Step-by-step explanation:
|14- c| = 15
=> 14 - c = 15 or 14 - c = -15
=> c = -1 or c = 29.
Cell phone plan a cost 70 per month but gives you a free 500 dollar phone plan b coat 50 dollors but has no phone. How long would it take them to reach the same proce
Answer:
Number of month = 25 month
Step-by-step explanation:
Given:
Plan A $70 per month and $500 phone cost
Plan B $50 per month No phone
Assume;
Number of month = x
So,
50x + 500 = 70x
20x = 500
x = 25
Number of month = 25 month
Write the equation of a line perpendicular to y =
3
x-3 and whose y-intercept is (0,12).
Answer:
y=-1/3x+12
Step-by-step explanation:
The slope of a line that is perpendicular to another is the negative reciprocal of the first. The slope of the line is 3 so the negative reciprocal will be -1/3.
Using the point-slope formula we can solve for the equation of a line with a slope of -1/3 and a point of (0,12).
The point slope formula is
y-y1=m(x-x1).
y-12=-1/3(x-0) -------------->Distribute: y-12=-1/3x ---------------> Isolate the y by moving the 12 to the other side. y=-1/3x+12

evaluate n²+5 when n=3
Answer:
14
Step-by-step explanation:
When you sqaure a number you multiply it by itself once so it would be (3x3) + 5. Rmemeber PEMDAS, so you multiply 3x3 first to get 9 and then you add 5 to get 14.
Tickets to the zoo cost $12 for adults and $8 for children. The school has a budget of $240 for the field trip. An equation representing the budget for the trip is: `240\ =\ 12x+8y`
Select all the true
If no adult chaperones were needed, 30 students could go to the zoo.
If ten students go to the zoo, then 15 adults can go.
If four more adults go to the zoo, that means there will be room for six fewer students.
If two more students go to the zoo, that means there will be room for three fewer adults.
If 16 adults go to the zoo, then 6 students can go.
Answer:
2 answers are true
Step-by-step explanation:
If no adult chaperones were needed, 30 students could go to the zoo. Is true
If 16 adults go to the zoo, then 6 students can go. Is also true

When 11 is subtracted from twice a number, the square root of the result is 4. Find the number.
Answer: I think 27/2
Explanation:
Let number = x:
√(2x - 11) = 4
Now to get x, we undo the square root by squaring both sides:
[√(2x - 11)]² = 4²
(2x - 11) = 16
2x = 27
x = 27 / 2

A racing car travels at a speed of 193 miles per hour.
Work out an estimate for the number of seconds the racing car travels in 10 miles.
Answer:
The estimate is 186.5 seconds.
Step-by-step explanation:
To calculate the estimate of the time the racing car will take to travel 10 miles, we have to first find the ratio of the original distance to the requested distance.
The number of seconds in an hour is [tex]60 \cdot 60[/tex] seconds, which equals to 3600 seconds.
[tex]\frac{193}{10} = \frac{3600}{x}[/tex]
[tex]19.3 = \frac{3600}{x}[/tex]
[tex]x = \frac{3600}{19.3}[/tex]
[tex]x \approx 186.5[/tex]
Hence, the estimate is 186.5 seconds.
Hope this helped!

I'll mark you brainliest if you give me the correct answer?
Answer and Step-by-step explanation:
We are asked to turn this fraction ([tex]\frac{9}{10}[/tex]) into an equivalent fraction, but with a denominator of 100.
[tex]\frac{9 <- Numerator}{10<-Denominator}[/tex]
All we have to do is multiply the numerator and denominator by 10, since 10 times 10 equals 100.
[tex]\frac{9}{10} * \frac{10}{10} = \frac{90}{100}[/tex]
The answer is:
[tex]\frac{90}{100}[/tex]

WHAT IS X???
1.2/0.96 = 3.0/x
Answer:
x= 2.4
Step-by-step explanation:
Answer:
2.4 or 12/5
Step-by-step explanation:
1.2/0.96=3/x
convert the decimal into a fraction---- 6/5 /0.96= 3/x
Simplify the complex fraction-----5/4 = 3/x
simplify the equation using cross-mulitpication----- 5 x = 12
divide both sides of the equation by 5--- x= 12/5
Check if the solution is in the defined range
Alternitive form:
x=2 2/5, x =2.4

