Lily sold 18 items at the street fair. She sold bracelets for $6 each and necklaces for $5 each for a total of $101. Which system of equations can be used to find b, the number of bracelets she sold, and n, the number of necklaces she sold?
b + n = 101
6b + 5n = 18
b + n = 101
5b + 6n = 18
b + n = 18
6b + 5n = 101
b + n = 18
5b + 6n = 101
Answer:
6b + 5n = 101
Step-by-step explanation:
I hope this helps!
Answer:
6b+5n = 101 because if you look at each equation and back at the question you’ll understand that it’s asking for 6 bracelets plus 5 necklaces for a total of 101 dollars... hope this helped...and I need brainliest thx

what is the slope- intercept form of 4x+5y=20
Answer:
y = -4/5x + 4
General Formulas and Concepts:
Pre-Algebra
Equality PropertiesAlgebra I
Standard Form: Ax + By = C
Slope-Intercept Form: y = mx + b
m - slope b - y-interceptStep-by-step explanation:
Step 1: Define
Standard Form: 4x + 5y = 20
Step 2: Rewrite
Subtract 4x on both sides: 5y = 20 - 4xDivide 5 on both sides: y = 4 - 4/5xRearrange: y = -4/5x + 42) The spinner was spun 60 times. On 20 out of 60 times, the arrow landed on a blue section. What is the experimental probability of landing on a section that is blue?

x-4y=-12
what is this supposed to equal
Answer: X- 4y - 12=0
step by step explanation:
First, move the constant to the left by adding its opposite to both sides
x-4y -12 = 12-12 =
X-4y-12 = 0
So the answer is X- 4y - 12=0

If two sides and the angle that is not between them of one triangle are congruent to the corresponding two sides and the angle that is not between them of another triangle, then the congruency of those triangles cannot be determined.
Answer:
True
Step-by-step explanation:
The given parameters are;
Two triangles each with known measures of two sides of the triangle and a non included angle
Therefore, with the given information, each of the the triangles are undefined because the sides can be opened wider or narrowed to have two possible solutions, in the same manner a compass, having one leg at a fixed inclination to the drawing paper can have the second leg either come closer or go further than 90 degrees while the inclination of the one (first) leg remains the same.

Answer:
1. 3 cookies
2. 2 cups
3. 300 calories
4. $35 per month
5. k = y/x
6. If there is no constant (k)
Step-by-step explanation:
1. The number of cookies the factory makes in one minute = (The number of cookies the factory makes in 12 minutes)/(12 minutes)
∴ The number of cookies the factory makes in one minute = 36 cookies/(12 minutes) = 3 cookies/minute
The correct answer is 3 cookies
2. The number of cups of water that leak every minute = (The number of cups of water that leak in 1/4 minute) × (The number of 1/4 minute per minute)
The number of cups of water that leak every minute = 1/2 cup per 1/4 minute × 4_1/4 minute per minute
The number of cups of water that leak every minute = 1/2 × 4 = 2
The number of cups of water that leak every minute = 2 cups
3. 5 glazed donuts contains 750 calories
∴ 1 glazed donuts contains 750/5 = 150 calories

4. The charge of the cell phone company for 2 months = $70
The charge of the cell phone company for 6 months = $210
The constant rate per month = The rate of change of the cell phones companys charges
∴ The constant rate per month = (210 - 70)/(6 - 2) = 140/4 = 35
The constant rate (per month) for the service = $35 per month

What is number?A number is a mathematical object used to count, measure, and label. The original examples are the natural numbers 1, 2, 3, 4, and so forth. Numbers can be represented in language with number words.
here, we have,
given that,
-8 ≤ 4n < 12
=> -2≤ n <3
because, n is an integer => n ∈ {-2; -1; 0; 1; 2}
Hence, Answer is : n ={-2; -1; 0; 1; 2}.

Kate has an interior decorating business. She charges a base fee of $25 for each visit and $40 per hour for her labor. 1) Write a function rule to represent this situation for, C, the total cost and h number of hours. 2) Identify the domain and range for the situation. 3) Explain if the situation is discrete or continuous. (if there is no explanation, there will be no credit given) PLEASE I NEED FAST ILL GIVE BRAINLIEST
Answer:
1) C = $25 + $40 × h
2) The domain for the ≠unction is 0 ≤ h ≤ ∞
The range for the function is 25 ≤ C ≤ ∞
3) Continuous
Step-by-step explanation:
1) The given parameters are;
The base fee charged = $25
The amount charged for labor = $40/hour
The total cost for h number of hours is C = $25 + $40 × h
2) The domain for the ≠unction is 0 ≤ h ≤ ∞
The range for the function is 25 ≤ C ≤ ∞
3) The situation is continuous because the different input values of h can be infinite (from o to infinity)
