If x is the midpoint of -21 and 18, find the value of x.
midpoint =
Answers
The distance from -21 to 18 would be 39 units ( -21 to 0 is 21 and from 0 to 18 is 18 , 21 +18 = 39)
To find the midpoint distance, divide the total distance by 2:
x = 39/2
x = 19.5
Now to find the midpoint, either add 19.5 to -21 or subtract 19.5 from 18.
Midpoint = -1.5
Answer:
−1½ = x
Step-by-step explanation:
First, find the range in between 18 and −21, which is 39:
Take half of that range, then add that to −21:

The algebraic expression for "4 inches more than twice Julie’s height" is 2x + 4, where "x" represents Julie's height in inches.
To translate the phrase "4 inches more than twice Julie’s height" into an algebraic expression, we use the variable "x" to represent Julie’s height.
Represent Julie's height with the variable "x".
Twice Julie's height is 2 times "x", which can be expressed as 2x.
Add "4 inches more" to the twice Julie's height, resulting in 2x + 4.
The final algebraic expression is 2x + 4, which represents "4 inches more than twice Julie’s height" in terms of the variable "x."
For example, if Julie's height is 5 inches (x = 5), the expression evaluates to 2(5) + 4 = 14, meaning she is 14 inches tall in this context.

Answer: y=-2x+12
Step-by-step explanation:
The slope goes down which makes it negative and the two yellow points make a line with a slope of =2. If you follow the line up, it would cross the y-intersection at 12. So the final line is y=-2x+12

The volume of the pond is 48 cubic feet. Then the weight of the water in the pond will be 2,976 pounds.
What is the volume of the rectangular prism?
Let the prism with a length of L, a width of W, and a height of H. Then the volume of the prism is given as
V = L x W x H
Water weighs about 62 pounds per cubic foot. The pond is 6 feet long and 4 feet wide. If the water pond is 2 feet deep. Then the volume of the water pond is calculated as,
V = L x W x H
V = 6 x 2 x 4
V = 48 cubic feet
Then the weight of the water in the pond will be given as,
W = 62 x 48
W = 2,976 pounds
The volume of the pond is 48 cubic feet. Then the weight of the water in the pond will be 2,976 pounds.

Answer:
Based on the number of cookies each girl made and if Kristina and Liz made the same number of cookies, then Heather made 4.2 dozen cookies.
Step-by-step explanation:
In order to find the number of cookies that Heather made, you need to set up two equations that represent the number of cookies that Kristina and Liz each made. Since Kristina made 2.4 dozen less than 6 times as many dozen as Heather, we can represent that with the equation 6c - 2.4. Since Liz made 1.8 dozen more than 5 times as many dozen as Heather, we can represent that with the equation 5c + 1.8. We can set both equations equal to each other since Liz and Kristina made the same number, so 6c - 2.4 = 5c + 1.8. Solving for 'c', which represents how many dozen cookies Heather made, we get 4.2