An Auditorium has 29 rows, with 115 chairs in each rows. How many chairs does the auditorium have in all? Show your work
Answer:
3335 chairs
Step-by-step explanation:
To find the total number of chairs, multiply 29 by 115, since there are 29 rows that have 115 chairs:
29(115)
= 3335
So, the auditorium has 3335 chairs in all
Answer: 3335 Chairs
Work: So, the question already gave us how many seats are there per row, now we need to find out how many are there in 29 rows. You multiply 115 by 29 to find out how many seats are there, and you get 3335 chairs. I hope this helps you, and stay safe. :)
Find the circumference of a circle whose area

Answer:
12.41m
Step-by-step explanation:
Well, if we divide by the hypotenuse of the Pythagorean Theorem due to the angle created between the divisions on the scale between the 8th and 7th degree law of the Mathematical Institution of Nigeria, Ghana and Ethiopia (MINGE), then we get the result of 12.41.

Carlos is picking 6/384 apples. Mateo is picking oranges of 10. How much did Mateo pick?
Question might be incomplete or incorrect so we'd have to assume Mateo took apples
Answer:
5/189 apples
Step-by-step explanation:
If Carlos picks 6/384 apples then there must be 384 apples available to pick from. Amount of apples left after Carlos picks =384-6=378 apples
If Mateo picks 10 apples after Carlos then how much apples Mateo has taken would depend on the number of apples available, hence the fraction of apples Mateo has taken = 10/378
Reduce to lowest terms to get 5/189 apples

Ten years ago, the population at Lincoln High School was about 2,000 students. Since then, the population has increased by 25%.
What is the new population now?
Answer:
2,500 students
Step-by-step explanation:
If the population has increased by 25%, the total population of the school is now 125% of what it used to be. Then to figure it out, you find out 125% of 2000 which is 2,500 students!

Which set of ordered pairs does not represent a function? { ( − 3 , − 1 ) , ( 8 , − 1 ) , ( 0 , − 5 ) , ( − 9 , − 2 ) } {(−3,−1),(8,−1),(0,−5),(−9,−2)} { ( 5 , 9 ) , ( − 3 , − 5 ) , ( 0 , 4 ) , ( − 9 , 9 ) } {(5,9),(−3,−5),(0,4),(−9,9)} { ( 9 , 0 ) , ( − 5 , 4 ) , ( 5 , 0 ) , ( 6 , 3 ) } {(9,0),(−5,4),(5,0),(6,3)} { ( 2 , 8 ) , ( 2 , 1 ) , ( − 9 , − 5 ) , ( − 8 , 9 ) } {(2,8),(2,1),(−9,−5),(−8,9)} Submit Answer

[tex]\{(-3,-1),(8,-1),(0,-5),(-9,-2)\}[/tex]
[tex]\{(5,9),(-3,-5),(0,4),(-9,9)\}[/tex]
[tex]\{(9,0),(-5,4),(5,0),(6,3)\}[/tex]
[tex]\{(2,8),(2,1),(-9,-5),(-8,9)\}[/tex]
Required
Which is not a function
A function is of the form [tex](x,y)[/tex]
Assume a function is:
[tex]\{(x_1,y_1),(x_2,y_2),(x_3,y_3).....,(x_n,y_n)\}[/tex]
In simple terms:
For an ordered pair to be regarded as a function, no x value must be repeated
Analyzing the options:
1. [tex]\{(-3,-1),(8,-1),(0,-5),(-9,-2)\}[/tex]
This is a function because none of the x values (-3, 8, 0 and -9) appeared more than once
2. [tex]\{(5,9),(-3,-5),(0,4),(-9,9)\}[/tex]
This is a function because none of the x values (5, -3, 0 and -9) appeared more than once
3. [tex]\{(9,0),(-5,4),(5,0),(6,3)\}[/tex]
This is a function because none of the x values (9, -5, 5 and 6) appeared more than once
4. [tex]\{(2,8),(2,1),(-9,-5),(-8,9)\}[/tex]
This is not a function because one of the x values (2) appeared more than once.
i.e.
[tex](2,8)[/tex] and [tex](2,1)[/tex]

Mr. Gonzalez drove 30 miles in March. He drove 5 times as many miles in March as he did in January. He drove 2 times as many miles in February as he did in January. How many miles did Mr. Gonzalez drive in February?
Step-by-step explanation:
Given information :
Mr. Gonzalez drove 30 miles in March. In January, she drove 1/5 as much as in March.
30 ÷ 5 = 6 miles in January
in JanuaryShe drove 2 times as many miles in February as she did in January. In January, she drove 30 miles.
6 x 2 = 12 miles in February
