Poppy has one bag of beads. She is going to make three difference necklaces.
For the first necklace, she needs 3/8 of a bag of beads. For the second, she
needs 1/8 of a bag of beads. For the third, she needs 5/8 of a bag. What
fraction of a bag of beads does she need? Does she have enough? Explain.
Answer:
9/8 of a bag
she doesn't have enough beads.
Step-by-step explanation:
Bag of bead poppy has = 1
Bag of bead needed for necklace 1 = 3/8 of a bag
Bag of bead needed for necklace 2 = 1/8 of a bag
Bag of bead needed for necklace 3 = 5/8 of a bag
Total bag of beads needed = 3/8 + 1/8 + 5/8
= (3+1+5)/8
= 9/8
She needs 9/8 of a bag of bead
9/8 = 1 1/8
Therefore, she doesn't have enough beads.
The first term in a sequence is 13. The term to term rule is "take away 5" write an expression in terms of n , for the nth term of the sequence

Answer:
an = 13 -5(n -1)
Step-by-step explanation:
The "take away 5" rule means the common difference between terms is d=-5. For first term a1=13, the n-th term is ...
an = a1 +d(n -1)

Dana bought 12 pizzas for a Math Club party. Some were pepperoni pizzas that $11.00 each,
and the rest were mushroom pizzas that cost $9.50 each. She paid $124.50 for the pizzas. How
many pepperoni pizzas did she buy
Answer:
7 pepperoni pizzas
Step-by-step explanation:
First, you take the biggest number and subtract it by 9.5 until you get a number that can be divided into 11 which is 77.
Answer:
7 pepperoni pizzas
Step-by-step explanation:
Where p = # of pepperoni pizzas and m = # of mushroom pizzas
124.50 = 11p + 9.5m
Now you need to guess and check:
Use this equation: (124.5 - 11 * p) / 9.5 and replace p with whole numbers until you get a whole number as the output
I got p=7 and m=5
So she bought 7 pepperoni pizzas
Which point is located on the line represented by y = -3x + 4? A) (4,8) B) (4-8) C) (-4, 8) D) (-4,-8)
Answer:
B
Step-by-step explanation:
To determine which point lies on the line, substitute the x- coordinate of the point into the equation and if the value equals the y- coordinate of the point then it lies on the line.
A (4, 8)
y = - 3(4) + 4 = - 12 + 4 = - 8 ≠ 8 ← not on line
B (4, - 8 )
y = - 3(4) + 4 = - 12 + 4 = - 8 ← lies on line
C (- 4, 8 )
y = - 3(- 4) + 4 = 12 + 4 = 16 ≠ 8 ← not on line
D (- 4, - 8 )
y = - 3(- 4) + 4 = 12 + 4 = 16 ≠ - 8 ← not on line
The point lying on the line is (4, - 8 ) → B

Answer:
La²+8La+16 = La²+70
Step-by-step explanation:
8La+16 = 70
8La=70-16
La=54/8
La= 6.75
Area b = (6.75+4)*(6.75+4)
Area b = 10.75*10.75
Area b =115.563
The area of a square is the square of its side lengths
The area of square B is 116 centimeter square
Let the side length of square A be (a), and the side length of square B be (b)
So, we have:
[tex]\mathbf{A_a = a^2}[/tex]
[tex]\mathbf{A_b = b^2}[/tex]
From the question, we have:
[tex]\mathbf{A_b = 70 + a^2}[/tex]
[tex]\mathbf{b = 4 + a}[/tex]
Take square of both sides
[tex]\mathbf{b^2 = (4 + a)^2}[/tex]
[tex]\mathbf{b^2 = 16 + 8a+ a^2}[/tex]
Substitute [tex]\mathbf{b^2 = 16 + 8a+ a^2}[/tex] in [tex]\mathbf{A_b = b^2}[/tex]
[tex]\mathbf{A_b = 16 + 8a+ a^2}[/tex]
So, we have:
[tex]\mathbf{16 + 8a+ a^2 = 70 + a^2}[/tex]
Subtract a^2 from both sides
[tex]\mathbf{16 + 8a = 70}\\[/tex]
Subtract 16 from both sides
[tex]\mathbf{8a = 54}[/tex]
Divide both sides by 8
[tex]\mathbf{a = 6.75}[/tex]
Recall that:
[tex]\mathbf{A_b = 70 + a^2}[/tex]
So, we have:
[tex]\mathbf{A_b = 70 + 6.75^2}[/tex]
[tex]\mathbf{A_b = 115.5625}[/tex]
Approximate
[tex]\mathbf{A_b = 116}[/tex]
Hence, the area of square B is 116 centimeter square

Solve for x:
x/7 - 6 = 3
A. 27
B. -63
C. -27
D. 63
Answer:
D. 63
Step-by-step explanation:
First, add 6 to both sides:
[tex]\frac{x}{7}[/tex] - 6 = 3
[tex]\frac{x}{7}[/tex] = 9
Multiply each side by 7
x = 63
So, the correct answer is D. 63
Simplify 6⋅ (x+3)
Apply the distributive property.
6x+6⋅3=x⋅76x+6⋅3=x⋅7
Multiply 66 by 33.
6x+18=x⋅76x+18=x⋅7
Move 77 to the left of xx.
6x+18=7x
Move all terms containing x to the left side of the equation.
subtract 7x7x from both sides of the equation.
6x+18−7x=06x+18-7x=0
Subtract 7x7x from 6x6x.
−x+18=0-x+18=0
Subtract 1818 from both sides of the equation.
−x=−18-x=-18
Multiply each term in −x=−18-x=-18 by −1
Multiply −1-1 by −1-1.
1x=(−18)⋅−11x=(-18)⋅-1
Multiply xx by 11.
x=(−18)⋅−1x=(-18)⋅-1
Multiply−18-18 by −1-1.
x=18

A group of 3 friends went to a movie. They paid $15 for a bucket of popcorn. All the
movie tickets were the same price. They paid $51.75 total. Which equation represents
the cost of the tickets?
Answer:
51.75- 15= 36.75
36.75/3= 12.25 per ticket
Answer:
51.75 - 15 / 3
Step-by-step explanation:
$15 for a bucket of popcorn is separate from the tickets, so you subtract that from the sum.
Then you should have 36.75.
36.75 / 3 = 12.25

B. 196πx² + 392πx + 196π
Step-by-step explanation:
Total surface area of a sphere = 4πr²
Radius, r = 7x + 7
Total surface area of a sphere = 4πr²
= 4 * π * (7x + 7)²
= 4π * (7x + 7) * (7x + 7)
= 4π * 49x² + 49x + 49x + 49
= 4π * (49x² + 98x + 49)
= 196πx² + 392πx + 196π
B. 196πx² + 392πx + 196π
