Answered by Gauthmath must click thanks and mark brainliest
Answer: The correct answer is D.
Step-by-step explanation:
Since 3 of Rita's 8 friends don't want to play laser tag, Rita only has to pay for 5 of her friends to go.
So, the expression would be:
5 (8 - 3)
= 5 (5)
= $25

kim is 10 years older than laura. laura is twice as old as melissa. if melissa will be 1o years old in 5 years, how old is kim now
Answers
Answer:
Kim is 20 years old
Step-by-step explanation:
We have to make equations;
Kim= laura+10 so L+10
Laura is twice as old as Melissa so Laura will be
2 X M = 2M
Melissa is 5 years old nowInput values in to the equation
2M = 2X5= 10 years old (Laura)As Kim is 10 years older than Laura it will be 10+10
which will give the answer of 20The age of Kim is 20 years.
What is Equation?Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S (left hand side = right hand side).
Parts of an EquationThere are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides. Both sides should be equal to each other. An equation doesn't need to have multiple terms on either of the sides, having variables, and operators. An equation can be formed without these as well, for example, 5 + 10 = 15. This is an arithmetic equation with no variables. As opposed to this, an equation with variables is an algebraic equation.
Kim's age = laura' age +10 years
= x +10
As, Laura is twice as old as Melissa
Laura's age = 2*y
Now, Melissa is 5 years old now
So,
2y = 2X5= 10 years old
So, the Kim's age= 10+ 10 = 20 years old

draw two intersecting line segment AB and CD intersecting O. Measure the size of each pair of vertically opposite angles. Verify each pair of vertically opposite angles are equal.
Answers
When two line segments intersects, a set of vertically opposite angles are formed. So that by comparison of angles formed in the attachment, a set of vertically opposite angles formed are: >AOC and >BOD; then >AOD and >BOC.
A pair of vertically opposite angles are formed when two lines meet at a point. And the pair of vertically opposite angles formed are said to have equal size.
From the given question, line segment AB intersecting CD at point O would produce a set of vertically opposite angles. So that each pair has equal size.
From the attached diagram, it can be observed that;
m>AOC = m>BOC = m>AOD = m>BOD = [tex]90^{o}[/tex]
But;
m>AOC ≅ m>BOD = [tex]90^{o}[/tex] (vertically opposite angle property)
also,
m>AOD ≅ m>BOC = [tex]90^{o}[/tex] (vertically opposite angle property)
Therefore it can be verified that each pair of vertically opposite angles are equal.
NB: The required diagram to the question is herewith attached to this question for more clarifications and reference.

Step-by-step explanation:

A 32-ft pipe must be cut into three pieces. The longest piece will be twice as long as the shortest piece, and the medium-sized piece will be 4 feet longer than the shortest piece. Find the length of each piece of pipe.
Answers
Answer:
7, 11, 14 feet from shortest to longest
Step-by-step explanation:
Let's say that the shortest pipe is equal to x, and work from there.
The medium size piece is 4 feet longer than the shortest piece, so it is equal to 4+x
The longest piece is twice as long as the shortest piece, so it is equal to 2 * x.
The three pieces added up make up the 32 feet pipe, so we can write this as
(2*x) + (4+x) + x = 32
2*x + 4 + x + x = 32
4 * x + 4 = 32
subtract 4 from both sides to isolate the x and its coefficient
4 * x = 28
divide both sides by 4 to isolate the x
x= 7
Therefore, the shortest piece is x=7 feet long. The medium piece is x+4=11 feet long, and the longest piece is x*2=14 feet long

The area of the triangle shown is represented by A=s(s−21)(s−17)(s−10)−−−−−−−−−−−−−−−−−−−−√, where s is equal to half the perimeter. What is the height h of the triangle?
Answers
Answer:
9.88 units
Step-by-step explanation:
We are given that area of triangle is given by
[tex]A=\sqrt{s(s-21)(s-17)(s-10)}[/tex]
s=Half perimeter
By comparing with
[tex]A=\sqrt{s(s-a)(s-b)(s-c)}[/tex]
We get
a=21
b=17
c=10
[tex]s=\frac{a+b+c}{2}=\frac{21+17+10}{2}=24[/tex]
Now, the area
[tex]A=\sqrt{24(24-21)(24-17)(24-10)}[/tex]
A=84
Area of triangle, [tex]A=\frac{1}{2}\times bh[/tex]
b=17
[tex]84=\frac{1}{2}(17)(h)[/tex]
[tex]h=\frac{84\times 2}{17}[/tex]
[tex]h=9.88 units[/tex]
Hence, the height of the triangle=9.88 units
