Step-by-step explanation:
The total no of pieces is 35. Let Gwen has B black pieces and R red pieces.
(a) She bought 4 times as many red pieces as she did black pieces. It means,
Red pieces = 4B
Equations that represents the number of pieces of each kind of licorice that Gwen bought are :
R + B = 35 ....(1)
and
R = 4B ....(2)
((b) Put equation (2) in equation (1)
4B + B = 35
5B = 35
B = 7
Put the value of B in equation (2)
R = 4(7) = 28
(c) There are 7 black and 28 red pieces of licorice.
Sally is selling two types of seashells by the seashore. She is selling large and small shells. She sells small shells for 2 dollars each and large shells for 5 dollars each. She sold a combined 15 shells for total of 60 dollars. How many of each type of shell did she sell? Show your work.
A - 5 small shells and 10 large shells
B - 10 small shells and 5 large shells
C - 7 small shells and 8 large shells
D - 8 small shells and 7 large shells
Answer:
The answer is A
Step-by-step explanation:
If you plug in the numbers it looks like this:
(A) 5(2) + 10(5) = 60
(B) 10(2) + 5(5) = 45
(C) 7(2) + 8(5) = 54
(D) 8(2) + 7(5)
so a is the only one that equals 60
She will sell 5 small shells and 10 large shells. The answer is A.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

(x – 4)2 = -9 has no real solution
Answer:
x = -1/2
Step-by-step explanation:
(x - 4) * 2 = -9
Divide both sides by 2:
x - 4 = - 9 / 2
Add 4 to both sides:
x = - 1 / 2.

Shane and Gemma share 35 sweets in the ratio 1:4
1
Gemma eats 10 of her sweets and then gives Shane 2 of the sweets she has left.
(c) How many sweets does Shane have now?
Answer:
Shane has 9 sweats now.
Step-by-step explanation:
Given that Shane and Gemma share 35 sweets in the ratio 1:4.
Let the share of Shane be = 'x'
Let the share of Gemma be = '4x'
The combined share of Shane and Gemma = x + 4x = 5x
Total sweets they share = 35
so the equation becomes
5x = 35
x = 7
Thus,
Share of Shane = x = 7
Share of Gemma = 4x = 4(7) = 28
Gemma eats 10 sweets, so she has left with 28-10 = 18 sweets
Gemma gave 2 of the sweets she has left.
As Shane has already 7 sweats, so adding 2 in 7 sweats would make it 9 sweats.
Therefore, Shane has 9 sweats now.

What is the lines for and how do I solve X with them?
Answer:
the lines represent absolute value bars
[tex]x=0,10[/tex]
Step-by-step explanation:
STEP 1: Move all terms not containing |5−x| to the right side of the equation.
[tex]3|5-x|=15[/tex]
STEP 2: Divide each term by 3 and simplify.
[tex]|5-x|=5[/tex]
STEP 3: Remove the absolute value term. This creates a ± on the right side of the equation because |x|=±x.
5-x=±5
STEP 4: Set up the positive portion of the ± solution.
[tex]5-x=5[/tex]
STEP 5: Solve the first equation for x.
[tex]x=0[/tex]
STEP 6: Set up the negative portion of the ± solution.
[tex]5-x=-5[/tex]
STEP 7: Solve the second equation for x.

3 3/4 = r + 1/8
Answer:
r = 29/8 or 3 5/8
Step-by-step explanation:
so you need to make them have the same denominator so you multiply 3/4 by 2/2 to get that
this equals 6/8
add 3 so 24/8
then you subtract 1/8 from both sides
r = 29/8
simplify so 29/8 = 3 5/8

If you are framing a photo that is 4in by 7 in, and you want the frame to be the same width all around, and the total area of the frame and the photo is 130in squared, what is the width of the photo?
Answer:
3.36in
Step-by-step explanation:
The total surface area of the cardboard is expressed as;
TSA = 2(LW + LH + WH)
L is the length = 4in
W is the width
H is the height = 7in
TSA = 130in²
Substitute the given values into the formula and get the width W
TSA = 2(LW + LH + WH)
130 = 2(4W+4(7) + 7W)
130 = 2(11W+28)
130 = 22W+56
22W = 130 - 56
22S = 74
W = 74/22
W = 3.36in
hence the width of the photo is 3.36in

Step-by-step explanation:
Li deposited $17,500 into a bank account that earned simple interest each year. After 2 years, he had earned $2975 in interest.
No money was deposited into or withdrawn from the account.
What was the annual interest rate?
Enter your answer in the box.
Answer: 8.5%
Step-by-step explanation:
Formula : Simple interest = (Principal) x (annual interest rate) x (Time) (i)
Given: Principal : P = $ 17,500
Time : 2 years
Simple interest : I = $ 2975
Let r = annual
[tex]2975=17500\times(r)\times(2)[/tex]
[tex]\Rightarrow\ r=\dfrac{2975}{17500\times2}\\\\\Rightarrow\ r=0.085\\\\\Rightarrow\ r=0.085\times100\\\\\Rightarrow\ r=8.5\%[/tex]
Hence, The annual interest rate was 8.5%.
