If x = 5 and y = 7, evaluate the following expression:
100 – 3(3y - 4x)
100 - 3(3 x 7 - 4 x 5)
Simplify
97(21 - 20)
Simplify
97(1)
Now, multiply.
97 x 1 = 97
So the answer to the equation above, is 97.
Jack has 24 game cards. He divides them between his brother, his sister, and himself in the ratio 2:1:5.
How many cards does each get?
Answer:
brother gets 6 cards
sister gets 3 cards
he gets 15 cards
Step-by-step explanation:
this can be rewritten as
2x + x + 5x = 24
combine like terms
8x = 24
divide both sides by 8
x = 24/8
x = 3
now, multiply x by each part of the ratio.
his brother = 2 * 3 = 6
his sister = 1 * 3 = 3
himself = 5 * 3 = 15

13. C.
14. A.
15. D.
Step-by-step explanation:
6. An algebraic equation is a mathematical sentence with an equal sign.
7. 3n + 6 = 66
8. Let n = Mayah's sister's age
let m = Mayah's age
let b = Mayah's brother's age
m = n - 2
b = n + 4
m + b + n = 26
⇒ n - 2 + n + 4 + n = 26
⇒ 3n + 2 = 26
9. 2n - 5
10. 2b - 6 = 16
11. n + 5 = 12
⇒ n = 7
12. c + 18 = 29
⇒ c = 29 - 18 = 11
13. h = 8 · 5 = 8 × 5 = 40
14. 453 + 364 + n = 1000
⇒ n = 1000 - 453 - 364
⇒ n = 183
15. 3n + 11 = 35
⇒ 3n = 35 - 11
⇒ n = 24 ÷ 3
⇒ n = 8
3 people share 7 brownies how many brownies should each person get? Pls show your work
=> 3 people share 7 brownies
=> 7 ÷ 3
=> 2.3333333
=> 2.3
Therefore, each person takes 2 1/3
Answer:
2 ⅓
Step-by-step explanation:
division is the same as a fraction
the dividend is the numerator and the divisor is the denominator
7÷3 is the same as 7/3
change 7/3 into a mixed number which is 2 ⅓

Answer:
D, B, C
Step-by-step explanation:
Because even though this is not a right triangle, it's super close. Therefore we can call side DC the SL, meaning angle C is larger. Angle D is largest, then B, then C.
The school that Brenda goes to is selling tickets to a fall musical. On the first day of the ticket
sales the school sold 4 senior citizen tickets and 6 child tickets for a total of $76. The school
took in $23 on the second day by selling 1 senior citizen ticket and 2 child tickets. What is the
price of one senior citizen ticket and one child ticket?
We can form two equations, let the price of a senior ticket be s and the price of a child ticket be c.
We have from day 1:
A: 3s + 9c = 75
And from day 2:
B: 8s + 5c = 67
Now we can rewrite A as:
A: 24s + 72c = 600
And can rewrite B as:
B: 24s + 15c = 201
Now A-B can be written as:
A-B: 57c = 399
So c = 7
Now substituting this back into A we get:
A: 3s + 63 = 75
A: 3s = 12
So s = 4
We have the price of a senior ticket is $4 and the price of a child ticket is $7 (idk if this is right hope it is!!!)

Frederick, Josiah, and Shawnda each had 2 rolls of raffle tickets with 12 tickets in each roll.
Josiah hands out half of his tickets and Shawnda hands out one fourth of her tickets.
How many tickets do they have left altogether?
Answer:
they all have 52 left altogether
Step-by-step explanation:
they all have 2 rolls with 12 so that means they all have 24 if josiah hands out half of his tickets he would have 12 tickets left
If shawnda hands out 1 fourth of her tickets she will have 18 tickets
24 + 12 + 18 =54
How do you graph y=-1x+4
Step-by-step explanation:
You will put the y-intercept at (0,4) and the slope will be -1
Here are some points on the line you can graph: (0,4) (1,3) (2,2) etc.
What is the y-intercept of the function f(x) = - 2/9x + 1/3
Answer: 1/3
Step-by-step explanation:
If the equation of a line is given in the form y=mx+b, then the y-intercept is the value of b.
The first of three numbers is one-third the value of second number. The second number is 5 less than the third number. If twice the third number is 5 less than the second number, which of the following equations could be used to find the value of the first number, if the first number is represented by x?
Answer: [tex]2(3x+5)=3x-2[/tex] , required equation.
Step-by-step explanation:
As per given we have,
First number = [tex]\dfrac13[/tex] of second number. (i)
Second number = Third number - 5 (ii)
2 (third number)= Second number - 5 (iii)
Put x= first number in (i).
so, [tex]x=\dfrac13[/tex] of second number.
⇒ second number =[tex]3\times x=3x[/tex]
From (ii)
[tex]3x=[/tex] Third number - 5
⇒ Third number =[tex]3x+5[/tex]
From (iii)
[tex]2(3x+5)=3x-2[/tex] , required equation.
Which choice is the equation of the line that passes through the point (5, 19) and has a slope of m =12 and is written in slope-intercept form?
Answer: y = 12x - 41
Step-by-step explanation:
The choices are not given, but you can figure this out.
Slope intercept form is y = mx + b
Substitute the y and x-values into the equation to calculate b, the y-intercept.
19 = 12(5) + b
19 = 60 + b
-60 + 19 =b
-41 = b
Write the equation with y and x, include the given slope and the calculated y-intercept:
y = 12x + 41

Felica is trying to simplify the expression 9 + (8 x 9) - (18\3
Answer:
The answer is 75.
Step-by-step explanation:
First, we apply the rule of PEMDAS (or whatever order of operations rule you have learned). In this equation, we first solve inside the parentheses.
8 x 9 = 72
18/3 = 6
Now, our equation has become 9 + 72 - 6. We can solve this left to right:
9 + 72 = 81
81 - 6 = 75
