A square has a side length of (x+3) centimeters. If the perimeter is 24 centimeters, what is the side length of the square? (Hint: to find
the perimeter of a square, you add up all the lengths of the sides).
A.Зcm
B.7cm
C. 9cm
D.14cm
Answer:
3 cm
Step-by-step explanation:
4(x + 3) = 24
4x + 12 = 24
4x = 12
x = 3 cm
**multiply by 4 because a square has 4 equal sides***
Answer:
3
Step-by-step explanation:
A square has 4 equal sides
so
4(x+3) = perimeter = 24
4x+12 = 24
4x = 12
x=3
Shawna and her best friend Keisha go shopping. The function p(x) = 3x4 + 2x3 − 4x2 + 21 represents how much money each girl spent based on the number of hours they were shopping. If Shawna and Keisha each go shopping for 2 hours, how much money did they spend together? $37 $69 $101 $138 Question 9(M
Answer:
$69
Step-by-step explanation:
Given the amount of money each girl spent based on the number of hours they were shopping modeled by the function p(x) = 3x4 + 2x3 − 4x2 + 21
To get how much they spend together if each go shopping for 2hours, we will substitute x = 2 into the given function as shown:
p(2) = 3(2)⁴ + 2(2)³ − 4(2)² + 21
p(2) = 3(16) + 2(8) − 4(4) + 21
p(2) = 48 + 16 − 16 + 21
p(2) = 48+21
p(2) = 69
Therefore they spend $69 together
Answer: 138$
Step-by-step explanation: 69$ is how much 1 girl spends. They both spend 138%$. Also, I took the test.

Manager Roberts watched from the dugout as her baseball team took the field. It was the ninth inning and her players were locked in a 9-9 tie with their opposers. Roberts studied the nine players she had positioned on the field: Simmons, Roe, Flow, Schmoe, Schmidt, Whitt, Kitt, Kent, and Kowalski
Her attention soon became absorbed by the curious fact that her nine players wore on their uniforms: 1,2,3,4,5,6,7,8, and 9. The more she looked at his players and their numbers, the more he noticed.

Jason ate 2/3 of the pizza. What part of the pizza is left? (split in 6)
Answer:
4
Step-by-step explanation:
2/3 * 6/1 = 12/3
12/3 = 4/1
The part of the pizza that is left = 2 from the 2/3 pizza eaten by Jason.
What are word problems in mathematics?Word problems in mathematics are the use of arithmetic and mathematical operations to solve problems real-life problems.
From the given information, Let us assume that the total amount of the pizza is 1.
If Jason ate 2/3 of the pizza, then the part of the pizza that is left is:
[tex]\mathbf{=(1 - \dfrac{2}{3})}[/tex]
[tex]\mathbf{=(\dfrac{3 -2}{3 })}[/tex]

Answer:
See Below
Step-by-step explanation:
Ok, so congruent means the same.
Using this knowledge, we can clearly see that the bottom pair are not congruent.
For the first pair, let compare the slopes and lengths of the line segments.
(If you have wax paper, you can trace A and see if it matches B)
GH <=> PQ = 2 blocks
LG <=> UP = 5/1 slope
KL <=> TU = 2 blocks
JK <=> ST = 1 block
IJ <=> RS = 1/1 slope
HI <=> QR =3 blocks
As you can see, all the corresponding side lengths/ slopes are the same.
This means the first pair are congruent.

Here is a table of the average distance and the variation in the distance for the five innermost planets in our solar system: Average Distance and Variation Planet Name Average Distance Variation Mercury 36.0 million miles 7.39 million miles Venus 67.2 million miles 0.43 million miles Earth 93.0 million miles 1.55 million miles Mars 142 million miles 13.2 million miles Jupiter 484 million miles 23.2 million miles "Average distance" means the mean distance that planet is from the sun over the course of its orbit, and "variation" means how far it varies from that mean. For example, if a planet had an average distance of 5 miles and a variation of one mile, it would have distances between 4 and 6 miles at different times. a) Write and solve an inequality to represent the range of distances that can occur between the Sun and one of the planets from the table (your choice). Show your steps/process. b) Why is this best represented as an inequality rather than an equation? Explain in at least 3 sentences.

