Tucker was asked to solve the equation 5x + 3 = 6x + 1. He did not know if his first step should be to add 5 negative x-tiles, or 1 negative unit tile, to both sides. What advice would you give Tucker to help him decide on his first step? Explain.
Answer: First Subtract 5x from both sides. Then subtract 1 from both sides.
Step-by-step explanation: To solve an equation, get all the variables (x, in this example) on one side and all the constants (numbers alone) on the other side of the equation.
The thing to remember about solving an equation is to keep it balanced. Do the same thing on both sides.
When possible, subtract smaller numbers from higher numbers.
5x + 3 = 6x + 1
5x -5x + 3= 6x - 5x + 1
5x-5x =0 on the left side so they "cancel" On the right, 6x-5x = x
3 = x + 1
3 -1 = x +1 -1
On the right 1-1 = 0 So the 1's "cancel" On the left 3-1 = 2
2 = x Rewrite as x = 2 to tell the solution

Describe why alternate interior angles are not always congruent?
Answer:
The Alternate Interior Angles Theorem states that, when two parallel lines are cut by a transversal , the resulting alternate interior angles are congruent .
Answer:
Alternate angles are always interior so in that case they will never meet up or join each other. hope this helps !
Step-by-step explanation:
in 2005 8.1 x 10^10 text messages were sent in the united states. in 2010, the number of annual text messages has risen to 1,810,000,000,000. about how many times as great was the number of text messages in 2010 than 2005?
22.345679 times greater.
10^10 = 10 zeros. 10,000,000,000.
10 billion * 8.1 = 81 billion.
1.18 trillion / 81 billion = 22.345679

After learning how to fly, Wendy reduced her daily commute time by 75%. Previously, her commute took m minutes.
Which of the following expressions could represent Wendy's commute time, in minutes, after she learned how to fly?
Choose 2 answers:
A 0.25m
B [tex]\frac{1}{4} m[/tex]
C 1.75m
D [tex]\frac{3}{4} m[/tex]
E 0.75m
Answer: Since she reduced her daily commute time by 75%, her time now is 25% of her original. Thus, you have 0.25m or 25m%.

Which of the following is NOT a true statement about the angles shown below?
Answer:
He knows this because if the angles are added together the have to equal 180 degrees because a line equals 180 and lines make up a triangle
Step-by-step explanation:
But the answer is A because x cannot equal 30 because it askes the angles not x so AHD is 30 also you can tell by looking that its not that big.

The dimensions of a rectangular dining room are 18 feet by 16 feet. If a scale factor of One-fourth is used to make a scale model of the dining room, what is the area of the dining room in the scale model?
18 square feet
36 square feet
48 square feet
72 square feet
Given -
The dimensions of a rectangular dining room are 18 feet by 16 feet. i.e, length (l) = 18 feet and breadth (b) = 16 feetScale factor of One-fourth is used to make a scale model of the dining room.To find -
the area of the dining room in the scale model (A)Solution -
As we know, the area of rectangle = length of the rectangle × breadth of the rectangle
To state the dimensions of the scale model we will multiply 1/4 with the already given dimensions of a rectangular dining room. Hence, dimensions of scale model is 18/4 by 16/4.
Now,
Area = length × breadth
Area = 18/4 × 16/4 square feet
Area = 18 square feet
Therefore, the area of the dining room in the scale model (A) is 18 square feet.
Answer:
18 square feet

Factors of 15: 1, 3, 5, 15
Factors of 20: 1, 2, 4, 5, 10, 20
What is the greatest common factor (GCF) of 15 and 20?
A. 5
B. 15
C. 1
D. 20
Answer:
A
Step-by-step explanation:
Answer:
A. 5
Step-by-step explanation:
It is A. 5 because if you look at the factors of 15 and 20, there are two common factos in both of them. 1 and 5, but the questions is asking for the greatest common factor of 15 and 20. 5 is greater than 1, so 5 is the greatest common factor, making A the answer.

can someone plss help me? Asap i still don't get the hang of Scale Factors
1. If the scale factor between the original and the image is 4, how many times larger is the perimeter of the image than the original?
2. If the scale factor between the original and the image is 0.5, how many times is the perimeter of the image than the original?
3.The perimeter of an original figure is 14. If the image has a scale factor of 6 from the original, what is the perimeter of the image?
4.The perimeter of an original figure is 64. If the image has a scale factor of 0.25 from the original, what is the perimeter of the image?
Problem 1
Answer: New perimeter is 4 times larger than the original
----------
Explanation:
This is because we are multiplying each side by 4 to make each side 4 times larger than the original.
Let's say we had a triangle with side lengths 1,2,3
The perimeter would be 1+2+3 = 6
Now multiply each side by 4
4*1 = 4
4*2 = 8
4*3 = 12
Then add up those new side lengths: 4+8+12 = 24
We see that 24 is exactly 4 times larger than 6
In more general terms, say the triangle has side lengths x y and z
The old perimeter is simply x+y+z
The new perimeter is 4x+4y+4z = 4(x+y+z) = 4*(original perimeter)
==========================================
Problem 2
Answer: New perimeter is 0.5 times larger than the old perimeter
In other words, the new perimeter is half as large
----------
Explanation:
The same idea applies as in problem 1. The only difference is that we're multiplying each side by 0.5 now
1/2 = 0.5
==========================================
Problem 3
Answer: 84
----------
Explanation:
We're using the same idea as the other problems above.
new perimeter = (scale factor)*(old perimeter)
new perimeter = (6)*(14)
new perimeter = 84
==========================================
Problem 4
Answer: 16
----------
Explanation:
Same idea as before
new perimeter = (scale factor)*(old perimeter)
new perimeter = (0.25)*(64)
new perimeter = 16
As you can see, if the scale factor is larger than 1, then the new perimeter will be larger. If the scale factor is smaller than 1, but still positive, then the new perimeter will be smaller.
Answer: The scale Factor is the number that you Multiply the Original Lengths by to get the new lengths.
1.) The new length is 4 times the original. 4× L
2.) The new length is 0.5 times the original. 0.5× L
3.) 84. 6×14 = 84
4.) 16. 64× 0.25 = 16
Step-by-step explanation:
For lines --- like sides, perimeter, and distance, Multiply the original number by the Scale Factor to get the new number. Or Divide the New number by the Scale Factor to get the Original.
(They ask that sometimes.)
__Also remember that length refers to lines__.
[ Area refers to Square Units. The Factor must also be squared. ]

Write a direct variation equation that relates 16 and 2
Answer: 16 = 2x
Step-by-step explanation:
The pattern for a direct variation equation is y = kx.
y is the "output" or result.
k is the "constant" a number that will remain the same.
x is the "unknown" or variable that will make the output correct once found.
Here, x = 8

find x and y if p || q and m3=(4x+6y),m5=86,and m6=(5x+6y)
Answer:
(8, 9)Step-by-step explanation:
3 and 5 are vertical angles and are equal as per definition of vertical angles
4x + 6y = 865 and 6 are supplementary angles and sum up to 180 as per definition of supplementary angles
5x + 6y + 86 = 180 ⇒ 5x + 6y = 94Comparing the two equations
6y = 86 - 4x and 6y = 94 - 5x86 - 4x = 94 - 5x5x - 4x = 94 - 86x = 8Finding y
6y = 86 - 8*46y = 86 - 326y = 54y = 9Answer
