle is 3 times the width the perimeter is 24ft find the dimensions of the rectangle
Step-by-step explanation:
let the unknown be x
length = 3x
width = x
Perimeter = 2 lengths + 2 widths
24 ft = 3x + 3x + x + x
24 ft = 8x
3 ft = x
dimensions = length × width
= 3(3) × 3
= 9 ft × 3 ft
if you wanna check,
24 ft = 3(3) + 3(3) + 3 + 3
24 ft = 24

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
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.

Find the distance between (4, -1) and (-2, -1). Round answer to the nearest tenth. *
Answer:
6
Step-by-step explanation:
You substitute the points into the distance formula. There aren't decimals in this answer, so I don't think you need to round to the nearest tenth. You can also check by plotting these points down on a graph.
(4, -1) (-2, -1)
The y coordinates are the same, you just need to count from -2 to 4. There are 2 steps before 0 and 4 steps after 0. So 2 + 4 is 6.
===========================================
Work Shown:
[tex]\text{Distance Formula}\\\\d = \sqrt{(x_1-x_2)^2 + (y_1-y_2)^2}\\\\d = \sqrt{(4-(-2))^2 + (-1-(-1))^2}\\\\d = \sqrt{(4+2)^2 + (-1+1)^2}\\\\d = \sqrt{(6)^2 + (0)^2}\\\\d = \sqrt{36}\\\\d = 6\\\\[/tex]
This value is exact. No rounding is needed.
-------------
A shortcut is to subtract the x coordinates and apply absolute value
So either |x1-x2| = |4-(-2)| = |4+2| = |6| = 6
Or |x2-x1| = |-2-4| = |-6| = 6
This shortcut only works because the y coordinates the same for both points.
On a graph, you can plot the two points and count the spaces between them. You should count out 6 spaces.
Which of the following is NOT a term used to describe slope?
Unit Rate

Answer:
Change in X over Change in Y
Step-by-step explanation:
The slope is represented by the change in Y over the change in X. Therefore, the third answer is not correct because the proportion is incorrect.

A basketball team played six games. In those games, the team won by 9 points, lost by 18, won by
8, won by 11, lost by 3, and won by 5. What was the mean difference in game scores over the six
games?
Answer: 2
Step-by-step explanation:
From the question, we are informed that a basketball team played six games and that in those games, the team won by 9 points, lost by 18, won by 8, won by 11, lost by 3, and won by 5.
Thee mean difference in game scores over the six games will be calculated as the summation of the scores divided by 6. This. Will be:
= [9 + (-18) + 8 + 11 + (-3) + 5]/6
= 12/6
= 2
The mean difference in game scores over the six
games is; 2
We are given the points by which a basketball team either won or lost 6 games.
- Won by 9 points = +9
- Lost by 18 points = -18
- Won by 8 points = +8
- Won by 11 points = +11
- Lost by 3 points = -3
- Won by 5 points = +5
Thus;
Mean difference of the 6 games is;
(+9 - 18 + 8 + 11 - 3 + 5)/6
>> 12/6
>> 2

The measures of ∠x and ∠y are equal. X is 3(m+2) and Y is 5m-58. Which is the value of m? A m=8 B m=26 C m=30 D m=32
Answer with step-by-step explanation:
M = 32
Step 1: Simplify both sides of the equation.
3(m+2)=5m−58
(3)(m)+(3)(2)=5m+−58(Distribute)
3m+6=5m+−58
3m+6=5m−58
Step 2: Subtract 5m from both sides.
3m+6−5m=5m−58−5m
−2m+6=−58
Step 3: Subtract 6 from both sides.
−2m+6−6=−58−6
−2m=−64
Step 4: Divide both sides by -2.
−2m/−2=−64/−2
m=32

In 2010, Joe bought 200 shares in the Nikon corporation for $22.07 per share. In 2016 he sold the shares for $15.11each.
a. What was Joe's capital loss?
b. Express Joe's capital loss as a percent, rounded to the nearest percent.
Answer: a. $1392
b. 31.5%
Step-by-step explanation:
a. What was Joe's capital loss?
Cost price = $22.07 × 200 = $4414
Selling price = $15.11 × 200 = $3022
Capital loss = $3022 - $4414
= -$1392
b. Express Joe's capital loss as a percent, rounded to the nearest percent.
= Capital loss/Cost price × 100
= 1392/4414 × 100
= 31.5%
Answer:
a. $1392
b. 31.5%
Step-by-step explanation:
a. What was Joe's capital loss?
Cost price = $22.07 × 200 = $4414
Selling price = $15.11 × 200 = $3022
Capital loss = $3022 - $4414
= -$1392
b. Express Joe's capital loss as a percent, rounded to the nearest percent.
= Capital loss/Cost price × 100
= 1392/4414 × 100
= 31.5%
