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

Price at which the share was bought = $56
The selling price of stock is below $30.
Therefore, the loss of carl would be greater than $56- $ 30 = $26
So, the size of loss of Carl any amount greater than $ 26.

Please help me find the answer for ABE ASAP plss!!
(Do not put links!!!)
Answer:
122
Step-by-step explanation:
The first thing to notice is that <EBC and <ABE form a straight line. This means they are a linear pair, also known as complementary. So, when they are added together they will equal 180 degrees. Therefore, to solve, set up and solve the algebraic equation, 180=58+x. When 58 is subtracted from both sides, you are left with x=122.

F(x)=400-4/5x find the function and intercepts
Answer:
The x-intercept is (500, 0); the y-intercept is (0, 400).
Step-by-step explanation:
F(x)=400-4/5x is already a function: a function of x.
To find the y-intercept, set x = 0 and calculate F(0):
F(0) = 400 - 0 = 400; the y-intercept is (0, 400).
To find the x-intercept, set F(x) = y = 0 and solve for x:
0 = F(x) = 400 - (4/5)x, or (4/5)x = 400. To isolate x, multiply both
sides by (5/4): x = (5/4)(400) = 500. The x-intercept is (500, 0).
Six friends attend a music concert and spend $27 per ticket. They each purchase a souvenir t-shirt. If the friends spend a total of $231, how much does each souvenir t-shirt cost
Answer:
11.50
Step-by-step explanation:
6x27=162
231+-162=69
69 divided by 6 is 11.5
11.5=11.50
11.50 is your answer
Answer:
$11.50.
Step-by-step explanation:
If there are 6 friends, and every ticket costs $27, then we need to multiply.
6 x 27 = 162.
Then, we subtract the cost of the tickets so we can find the total cost of the souvenir t-shirts.
231 - 162 = 69.
Since each of the 6 friends bought a souvenir t-shirt, we divide the total cost by the number of people.
[tex]\frac{69}{6}[/tex] = 11.5.
So, each t-shirt costs $11.50.
Can someone please help me with this question
Please check this answer
Please tell me if it’s correct if it’s not please answer it correctly please
Step-by-step explanation:
Hey,
I'm sorry, this is not correct. For a reflection, all you have to do is count the number of points from that specific point to the line. So, for example, w is 6 units away from the line, in order to draw that, count 6 units and graph. It's pretty hard to explain, but remember the shape is being reflected, so the orientation must change. I suggest searching this up.
Let me know if you have any more questions and I'll be more than glad to help.

In the morning, the number of ducks at the reservoir was 80. By noon, the reservoir had 135 ducks. What was the percent of change in the number of ducks? Round your answer to the nearest whole percent.
Answer:
60 percent
Step-by-step explanation:
number of ducks in morning=80
ducks in after noon=135
for percentage
80/135=0.5925=0.60
0.60*100=60 percent
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]

firstly u can take the value of x=3 then put the value of x in equation..then u will get y = 0 so from this equation u get this(3,0)
then do same thing take value x = 6 and then u will get the value of y = -1 therefore u will get (6,-1)
Now plot these two points (3,0) and (6,-1) on graph..
Hope it helps u..!!
You are the owner of the biggest and newest roller coaster called the Gentle Giant. The roller coaster costs $6 to ride. The operator of the ride must pay $200 per day for the ride rental and $65 per day for a safety inspection. If you want to make a profit of at least $1,000 each day, what is the minimum number of people that must ride the roller coaster? Write an inequality that can be used to find the minimum number of people, , which must ride the roller coaster each day to make the daily profit.
Answer:
Inequality: 6r - 200 - 65 [tex]\geq[/tex] 1000 and minimum of 211 people
Step-by-step explanation:
Let r = rides
6r - 200 - 65 [tex]\geq[/tex] 1000
6r - 265 [tex]\geq[/tex] 1000
6r [tex]\geq[/tex] 1265
r [tex]\geq[/tex] 210 [tex]\frac{5}{6}[/tex]
Needs 211 people to make a profit of at least $1000
The value of Tonya's car is $21,000. The car's value depreciates at a rate of 15% per year.
Which function represents the value of the car after t years?
O f(t) = 1.15(21,000)
O f(t) = 21,000(1.15)
O f(t)21,000(0.85)
O f(t) = 0.85(21,000)
Answer:
f(t) = 0.85(21,000)
Step-by-step explanation:
100% - 15% = 85% 0r in decimal form 0.85
0.85 x the original pricen 21,000
Answer:
the answer for this question is: f(t)=21,000(0.85)^t
Step-by-step explanation:
well since its asking what function represents the value, you have to convert the 15 percent into a decimal. so when you put the equation together you can see its 0.85.

Find the median.
Answer:
70
Step-by-step explanation:
The median is the value that is directly in the middle of the data set.
Hope this helps :)
The median of the mathematics quiz of the nine students is M = 70
What is Median?The median is the value that's exactly in the middle of a data set when it is ordered. It's a measure of central tendency that separates the lowest 50% from the highest 50% of values. The steps for finding the median differ depending on whether you have an odd or an even number of data points
Arrange the data points from smallest to largest.
If the number of data points is odd, the median is the middle data point in the list.
If the number of data points is even, the median is the average of the two middle data points in the list.
Given data ,
To find the median of the scores, we need to first arrange them in order from smallest to largest:
54, 64, 68, 69, 70, 71, 77, 85, 89
Since there are nine scores, the median is the middle score when they are arranged in order.
In this case, the fifth score (70) is the middle score, so the median score is 70.
Hence , the median score for the math quiz is 70

ABC is isosceles.
m < a = 3x + 40 and m < c = x + 50
what is m < a ??
Answer:
55°Step-by-step explanation:
It is assumed the angles A and C are congruent:
3x + 40 = x + 503x - x = 50 - 402x = 10x = 5m∠A = 3*5 + 40 = 55°
Answer:
