At the same store, Peter bought 2 pairs of pants and 5 shirts for $61, and Jessica bought 3 pairs of pants and 4 shirts for $67. How much does 1 SHIRT cost?
Hey there!!
Given :
The total cost for 2 pairs of pants and 5 shirts is $61.
The total cost for 3 pairs of paints and 4 shirts is $67.
Let's take the cost for each pair of paints as 'p' and the cost for each shirt as 's'.
Now, let's get these into an equation.
Peter's equation :
... 2p + 5s = 61
Jessica's equation :
...3p + 4s = 67
......................................................................................................
2p + 5s = 61 --- (1)
3p + 4s = 67 --- (2)
Multiply the first equation with 3 and the second equation with 2.
6p + 15s = 183
6p + 8s = 134
Subtract both the equations -
... 7s = 49
Divide both sides with 7.
... s = 7
Hence, the cost of each shirt is $7.
Hope my answer helps!!
Look at the figure. What is another way of naming line m?
Answer:
Line AB.
Step-by-step explanation:
Since we know that a line is a set of continuous points and it extends in both directions infinitely.
We can name a line either by a single small case letter or by labeling endpoints.
We can see that point A and point B lies on line m. We can name line m as line AB.
Therefore, another name for line m is line AB.

A cell phone company charges $45 a month for phone service and $0.25 for each text message. Which equation can be used to find the total number of text messages sent in a month? How many text messages were sent if the monthly bill was $75?
We are given
A cell phone company charges $45 a month for phone service and
$0.25 for each text message
(a)
Let's assume
total number of messages sent on each month is x
total monthly bill is $ y
so, we can set up equation
[tex]y=45+0.25x[/tex]
now, we can solve for x
Subtract both sides by 45
[tex]y-45=45+0.25x-45[/tex]
[tex]y-45=0.25x[/tex]
[tex]x=\frac{y-45}{0.25}[/tex]

How is multiplying a whole number by a mixed number the same as multiplying two mixed numbers?
because you make them all improper fractions
Multiplying a whole number by a mixed number involves the same principle as multiplying two mixed numbers in maths. Both first require converting the numbers into improper fractions, then multiplying the numerators together, and the denominators together, and finally simplifying the result.
Explanation:In mathematics, multiplying a whole number by a mixed number is fundamentally the same as multiplying two mixed numbers because both processes follow the same principle. Let's break it down step by step: First, both whole numbers and mixed numbers can be converted into improper fractions. For example, if you are multiplying 3 (a whole number) by 2 1/2 (a mixed number), you would first convert them into improper fractions. So, 3 becomes 3/1, and 2 1/2 becomes 5/2.
Then, you would multiply the numerators (top numbers) together and the denominators (bottom numbers) together, i.e., (3 * 5)/(1 * 2) = 15/2. Then, you simplify the fraction if needed.
The same process applies when multiplying two mixed numbers, for example, 2 1/2 * 1 1/4. Convert them to improper fractions (5/2 * 5/4), then multiply the numerators and denominators and simplify the result. Thereby, the principles of multiplication and conversion of numbers apply identically in both scenarios.

