When Lucia plays golf at the Rolling Hills golf course, she loses about 12 balls on average. When she plays golf at the Meandering Meadows golf course, she loses about 8 balls on average. If Lucia lost approximately 100 balls after playing at Rolling Hills rr times and Meandering Meadows mm times, which of the following equation best represents the relationship between rr and mm?
When Lucia plays golf at the Rolling Hills golf course, she loses about 12 balls on average. When she plays golf at the Meandering Meadows golf course, she loses about 8 balls on average. If Lucia lost approximately 100 balls after playing at Rolling Hills rr times and Meandering Meadows mm times, which of the following equation best represents the relationship between rr and mm?
8r+12m=1008r+12m=100
12r+8m=10012r+8m=100
12r-8m=10012r−8m=100
8r-12m=1008r−12m=100
The relationship between the number of balls Lucia lost at the golf
courses can be expressed as an equation.
The equation that best represents the relationship between r and m is; 12·r + 8·m = 100Reasons:
The given parameters are;
The number of balls Lucia loses at the Rolling Hills, r = 12 balls
The number of balls Lucia loses at the Meandering Meadows, m = 8 balls
The total number of balls Lucia lost after playin at Rolling Hills and Meandering Meadows = 100 balls
The relationship between r and m is therefore;
Number of balls lost at Rolling Hills + Number of balls lost at Meandering Meadows = 100
12 × r + 8 × m = 100
12·r + 8·m = 100
The equation that best represents the relationship between r and m is therefore; 12·r + 8·m = 100

B is the correct answer ,,,
Answer: B
Step-by-step explanation:
You need spoons, cones, and bowls for your store. The spoons come in packs of 100, cones come in packs of 60, and cups come
in packs of 80.
1. How many spoons, cones, and cups will you have if you order 8 packs of each?
2. How many customers will you be able to serve? Will every person need a cup, spoon, and a cone?
3. If you estimate that you will have 1500 customers next week, how would you change your order to make sure everyone can be served?
Step-by-step explanation:
Number 1
Number of spoons= no of boxes × individual no of spoons
= 100 × 8 = 800 spoons.
Number of cones = no of cones in a box × no of boxes
= 60 × 8 = 480
Number of cup = no of cups in a box × no of boxes
= 80 × 8 = 640.
Total = 800 + 480 + 640 = 1920
Number 2
If everyone needs a cup, spoon and cones, it means they all need 3 items.
no of people you can serve = 1920 ÷ 3
= 640 people.

Emily took an airplane trip. Her plane flew an equal number of miles each hour. Write an equation to represent one way you can find how many miles Emily's plane flew each hour.
Use this to help you:
Air travel time: 12 hours
Destination: 2,184 miles
182.00 miles per hour
y = 182x will be the equation to represent one way you can find how many miles Emily's plane flew each hour.
What is the equation?A formula that expresses the connection between two words on each side of an indication. A calculation with an integer multiple is referred to as an equation. Algebra is widely used in equations. In performing calculations but unsure of the precise amount, algebra is utilized.
The information that is provided is
the air travel time is 12 hours
The destination miles will include 2,184 miles
Assuming the values of x and y
x = number of hours n
y = distance covered
The equation that will be made will be:
y = (2184 / 12)x
y = 182x
Therefore, the equation will be y = 182x.

What number is 133% of 200
Rewrite 133% as a decimal by dividing by 100:
133% = 1.33
Now multiply:
200 x 1.33 = 266
Answer: 266
133% of 200 = 266
