Step-by-step explanation:
Let's look at the statement.
7y = 14x and y = 2x does have infinitely many solutions. Why? Because the first equation can be rearranged to look like the second one. If you divide 7y and 14x by 7, you end up with y = 2x. Look familiar? This means the set of equations has infinitely many solutions.

Answer:
1. True
2. True
Step-by-step explanation:
So we are playing with variables here, lets look at 1.
5x + 9 = 29 if x = 4
This means that if x equals 4, would it make the equation true? Let's find out :
Substitute :
5(4) + 9 = 29
20 + 9 = 29
This is true, let's do the same for 2. :
7x - 8 = 13 if x = 3
7(3) - 8 = 13
21 - 8 = 13
This is also true.
How to solve (with steps)
3 ( x + 2 ) = 9 ( 6 - x )
Answer: x = 4
Step-by-step explanation:
Distribute the 3 and the 9
[tex]3(x+2)=9(6-x)\\3x+6=54-9x[/tex]
Add 9x to both sides
[tex]12x+6=54[/tex]
Subtract 6 on both sides and simplify
[tex]12x = 48\\x=4[/tex]
Answer:
x=4
Step-by-step explanation:
3 (x+2) = 9 (6-x)
3x + 6 = 54 - 9x
-6 = -6
3x = 48 - 9x
+9x +9x
12x = 48

Your digital camera has a 512 megabyte memory card. You take pictures at two resolutions, a low resolution requiring 4 megabytes of memory per photo and a high resolution requiring 8 megabytes of memory per photo. Write an equation to model the amount of each kind of photo you can take.
One possible answer is 8H + 4L = 512
=======================================================
Explanation:
H = number of high resolution photosL = number of low resolution photosH and L are placeholders for positive whole numbers, or 0 could replace either variable.
1 high resolution photo takes up 8 mb of space, so H of them take up 8H megabytes of space.
1 low resolution photo takes up 4 mb of space, so L of them take up 4L megabytes.
Overall, the two types of photos take up 8H+4L megabytes, which is equal to 512 since that's the max capacity. That leads to the equation 8H+4L = 512
----------------------------------
Extra info:
There are other ways to express the equation 8H+4L = 512. We could divide each part by 4 to get 2H+L = 128, but I think this equation loses its descriptive quality in a way. We no longer can see that each high resolution photo takes up 8 megabytes (instead we might mistakenly think only 2 megabytes are used per high resolution photo). A similar mistake may happen with the low resolution photos also.
The equation 2H+L = 128 can be rearranged into L = -2H+128 when solving for L.
4. Consider the mailbox shown below. It consists of a square prism for the main pole, a rectangular prism for the main box and half a cylinder for top portion. You are going to provide the dimensions for each of these parts. When you provide the dimensions, they must meet the following criteria:
Use these dimensions to determine the overall volume of the mailbox. This should include both the pole, main box and cylindrical top portion. If necessary, use 3.14 for π and round your answer to the nearest hundredths.
Answer:
Too many answers could be correct
Step-by-step explanation:
This one is hard because it will depend on what numbers you pick for each measurement.
-----------------------------------------------------------------------------
if a = 1, b = 2, c = 3, d = 4, and e = 5
find the volume for all the shapes
The post
V = lwh = (1)(1)(2) = 2
The bottom of the mailbox
V = lwh = (3)(4)(5) = 60
The top of the mailbox
V = πr²h = (3)(5)π = 15π = 48.2
Then add them all together:
2 + 60 + 48.2 = 110.2 is the total Volume

Determine if the expressions 100 divided by (25 divided by 5) and (100 divided by 25) divided by 5 are equivalent. If so, tell what property is applied. If not explain why.
Answer:
They aren't equivalent because when using P.E.M.D.A.S you solve what is in the parenthesis first. After you solve what is in the parenthesis the two expressions are completely different.
Step-by-step explanation:
100/(5)=20 (4)/5= .8
The requried results of the two expressions are different (20 and 0.8), the expressions are not equivalent.
Expression 1:
100 ÷ (25 ÷ 5)
Evaluate the expression inside the parentheses.
25 ÷ 5 = 5
Replace the expression inside the parentheses with its result:
100 ÷ 5
Perform the division:
100 ÷ 5 = 20
So, the result of Expression 1 is 20.
Expression 2:
(100 ÷ 25) ÷ 5
Evaluate the expression inside the first set of parentheses.
100 ÷ 25 = 4
Replace the expression inside the first set of parentheses with its result:
4 ÷ 5
Perform the division:
4 ÷ 5 = 0.8
So, the result of Expression 2 is 0.8.
Since the results of the two expressions are different (20 and 0.8), the expressions are not equivalent.
The reason why they are not equivalent is due to the order of operations. In Expression 1, we first divide 25 by 5 and then divide 100 by the result, while in Expression 2, we first divide 100 by 25 and then divide the result by 5.

Find the measure for < LQR
Answer:
A
Step-by-step explanation:
90 - 12b = - 3b + 63
- 12b + 3b = 63 - 90
- 9b = - 27
- b = - 27/9
-b = -3
b = 3
to find the measure of MQR:
-3*3 + 63 = 54°
to find the measure of LQR:
180 - 54 = 126° + 1 = 127°
====================================================
Work Shown:
Angles MQX and LQR are vertical angles, so they are equal to one another.
angle MQX = angle LQR
-4a+139 = 4a+123
-4a-4a = 123-139
-8a = -16
a = -16/(-8)
a = 2
Use this to find each angle
angle MQX = -4a+139 = -4*2+139 = 131angle LQR = 4a+123 = 4*2+123 = 131We get the same value 131 each time, so this confirms we have the correct value for 'a', and it confirms our answer for angle LQR.

Solve m1 and m2 In the diagram
Please help me solve Im so confused
Answer:
m<1=117
m<2=99
Step-by-step explanation:
Answer:
Angle 1 is 117 degrees.
Angle 2 is 59 degrees.
Step-by-step explanation:
Let angle 1 be x, and angle 2 be y.
By the exterior angle theorem, x + 21 = 138, so x = 138 - 21 = 117.
Again, by the exterior angle theorem, 79 + y = x = 138, so y = 138 - 79 = 59.
What is the equation of 35?
35 - X = 5
Simplifying
35 + -1X = 5
Solving
35 + -1X = 5
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '-35' to each side of the equation.
35 + -35 + -1X = 5 + -35
Combine like terms: 35 + -35 = 0
0 + -1X = 5 + -35
-1X = 5 + -35
Combine like terms: 5 + -35 = -30
-1X = -30
Divide each side by '-1'.
X = 30
Simplifying
X = 30

Step-by-step explanation:
Considering the answer choices:
Square
Regular pentagon
Parallelogram
Rectangle
Rhombus
It can't be a pentagon because it only has four sides.
Properties of the shapes:
Rectangle - quadrilateral with two sets of congruent opposite sides and four right angles.
Rhombus - quadrilateral with four congruent sides.
Square - quadrilaterals with all properties of rectangles and rhombi.
Parallelogram - rectangles, rhombi, and squares are parallelograms.
This shape satisfies the properties of a square, meaning it is also a rectangle, rhombus, and parallelogram.

x*6/5=4/9
6/5*4/9=x
4/9*6/5=x
Answer:
Select the third answer listed which states: 6/5 * 9/4
Step-by-step explanation:
To find how many of a quantity x are in another quantity y, we normally divide in the following fashion:
y divided by x = y ÷ x = y / x
Then we do the same here: 6/5 divided by 4/9 = 6/5 ÷ 4/9 = 6/5 * 9/4
