Answer:
−27+7
Step-by-step explanation: First add 23x + 4x=27x
Then subtract 54x gives you -27x
You can't add a regular number with x's so your final answer is -27x+7

Does anyone have any ideas for multiplying 249 times 398 quickly and mentally? Everything online is too complex.
Answer:
So, the first solution is a calculator but sometime we don't have a calculator so, do
200 X 300 = A
40 X 90 = B
9 X 8 = C
then add just do multiplication from there like
A + B = D
D + C = E
Then your finally answer would be E
Hope that helps that's the way I do math quick in my head
(Btw the answer to 249 X 398 = 63,672 )
Mr townsend needs to make 13 pairs of butterfly for customers for a play. Each pair of wings is made with 3/4 yard of fabric. The fabric costs $8 per yard.
You’ll apply properties of multiplication in the following steps to find the total cost of fabric.
1. Use multiplication to write an expression for the amount of fabric needed to make 13 pairs of wings.
2. Multiply the amount of fabric by the price per yard to find an expression for the total costs.
3. Use the associative and commutative properties to rearrange the terms in the expression to make it easier to calculate. Explain why the rearranged expression is easier to work with.
4. Simplify your expression to find the total costs. show your work

Precalculus, Matrix
Rearrange terms, Combine multiplied terms into a single fraction, distribute, Multiply all terms by the same value to eliminate fraction denominators, Multiply all terms by the same value to eliminate fraction denominators . Cancel multiplied terms that are in the denominator . Multiply the numbers . Add 4 to both sides of the equation . Simplify.
Divide both sides of the equation by the same term . Simplify
Answer:
z = -3/2
Step-by-step explanation:
Our goal here is to solve -1/3 (4+z)=-5/6 for z.
Begin by multiplying both sides by 6, to eliminate the fractions:
-2(4 + z) = -5
Isolate (4 + z) by dividing both sides by -2: 4 + z = 5/2
Finally, determine z by subtracting 4 from both sides: z = 5/2 - 8/2 = -3/2
z = -3/2
2. A passenger train travels at an average speed of 45 mph and it took the passengers 27
minutes (.45 hours)to get to their destination. How many miles did the train travel?

Answer: 2.5
Step-by-step explanation: to find the unit rate/slope we need to pick 2 points and subtract the y's and x's
i picked (2, 5) and (1, 2.5)
5 - 2.5 = 2.5
2 - 1 = 1
2.5/1 = 2.5
2.5 is the slope

An online media service offers video and music downloads. Each download of a song costs $1. Each download of a video costs 5 times as much as the song download. You have a credit of $70. How many songs can you purchase after buying 12 videos?
Answer:
You can purchase 10 songs after buying 12 videos.
Step-by-step explanation:
Step 1 - Find out how much downloading a video costs. If the cost of a video download is 5 times as much as a song download costs, and a song download is $1, then you'd have to multiply 5 x $1, which equals 5. So downloading a video costs $5.
Step 2 - Find how much it costs to buy 12 videos by multiplying the cost of 1 video to how many you bought, 12. We already found out 1 video costs $5, so that would 12 x $5, which equals $60. That means those 12 video downloads costed you $60 dollars.
Step 3 - Find out how many songs you can buy with your remaining credit. If you already payed $60 dollars worth of videos, then you only have $10 dollars left to spend because $70 - $60 is $10. So if every song costs $1 dollar, then you'd be able to purchase 10 more songs until you reach your credit, $70 dollars.

The question is down below and I would really appreciate the help!
Answer:
y = 3x
Step-by-step explanation:
from the table slope or rate of change is
m = 6 - 0 / 2 - 0 = 6/2 = 3
m = 12 - 6 / 4 - 2 = 6/2 = 3
m = 18 - 12 / 6 - 4 = 6/2 = 3
so m = 3
y = mx + c
c is y intercept --> y value when x is 0
y = 0 = c
so line equation is y = 3x + 0
y = 3x
Answer:
B, or 3x.
Step-by-step explanation:
When looking at the x value (time), and the y value (distance), you can see that every time you multiply the x value by 3, you get the y value.
2 x 3 = 6
4 x 3 = 12
6 x 3 = 18
Therefore, your answer is 3x.

Done the first two but i dont know how to do the mean of it
To find mean:
1) Add up all data values to get the sum
2) Count the number of values in your data set
3) Divide the sum by the count
First we have to find all the data values. We do this by finding all of the peas, not just the information numbers of peas in a pod.
4 x 2 = 8
5 x 10 = 50
6 x 18 = 108
7 x 14 = 98
8 x 6 = 48
8 + 50 + 108 + 98 + 48 = 312 total number of peas
2 + 10 + 18 + 14 + 6 = 50
312 / 50 = 6.24 peas per pod
So in our example the mean number of peas in a pod is 6.24.
I hope this helps! :)
