Part A: Larry earned $11 walking his neighbors' dogs on Saturday. He earned some extra money on Sunday doing the same thing. Write an expression with a variable that shows the total amount of money Larry has earned Saturday and Sunday.
Part B: Larry was able to walk 4 more than twice as many dogs as his friend Kyle. Write an algebraic expression to represent the number of dogs Larry walked compared with Kyle.
Answer:
Part A: T stands for total money earned and S stands for money earned on Sunday
T = 11 + S
Part B: We know Larry walked AT LEAST twice the amount of dogs than Kyle. So, L standing for Larry and K for Kyle:
L = 2(K)
But, it tells us he walked twice, plus 4 more. So our final equation will be:
L = 2(K) + 4
Step-by-step explanation:
The solution is : y= 11+x, is the expression with a variable that shows the total amount of money Larry has earned Saturday and Sunday.
The algebraic expression to represent the number of dogs Larry walked compared with Kyle is 2x +4 .
What is an expression?An expression is any mathematical statement which consists of numbers, variables and an arithmetic operation between them. In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
here, we have,
Given data
Larry earned $11 walking his neighbors' dogs on Saturday
Also, he earned some extra amount say x dollars on Sundays
let the total earnings be y
Therefore the total earnings can be expressed as
y= 11+x
next part:
It is given in the question that
Larry was able to walk 4 more than twice as many dogs as his friend Kyle have.
Let number of dogs Kyle has = x
and Let Larry walks y miles.
According to the given data
y = 2x + 4
Therefore , the algebraic expression to represent the number of dogs Larry walked compared with Kyle is 2x +4 .
Hence, The solution is : y= 11+x, is the expression with a variable that shows the total amount of money Larry has earned Saturday and Sunday.
And, the algebraic expression to represent the number of dogs Larry walked compared with Kyle is 2x +4 .

The height of a mountain is 24,000 feet. Of this height, 22,000 feet is above sea level and 2,000 feet is below sea level. Which set of integers represents the heights of the mountain above and below sea levels? pick the right expression that equal the word problem.
A. { 22,000, 2,000}
B. { 22,000, 2,000}
C. { 22,000, 2,000}
The answer is A {+22,000 -2,000}
This is because sea level is counted as 0 on a topographical map and any distance below sea level is counted in -ft. So if you the problem is amount above sea level to amount below sea level then you have 22,000 above sea level which would be +22,000 ft. And two thousand below. Then you just put that in the brackets “{}” and you are done.
Hope this helps.
Answer: twenty two thousand has a greater integers than two thousand
Step-by-step explanation:
In a game the player wins if he rolls a 4 on a number cube. If the number cube is rolled 24 times, then what is a reasonable prediction for the number of unsuccessful rolls?
============================================
Explanation:
If we want to roll a 4, then theoretically we have a probability of 1/6 of that happening. This is because there's 1 face that has "4" labeled on it, out of 6 faces total.
If we roll the cube 24 times, then we expect 24*(1/6) = 24/6 = 4 instances of the "4" show up. Of course, due to the random nature of this event, it's not guaranteed. So that's why we use the "expect" there.
We expect 4 times to get successful rolls, which means we have 24-4 = 20 unsuccessful rolls. This value (20) is also an expected or predicted value, and not a guarantee.

1. Write down four different numbers with a median of 4.5
2. Write down six different numbers with a median of 0
No Wrong answers Pls
1. Four different numbers that with a median of 4.5 are 3, 4, 5, 6.
2. Six different numbers that satisfy this condition: -5, -2, -1, 1, 2, 5.
1. To have a median of 4.5, we need a set of numbers that is arranged in increasing order.
Here are four different numbers that satisfy this condition: 3, 4, 5, 6.
When arranged in ascending order, the median of these numbers is indeed 4.5 since it is the average of the two middle numbers, 4 and 5.
2. To have a median of 0, we can create a set of six different numbers that include both positive and negative values.
Here's an example: -5, -2, -1, 1, 2, 5.
When arranged in ascending order, the median is 0 since it is the middle value.

If a = 8, b = 4, and c = 10, what is a(b + c)?
A. 22
B. 112
C. 320
D. 2560
Answer:
B: 112
Step-by-step explanation:
8(4 + 10)
add 4 + 10 = 14
8 x 14 = 112
Mark brainliest please
Answer:
A(b + c) = 112
Step-by-step explanation: For this equation you rewrite the equation with the numbers in place of the variable. This would loook like 8(4 + 10). Next to follow pemdas we do parenthesis first, 4 + 10 = 14. Then you multiply 14 x 8 which is 112. I checked this on a calculator and on paper and both got the same answer.
Hope this helps.

Kaitlyn bakes two rectangular cakes to put on top of each other. Each cake is 6 inches wide, 12 inches long and 3 inches high. She removes the cake from the pan to frost it. How many square inches of frosting does she need for both cakes?
Use one of these:
216 in2
360 in2
126 in2
288 in2
The number of square inches of frosting that she needs for both cakes will be 288 square inches.
What is the surface area of the rectangular prism?Let the prism with a length of L, a width of W, and a height of H. Then the surface area of the prism is given as
SA = 2(LW + WH + HL)
Two rectangular cakes are baked by Kaitlyn and stacked on top of one another. Each cake has a 6-inch width, a 12-inch length, and a 3-inch height. To decorate the cake, she takes it out of the pan.
Then the surface area is calculated as,
SA = 2 x (6 x 12 + 12 x (3 + 3) + (3 + 3) x 6) - 12 x 6
SA = 2 x (72 + 72 + 36) - 72
SA = 2 x 180 - 72
SA = 288 square inches
The number of square inches of frosting that she needs for both cakes will be 288 square inches.
