Answer:
7a + b - 16c
Step-by-step explanation:
So we have
7a-3b+c-8c+4b-9c
When it comes to problem like these, you need to combine like terms.
There's only one 'a' number, so that one remains the same.
Next, we have -3b and 4b. (-3b+4b)= b
Finally, there's (c-8c-9c).
(-8c-9c)= -17c
Take that and add the positive 'c' to it.
(-17c+c)= -16c
Put it all together now to get:
7a + b - 16c
I hope that helped and helped you understand at least a little

help i mark brain thing
Answer:
It is D
Step-by-step explanation:
Within each coordinate it represents (x,y)
The x moves along the horizontal line and the Y moves along the vertical line.
For example: For (-5,5) move to the left 5 times, then move up 5 times.
A negative X goes to the left and a negative Y goes down.
A positive X moves to the right and a positive Y moves up.

A number cube has 6 different faces, numbered 1 to 6. All faces have an equal probability of being rolled. What is the probability of rolling a 5?
please no links or weird pictures!
Answer:
its a 1/6 chance
Step-by-step explanation:
each face has a 1/6 chance of being rolled since there are 6 faces
Answer:
Answer:
40.2 % to the nearest tenth.
Step-by-step explanation:
Probability( 6 on one roll = 1/6).
Probability (6 on first roll and NOT 6 on the next 5 rolls) = 1/6 * (5/6)^6
= 3125/46656
= 0.06698
Only 1 six rolled can happen in 6 different ways ( where the 6 is on the second, third roll etc.)
So the required probability is 0.06698 * 6 = 0.40188.

Grace and her brother need $400 to go to band camp. Their parents have agreed to help them earn money by paying them $25 each time they mow the lawn and $10 for each hour they babysit their younger brother. They will have to do a combination of both chores to earn the money.
Select the equation that represents the number of lawns they can mow, m, and hours they can babysit, b, to earn $400.
M. 10m+ 25b= 400
P. 10m− 25b= 400
R. 25m+ 10b= 400
S. 25m− 10b= 400
Answer:
25m + 10b = 400
Step-by-step explanation:
Total amount that can be earned = $ 400
Amount earned on mowing a lawn = $ 25
Amount earned per hour on babysitting = $10
Amount earned for mowing one lawn is $ 25, so amount earned for mowing m lawns will be $ 25m
Amount earned for one hour of babysitting is $ 10, so amount earned for babysitting for b hours will be $ 10b
Total amount earned = Amount earned from mowing m lawns + Amount earned from babysitting for b hours
Using the values from above, we can set up the equation as:
400 = 25m + 10b
The center of a circle is at (5, –4). A point on the circle is located at (12, –4). What is the approximate circumference of the circle?
Answer:
43.98 approximately
Step-by-step explanation:
radius = [tex]\sqrt{ (5 - 12)^{2} + (-4+4)^{2} }[/tex]
= [tex]\sqrt{(-7)^{2} + 0^{2} }[/tex]
= [tex]\sqrt{49} = 7[/tex]
diameter = 14
Circumference = diameter x pi
= 14π = 43.98 approximately

Answer:
50
Step-by-step explanation:
70+60 =130
180-130 = 50 degrees
Answer: 50
Step-by-step explanation: Every triangle is 180 degrees so add the 60 and the 70 to get 130. 180-130=50. So 50 is your answer.
Solving a word problem involving a sum and another basic relationship using a system of linear equations.
At a basketball game, a vender sold a combined total of 130 sodas and hot dogs. The number of hot dogs sold was 44 less than the number of sodas sold. Find the number of sodas sold and the number of hot dogs sold.
Number of sodas sold:
Number of hot dogs sold:
sodas: 130
hot dogs: 86
there is 130 sodas sold if you subtract 44 from 130 you get how many hotdogs

Answer: The probability of picking a pen from the first box and a crayon from the second box is 5/8 x 1/4 = 5/32.
Step-by-step explanation:
What is the probability of choosing a pen from the first box? It is 5/8.
What is the probability of selecting a crayon from the second box? It is 3/12 = 1/4.
The probability of picking a pen from the first box and a crayon from the second box is 5/8 x 1/4 = 5/32.
Brianne's town is building a pool based on a scale drawing that is 20 centimeters by 10 centimeters and uses the scale 1 cm:250 cm. What is the area of the pool in square meters? Enter the area of the pool in the box.
Answer:
[tex]A=1250m^2[/tex]
Step-by-step explanation:
From the question we are told that
Dimension of drawing
20 centimetres by 10 centimetres
Scale of drawing
1 cm:250 cm
Generally the the Main dimension of the pool is mathematically given as
[tex]L=length\ of\ scaled\ pool*250 cm\\B=length\ of\ scaled\ pool*250 cm\\L=20*250=5000 cm=50m\\B=10*250=2500 cm=25m[/tex]
Therefore Area Aof main pool is mathematically given as
[tex]A=50m*25m=1250 m^2[/tex]
[tex]A=1250m^2[/tex]

Juan decided to start savings for college. He deposited $500 into an account which earns 4% simple annual interest. At the end of each year, he will add $250 to this account. How much will he have in his account after the end of three years?
a
$550
b
$770
c
$1,050.80
d
$1,342.83
Answer
I am getting a different answer The reason being the first year we calculating the 4% of the initial amount of the $500 towards the end of the year if he deposits the 250 the second year he gets to have a 4% interest of the 750 in total If he deposits the 250 in the 3rd he gets to have a 4% of 1000 So if you actually calculate that and get the total of all the amount which is 1,000 plus the percentages of all that you get what I've shared
9514 1404 393
Answer:
d $1342.83
Step-by-step explanation:
At the end of the first year, the account balance will be $500 plus 4% interest on that amount, plus the $250 deposited at the end of the year:
$500(1.04) +250 = $770
At the end of the second year, the account balance will be $770 plus 4% interest on that amount, plus the $250 deposited at the end of the year:
$770(1.04) +250 = $1050.80
At the end of the third year, the account balance will be $1050.80 plus 4% interest on that amount, plus the $250 deposited at the end of the year:
$1050.80(1.04) +250 = $1342.83
_____
Additional comment
You can make an appropriate guess by realizing the total of the deposits is ...
$500 + 3×250 = $1250
Adding interest to that will increase the amount. The only answer choice greater than $1250 is $1342.83.

If the pointer in the figure is spun twice, find the probability that the pointer lands on yellow (Y) both spins.
Answer:
0.25
Step-by-step explanation:
Well assuming the result of the spin is uniformely random, the yellow area will come up 1/2 of the time (because it takes up 1/2 of the figure).
If it needs to land on yellow both times in two spins, we can take it step by step.
The probability it lands on yellow after the first spin is 0.5
The probability it lands on yellow and then lands on yellow again is 0.5 * 0.5 = 0.25
Think of both spins as 50% yellow, 50% non-yellow
We have 4 options
yellow, yellow
yellow, non-yellow
non-yellow, yellow
non-yellow, non-yellow
Each option is equally probable, so the probability of "yellow, yellow" is 0.25
