Answer:
AB = 14
DE =7
Step-by-step explanation:
Remark
AB
Opposite sides of a parallelogram are equal.
AB = CD
AB = 14
DE
According to the diagram AE = 19
AD = 26 which is the same size as BC
DE = 26 - 19 = 7
DE = 7
complete the equation so that it has infinitely many solutions
4(x/8-2)=1/4(2x-___)
4(x/8 - 2) = 1/4(2x - 1/2) is the complete equations for having infinitely many solutions.
What are simultaneous equations?We know two simultaneous equations have a unique solution when they intersect at a point,
when they are parallel they have no solution and when they are coinciding they have an infinite no. of solutions.
Given, 4( x/8 - 2) = 1/4(2x -___.
(1/2)x - 8 = (1/8)x - ___.
Now, RHS is half of RHS so the blank space should be (-8/4) = -2.
And we know if one equation is some constant multiple of another they are also coinciding and have an infinite no. of solutions.

7 + X = 2x-5
3
Answer:
x = 60
Step-by-step explanation:
subtract 7 from both sides:
7 + x - 7 = 2x - 53 - 7
Simplify:
x = 2x - 60
Subtract 2x from both sides:
x - 2x = 2x - 60 - 2x
Simplify:
-x = -60
Divide by -1=

Derrick needs to sell a minimum of 100 orders each month to make it into the sales winners circle. He has already sold 45 orders this month. He still needs to sell s more orders. Which inequality can be used to find the possible values for s? s−45>100
s−45<100 s+45≤100 s+45≥100
Answer:
s+45≥100
Step-by-step explanation:
"A minimum of" means either the same amount or more. So, the total amount he sells (s + 45) needs to be greater than or equal to 100.

For answer A, we add 6^2 (36) and 8^2(64) to get 10^2 (100). This is a right triangle.
For question B, we add [tex]\sqrt{3}[/tex] ^2 (3) and [tex]\sqrt{8}[/tex]^2 (8) to get [tex]\sqrt{11}[/tex]. This is a right triangle.

trueWhich of the following graphs could represent the volume of water in a cylinder as a
function of its height? Explain your reasoning.
Answer:
It is A
Step-by-step explanation:
It starts from origin
The first graph represent the volume of water in a cylinder as a
function of its height.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
The first graph with a straight line passing through the origin could represent the volume of water in a cylinder as a function of its height.
This is because the formula for the volume of a cylinder is V = πr²h, where r is the radius and h is the height.
If we keep the radius constant and vary the height, we can see that the volume of the cylinder increases linearly with the height. In other words, the volume is directly proportional to the height.
Since the line passes through the origin, this indicates that when the height is zero, the volume is also zero.
This is consistent with the fact that a cylinder with zero height has zero volume.
Hence, the first graph represent the volume of water in a cylinder as a
function of its height.

Answer:
15 miles
Step-by-step explanation:
They both ran a total of 9 laps and 9 laps = 27 miles
This means each lap is 3 miles.
So Luigi ran 15 miles cause he ran 5 lap and each lap is 3 miles
