Answer:
7 / 6
Step-by-step explanation:
( 2x + 6 ) / 5 = 4x - 3
2x + 6 = 5 ( 4x - 3 )
2x + 6 = 20x - 15
20x - 15 = 2x + 6
20x - 2x = 6 + 15
18x = 21
x = 21 / 18
21 = 7 * 3
18 = 6 * 3
x = 21 / 18
= ( 7 * 3 ) / ( 6 * 3 )
x = 7 / 6
Hence proved.

After watching Donald Duck in Mathmagic Land, please type out three things that you learned from the video. Did you like the video? Why or why not? Please answer all parts to the question
Answers
Answer:
Hope this helps
Step-by-step explanation:
Mathmagic Land had taught me more about math that I never knew before. I learned that everything can be involved with math. It all starts at the Pythagoreans which were the Greek. An example of how math is used today, is by playing billiards.
In billiards, you have to have a good technique of how your going to hit the ball, (good angles,) and you have to have a precise calculation of the angle your going to hit it at.I also learned when you cut shapes like a sphere, it just makes more and more shapes.
This is what I learned watching the Mathmagic Land Video.
Yes, Donald Duck in Mathmagic Land taught me alot of things I did not know before.

prove that 5^(2n - 1) is divisible by 8
Answers
Answer:
Step-by-step explanation:
Prove that 52n − 1 is divisible by 8 for all n ∈ N.
Solution
To prove by induction, we must
1. Show it is true for n = 1
2. Assume true for n and prove it is true for n + 1.
Let P(n) be the statement 52n − 1 is divisible by 8.
When n = 1, 52 − 1 = 24, which is divisible by 8.
This proves P(1).
Suppose that P(n) is true, i.e., 52n − 1 is divisible by 8.
Then 52(n+1) − 1 = 52
· 5
2n − 1 = 52
(52n − 1) + (52 − 1).
Note that 52n −1 is divisible by 8 using P(n) and also 52 −1 = 24 is divisible
by 8. Thus we have proved that P(n + 1) is true.
We conclude that P(n) is true for all n ∈ N.

what is the slope of a line b perpendicular to line a with equation y=7x-9
Answers
Answer:
The slope of line b would be -1/7.
Step-by-step explanation:
This happens because if you have the slope of any line and are trying to find the perpendicular line to said line, the slope of the perpendicular line will always be the opposite reciprocal of the original slope.
Then, all you need to do is find some points and graph the lines.

Answers
400 minus 60 is 384
so The bat was sold for 384 but 384 in currency is 329.94
Answer:
$340.00
Step-by-step explanation:
What I like to do first is find 10% of the number.
So 10% of 400 would be $40.
Then find half (5%) of the 10% ($40), which would be $20.
Add the $40 + $20 to get $60.
Then take $400 and subtract $60,
which gives you $340.00

Answers
Answer: Slope of the line formed by the data is -3.
m=-3 for y=mx+b.
Step-by-step explanation: The slope is the change in y (the rise) divided by the change in x (the run) between two points on the line. I'll pick 2 points: (-4,17) and (9,-22). Any two points will work, if it is a straight line. For these points, y, the rise, changes from 17 to -22, for a net change of (-22 - 17) = -39 for y. x, the run, goes from -4 to 9, for a change in x of (9 - (-4)) = 13.
The rise(y) over the run(x) for these points is thus (-39/13) = -3
The slope is -3

Which of the following rational number between 3/7 and 7/8 ?
13/56
19/56
27/56
53/56
Answers
Answer:
Step-by-step explanation:
There are two ways to do this. You could use your calculator to find out the decimal numbers that are equivalent to the two given fractions. Then check which one of the givens falls between these two numbers. I wouldn't do it that way -- not when you are told that the answer has 56 as the denominator. So ...
The best way to do it is to change the two givens so that they have a denominator of 56
3/7 = 3*8/7*8 = 24 / 56
7*7 / 7*8 = 49 / 46
So you need a number that is between 49 and 24
There is only one 27 / 56
