51% of the tickets sold at a school carnival were early-admission tickets. If the school sold 100 tickets in all, how many early-admission tickets did it sell?
Answer:
51 were the total number of the tickets sold at a school carnival were early-admission tickets.
Step-by-step explanation:
Total number of tickets sold by = 100
Let [tex]x[/tex] be the early-admission tickets sold by the school.
As 51% of the tickets sold at a school carnival were early-admission tickets.
so
[tex]x=\frac{51}{100}\times 100[/tex]
[tex]= 51[/tex]
Therefore, 51 were the total number of the tickets sold at a school carnival were early-admission tickets.

General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesAlgebra I
Solving systems of equations using substitution/eliminationSolving systems of equations by graphingStep-by-step explanation:
Step 1: Define systems
-20y - 7x = -14
10y - 2x = -4
Step 2: Rewrite systems
10y - 2x = -4
Subtract 10y on both sides: -2x = -10y - 4Divide -2 on both sides: x = 5y + 2Step 3: Redefine systems
-20y - 7x = -14
x = 5y + 2
Step 4: Solve for y
Substitution
Substitute in x: -20y - 7(5y + 2) = -14Distribute -7: -20y - 35y - 14 = -14Combine like terms: -55y - 14 = -14Add 14 on both sides: -55y = 0Divide -55 on both sides: y = 0Step 5: Solve for x
Define original equation: 10y - 2x = -4Substitute in y: 10(0) - 2x = -4Multiply: 0 - 2x - 4Simplify: -2x = -4Divide -2 on both sides: x = 2Step 6: Graph systems
Check solution set and systems.

Answer: C, 3158
Step-by-step explanation:
We are given the equation [tex]h(x) = -49x-125[/tex] and we are given the hint to substitute [tex]h(-67)[/tex] into the equation. So let's do that!
[tex]h(-67) = -49(-67)-125[/tex]
we substitute -67 for the values of x.
Then, we simplify.
[tex]= 3283 - 125[/tex]
[tex]h(x) =3158[/tex]
We then subtract the numbers we multiplied together to get out answer: 3158!

7. A hospital supply room only has a 70% hydrogen peroxide solution and a 90% hydro-
gen peroxide solution. How many liters of each should be mixed to obtain 50 liters
of a 85% solution? You must set up an equation and solve to receive credit.
Answer: 12.5 liters of 70% hydrogen peroxide solution and 37.5 liters of 90% hydrogen peroxide solution is required.
Step-by-step explanation:
Let x = Quantity of 70% hydrogen peroxide solution.
y = Quantity of 90% hydrogen peroxide solution.
To obtain: 50 liters of a 85% solution.
x+y =50 (i) (Total quantity of solution)
0.70x+0.50y=0.85(50) (Total quantity of hydrogen peroxide)
⇒ 0.70x+0.50y= 42.5 (ii)
Multiply 0.70 to (i) , we get
[tex]0.70x+0.70y=0.70(50)\\\\\Rightarrow\ 0.70x+0.70y=35\ \ \ \ (iii)[/tex]
Subtract (iii) from (ii), we get
[tex]0.20y=7.5\\\\\Rightarrow\ y=\dfrac{7.5}{0.20}\\\\\Rightarrow\ y=37.5[/tex]
Put value of y in (i) , we get
[tex]x+37.5=50\\\\\Rightarrow\ x=50-37.5\\\\\Rightarrow\ x= 12.5[/tex]
Hence, 12.5 liters of 70% hydrogen peroxide solution and 37.5 liters of 90% hydrogen peroxide solution is required.

The slope is negative because it's going left. If you count the spaces between the points, they go back 6 and up 1, making it -1/6
Pension = 12% of salary
Health Insurance = .3% of salary
Disability Insurance = 0.4% of salary
If Jacob's total contract with benefits is worth $48,814.20, what is his salary
Answer:
Salary = $43,313.40
Step-by-step explanation:
Let his salary be x.
Now we're told that;
Pension = 12% of his salary = 0.12x
Health Insurance = 0.3% of salary = 0.003x
Disability Insurance = 0.4% of salary = 0.004x
Since his total contract with benefits is worth $48,814.20
This means that;
x + 0.12x + 0.003x + 0.004x = 48814.2
1.127x = 48814.2
x = 48814.2/1.127
x = $43,313.40

Ashley is taking a road trip to visit her friend. She drives 87.5 miles before taking a break for lunch. After lunch, she finishes the trip without stopping again. The total distance to her friend's house is 200 miles. How far did Ashley drive after lunch? 112.5 miles 113.5 miles 123.5 miles I don't know.
Answer:
Answer 112.5 :)
Step-by-step explanation:
Based on the distance she was able to drive before lunch, Ashley was able to drive 112.5 miles
Ashley has a total of 200 miles to drive in order to get to her destination.
Out of that, she drove 87.5 miles and then rested. The number of miles to go is:
= Number of miles in total - Number of miles driven
= 200 - 87.5
= 112.5 miles
In conclusion, Ashley has driven 112.5 miles.

Describe what a positive slope means in a real world situation.
Answer:
A positive slope means that something is increasing. For example if there is a positive slope in the graph of position, that means the position is increasing, or there's a positive velocity. Another example, if the graph of velocity has positive slope, it means it is increasing or there's acceleration.
Hey so I need some help.
Is this the right answer? Or is it different? Thanks for any help <3
Answer: Yes, your answer would be correct.
Step-by-step explanation:
Reason:
y= -1/2(2) + 11 = 10
y = -1/2(4) + 11 = 9
y = -1/2(6) + 11 = 8
y = -1/2(8) + 11 = 7

buffy ate 100 fries in 5 minutes find her fry-eating rate in fries per minute
Answer:
20 fries per minute.
Step-by-step explanation:
If you express the number of fries per minute as 100/5 (as there are 5 minutes and 100 fries), assuming she ate at the same rate per minute, she had 20 fries per minute.
To check, multiply 20 by 5, in order to find out her fries per 5 minutes. It should be equal to 100.
Answer:
20 Fries per minute
Explanation:
20 fries x 1 minute = 100 fries in 5 min