THIS ISN'T A MULTIPLE CHOICE QUESTION
THIS ISN'T A MULTIPLE CHOICE QUESTION
(a), (b), and (c) are equations you need to solve, and then tell if it has an infinite number of solutions, one solution, or no solutions.
Please don't be blind and read it carefully! I've already wasted 120 points in the past 20 minutes.
Solve each given equation and show your work. Tell whether it has one solution, an infinite number of solutions, or no solutions, and identify each equation as an identity, a contradiction, or neither.
(a) 3x - 5 + x = 2x - 3 + 2 + 2x
(b) 4x + 5 - 6x = -x +3 -x +2
(c) 8x + 2 - 6 = 4x +8 +3x
Answer:
Step-by-step explanation:
Problem A
3x - 5 + x = 2x - 3 + 2 + 2x
Bring like terms close to each other so they can be combined on both the left and right sides.
3x + x - 5 = 2x+ 2x - 3 + 2 Combine like terms
4x - 5 = 4x - 1 Stop. Nothing more is going to work and give you anything but No Solution. You will wind up with - 5 = - 1 which is a contradiction.
Number of Solutions: None
Classification: Contradiction
Problem B
4x + 5 - 6x = -x + 3 - x + 2 Bring like terms close to each other so they can be combined on both the left and right sides.
4x - 6x + 5 = -x - x + 3 + 2
-2x + 5 = - 2x + 5 Stop!!!
This will give an infinite number of solutions. Suppose x = 200. Then you will get
-2*200 + 5 = -2 * 200 + 5
- 400 + 5 = - 400 + 5
- 395 = - 395 No matter what you use, the same thing will happen. The equation is an identity. Identities are really useful when you are checking equations. The left side should always come out to be the right side.
Number of Solutions: Infinite
Classication: Identity.
Problem C
8x + 2 - 6 = 4x +8 +3x Bring like terms close to each other so they can be combined on both the left and right sides.
8x + 2 - 6 = 4x + 3x + 8 Combine like terms.
8x - 4 = 7x + 8 Subtract 7x from both sides
8x - 7x - 4 = 7x - 7x + 8 Combine like terms
x - 4 = 8 Add 4 to both sides
x = 4 + 8
x = 12
Solutions: 1
Classification: Neither. But it is actually classified as a conditional equation if it has 1 legitimate solution.

|2*z - 9| = 1
How do I find z in this equation?
Let's solve your equation step-by-step.
|2z − 9| = 1
Solve Absolute Value.
|2z − 9| = 1
We know either 2z − 9 = 1 or 2z − 9 = −1
2z − 9 = 1 (1 is a possibility)
2z − 9 + 9 = 1 + 9 (Add 9 to both sides)
2z = 10
2z /2 = 10 /2 (Divide both sides by 2)
z=5
2z − 9 = −1 (Possibility 2)
2z − 9 + 9 = −1 + 9 (Add 9 to both sides)
2z = 8
2z /2 = 8 /2 (Divide both sides by 2)
z = 4
1
Two solutions were found :
z=5
z=4
Absolute Value Equation entered :
|2z-9|=1
Step by step solution :
Step 1 :
Rearrange this Absolute Value Equation
Absolute value equalitiy entered
|2z-9| = 1
Step 2 :
Clear the Absolute Value Bars
Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.
The Absolute Value term is |2z-9|
For the Negative case we'll use -(2z-9)
For the Positive case we'll use (2z-9)
Step 3 :
Solve the Negative Case
-(2z-9) = 1
Multiply
-2z+9 = 1
Rearrange and Add up
-2z = -8
Divide both sides by 2
-z = -4
Multiply both sides by (-1)
z = 4
Which is the solution for the Negative Case
Step 4 :
Solve the Positive Case
(2z-9) = 1
Rearrange and Add up
2z = 10
Divide both sides by 2
z = 5
Which is the solution for the Positive Case
Step 5 :
Wrap up the solution
z=4
z=5

A planter in the shape of a cube has a volume of 1000in3 is the area of the base of the cube greater than or less than 1 square foot?explain
The cube volume is 10x10x10 inch3, so the base area is 10 inch x10 inch. On the other hand, we know that 1 square foot = 1 foot x 1 foot = 12 inch x 12 inch, so that is *greater* than the cube base.
Answer:
area of the base of the cube is smaller than 1 square foot
Step-by-step explanation:
since the volume of the cube is 1000 in^3 then its side must be (1000)^{1/3}
which is equal to 10 in
now, we know that area of the base of the cube will have an square cross section area= side^2
there area of base of the cube = 10^2= 100 sq in
now 1 foot= 12 in
therefore, 1 square foot = 12*12 square in = 144 sq in
clearly, area of the base of the cube is smaller than 1 square foot.
hope you liked the explanation.

Answer: A) It will have the same measure as the original angle
Step-by-step explanation:
When reflected, the angle will be the same. Essentially, reflecting is just like using a mirror. When you reflect something, or look in the mirror, it is the same only flipped. For this problem here, that would be the case. You are simply flipping the angle over the y-axis, therefore everything stays the same except the direction it faces.
