Answer:
children: 317
adults: 82
Step-by-step explanation:
x = children
y = adults
x + y = 399
125x + 250y = 60125
125x + 125y = 49875
125x + 250y = 60125
-125y = -10250
y = 82
x + y = 399
x + 82 = 399
x = 317
Answer:
82 adults 317 children
Step-by-step explanation:
c= children
a = adults
A) a+ c = 399
B) 1.25(c) + 2.50(a) = 601.25
Multiply the whole A) by -1.25
Add A) +B) (c will be eliminated since 1.25c -1.25c=0)
-1.25 c - 1.25a = -498.74
1.25 c+ 2.50 a = 601.25
1.25 a = 102.50
Divide both sides by 1.25:
a = 82 (82 adults)
399-82 = 317 (317 children)
317 ($1.25) = $396.25 Price for 317 children
82($2.50) = $205 Price for 82 adults
Total:
$ 396.25 + $205 = $ 601.25
317 + 82 = 399
c =

Hello . Please help me with theses Negative exponents please and thank you.
Answer:
So, to work with negative exponents you need to multiply like a positive exponent, and move the decimal over double the digits place each time.
Examples:
If it is 4 with an exponent of -2, then you will multiply 4 by 4 to get 16, and then move the decimal over double the amount of digits. There are two digits, so you will move the decimal over four digits.
So the answer to 4 with an exponent of -2 would be .0016.

edward deposited $7,500 into a savings account 5 years ago. The simple interest rate is 5%. How much money did earn in interest?
Answer:
Edward earned $1,875 in interest.
Step-by-step explanation:
The formula for simple interest is i = prt, where p is the principal, r is the interest rate as a decimal fraction, and t is the time in years.
Here, p = $7,500, r = 0.05 and t = 5 years, and so the interest earned was
i = ($7,500)(0.05)(5) = $1,875.
Edward earned $1,875 in interest.

Systems By Graphing - Solve All Correctly For a Thanks, 5-Stars, And A Brianliest!
Answer:
Step-by-step explanation:
Amari= Graph C and Solution is (-6,-2)
Bella= Graph A and Solution is (3,4)
Carl= Graph B and Solution is (0,-3)
0 solutions because the slopes are the same. The lines will never cross because they are at the exact same angle.
No, I do not agree with Joey because the lines have different slopes and will lead to the system cross which is the solution.
1st graph: y=2x-1 and y=7 solution #1= (4,7)
2nd graph: y=-2x-3 and y=1/2x solution #2= (-2,1)
3rd graph: y=x and y= -1/5+6 solution #3= (5,5)

Hope i helped!
1/4 of the pie was left on Thursday.
What is a fraction?
Fractions represent equal parts of a whole or a collection. Fraction of a whole is when we divide a whole into equal parts, each part is a fraction of the whole.
According to the given problem
On Monday Jeff makes a chocolate pie,
On Tuesday, he and his friends eat half of it, the remaining pie is, 1 - 1/2 = 1/2,
On Wednesday they eat one half of the remaining pie. i.e., they eat (1/2) ÷ 2 = 1/4 pie and the remaining pie is 1/4.
On Thursday, the remaining pie for Thursday is 1/4
Hence we can conclude that 1/4 of the pie was left on Thursday.

will get brainliest To solve the system of linear equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 by using the linear combination method, Henry decided that he should first multiply the first equation by –3 and then add the two equations together to eliminate the x-terms. When he did so, he also eliminated the y-terms and got the equation 0 = 0, so he thought that the system of equations must have an infinite number of solutions. To check his answer, he graphed the equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 with his graphing calculator, but he could only see one line. Why is this? because the system of equations actually has only one solution because the system of equations actually has no solution because the graphs of the two equations overlap each other because the graph of one of the equations does not exist
