given the equation y=23x,whats the value of x if y=100
Answer: 4.3478 or 100/23
Step-by-step explanation:
Set the y values equal to each other since they are the same unknown (x). You end up with 100=23x, solve for x. Move the 23 over to the other side by using division. x=100/23. If you need it in decimal form, 100÷23=4.347826087
Answer:
4.3=x
Step-by-step explanation: y=23x
substitute the variable y to 100. Now the equation looks like this 100=23x. Your next step is to get get x by itself, so you would divide 23 on both sides. That would cancel out the 23 x. The only thing you have to do now is 100 divided by 23 and that would be 4.3 and a whole bunch of number so you just round it to the nearest tenth. You answer would be 4.3.
When attempting to do his homework, Mark incorrectly uses the addition property of equality below. Which
statement would correct Mark's error?

descending order. Enter exponents using the caret (^).
125x^3+343y^3
Answer:
(5x + 7y)(25x² - 35xy + 49y²)
Step-by-step explanation:
125x³ + 343y³ ← is a sum of cubes and factors in general as
a³ + b³ = (a + b)(a² - ab + b³) , thus
125x³ + 243y³
= (5x)³ + (7y)³
= (5x + 7y)((5x)² - 5x(7y) + (7y)² )
= (5x + 7y)(25x² - 35xy + 49y²)

Step-by-step explanation:
At a fast food restaurant, customers are asked if they want to “round up” their bill to the next highest dollar and donate the additional money to charity. The cashier is instructed to tell the customer that their bill is X dollars and Y cents. Assume that the values of Y are equally likely to be any value from 0 to 99 cents and that customers are equally likely to “round up” regardless of the amount of their bill. The density curve below models Y, the donation amount. (a) What is the shape of the distribution of donations? (b) What proportion of donations are at least 85 cents? (c) What percent of donations are between 30 and 40 cents?
Answer:
(a) 0.1414
(b) 0.1010
Step-by-step explanation:
(a)
The density curve is rectangular in shape.
This implies that the distribution of donations is Uniform.
(b)
Compute the probability of donations at least 85 cents as follows:
[tex]P(X\geq 85)=\int\limits^{99}_{85} {\frac{1}{99-0} \, dx[/tex]
[tex]=\frac{1}{99}\times [x]^{99}_{85}\\\\=\frac{99-85}{99}\\\\=0.1414\\\\[/tex]
Thus, the proportion of donations that are at least 85 cents is 0.1414.
(b)
Compute the probability of donations between 30 and 40 cents as follows:
[tex]P(30\leq X\leq 40)=\int\limits^{40}_{30} {\frac{1}{99-0}} \, dx[/tex]
[tex]=\frac{1}{99}\times [x]^{40}_{30}\\\\=\frac{40-30}{99}\\\\=0.1010[/tex]
Thus, the probability of donations between 30 and 40 cents is 0.1010.

Solve for x.
4−(2x+4)=5
A. x=32
B. x=−52
C. x=−10
D. x = 6
x = - 2.5
Step-by-step explanation:Hi there !
4 - (2x + 4) = 5
4 - 2x - 4 = 5
- 2x = 5
2x = - 5
x = - 5 : 2
x = - 2.5

ce is the angle bisector of dcb and m
Answer:
We are given that ray CE is an angle bisector of angle ACD. With this, we have the equation,
mACE = mECD
Next, we look at the choices
mECD = mECB > This not possible since ray CD is between the two angles
mACE = mACD > This is still not possible since ray CE is between the two angles
mACE = mDCB > This is possible since angles ACE, ECD and DCB are complementary angles.
mECD = mACD > This is not possible since ray CE is between the two rays
The answer is the third option
Step-by-step explanation:
Two friends race. The first friend gets a head start and runs at a steady rate of 0.20 miles per minute. The second friend waits 1 minute and then runs at a steady rate of 0.25 miles per minute. How long will it take for the second runner to catch up with the first?
Step-by-step explanation:
In this problem we are expected to solve for the time taken for the second person to meet with the first.
given that
first person's speed=0.2mph
let time taken be= x
we know that
velocity= distance/time
0.2=distance/x
distance=0.2x----1
second person's speed= 0.25mpm
time taken=x-1
we know that
velocity= distance/time
0.25=distance/x-1
distance=0.25(x-1)
distance=0.25x-0.25-----2
equating equation 1 and 2 we have
0.2x=0.25x-0.25
0.2x-0.25=-0.25
-0.05x=-0.25
divide both sides by -0.05 we have
x=-0.25/-0.05
x=5
we know that the second person's time is described by
=x-1
=5-1=4min
The second person will catch up after 4 minutes

A theater company charges $5.50 per ticket for people of all age groups. If c represents the total number of children who brought tickets and a represents the total number of adults who bought tickets, which expression best represents the total money earned by the company from the sale of tickets?
Answer:
[tex]5.50c+5.50a[/tex]
Step-by-step explanation:
Cost of 1 ticket = $5.50
Total number of children who brought tickets = c
Total number of adults who bought tickets = a
Amount earned from selling tickets to children = 5.50 c
Amount earned from selling tickets to adults = 5.50 a
Therefore,
Total money earned by the company from the sale of tickets = [tex]5.50c+5.50a[/tex]