Answer:
a) |e-93|≤1.55; 91.45 ≤ e ≤ 94.55
b) see below
Step-by-step explanation:
a) Let e represent the distance from the sun to the earth in millions of miles. The table tells us the average distance is 93.0 million miles, and the difference from that value can be as much as 1.55 million miles. The corresponding inequality is ...
|e-93.0| ≤ 1.55
We can solve this by rewriting it as a compound inequality.
-1.55 ≤ e -93.0 ≤ 1.55
91.45 ≤ e ≤ 94.55 . . . . . . add 93

b) An absolute value equation will give a finite number of particular values as its solution. The question asks for a range of values. An absolute value inequality is well-suited to providing a solution that is a range of values.

Mary owns a coffee shop. She charges $4.50 for a cup of coffee, and it costs her $1.25 to make each cup of coffee plus a $75 a day for other expenses. Write and solve an equation to determine how many cups of coffee, c, will Mary need to sell to break-even?
Answer:
Approximately 23 cups of coffee
Step-by-step explanation:
Break even = Fixed cost/Selling price - variable cost
Fixed cost = $75
Selling price = $4.50
Variable cost = $1.25
Break even = $75/$4.50 - $1.25
= 23.076923077
Approximately = 23
Therefore, Mary has to sell approximately 23 cups of coffee daily in order to break evem

help asappppp? i’m having trouble on wat the 1/4 point is
Answer:
(-14, 5.5)
Step-by-step explanation:
Perhaps the easiest way to find the 1/4 point is to find (x, y), then find the midpoint between that and M.
(x, y) = 2M -(13, 25) = 2(-5, 12) -(13, 25) = (-23, -1)
Then the 1/4 point is ...
((-23, -1) +M)/2 = ((-23, -1) +(-5, 12))/2 = (-28, 11)/2 = (-14, 5.5)
_____
If we call the end points A(x, y) and B(13, 25), then we know ...
M = (A+B)/2
A = 2M -B . . . . we'll need this in a bit
and the 1/4 point Q is such that ...
(Q -A)/(B -A) = 1/4
4Q -4A = B -A . . . . cross multipliy
Q = (B +3A)/4 = (B +3(2M -B))/4 = (6M -2B)/4 . . . . solve for Q
Q = (3M -B)/2 . . . . reduce the fractions
Q = (3(-5, 12) -(13, 25))/2 = (-28, 11)/2 = (-14, 5.5) . . . as above

Solve the inequality -2(4x-2)<-8x+4
Answer:
There are no solutions.
Step-by-step explanation:
−2(4x−2)<−8x+4
Step 1: Simplify both sides of the inequality.
−8x+4<−8x+4
Step 2: Add 8x to both sides.
−8x+4+8x<−8x+4+8x
4<4
Step 3: Subtract 4 from both sides.
4−4<4−4
0<0

Answer:
7. m<RST = 138°
8. m<MNP = 56°
9. m<WXZ = 130°
10. m<ABC = 118°
Step-by-step explanation:
7. m<RST = 138° (alternate exterior angles are congruent)
8. m<MNP = (a + 28)°
(a + 28)° = 2a° (alternate interior angles are congruent)
a + 28 = 2a
Collect like terms
28 = 2a - a
28 = a
m<MNP = (a + 28)°
Substitute a = 28
m<MNP = (28 + 28)° = 56°
9. m<WXZ = 5y°
5y = (2y + 78)° (alternate interior angles are congruent)
5y = 2y + 78
Collect like terms
5y - 2y = 78
3y = 78
Divide both sides by 3
y = 26
m<WXZ = 5y°
Plug in the value of y
m<WXZ = 5(26)
m<WXZ = 130°
10. m<ABC = (3n - 47)°
(3n - 47)° + (n + 7)° = 180° (same side interior angles are supplementary)
3n - 47 + n + 7 = 180
Collect like terms
4n - 40 = 180
Add 40 to both sides
4n = 180 + 40
4n = 220
Divide both sides by 4
4n/4 = 220/4
n = 55
m<ABC = (3n - 47)°
Plug in the value of n
m<ABC = 3(55) - 47 = 165 - 47
m<ABC = 118°
