Answer:
r=21+y
Step-by-step explanation:
its telling you that r is going to be equal to the rest of the equation, so we start with
r=
then, it mentions the sum of 21 and y, so this would be represented as
21+y
since r is equal to the sum of 21 and y, your answer is
r=21+y
(because of comutitive property, r=y+21 is also an acceptable answer.)

12
10
8
24
Answer:
10
Step-by-step explanation:
10/4 = 2.5(fraction)
12/4 = 3
8/4 = 2
24/4 = 6
The numbers 2, 6, 10, and so on are not divisible by the 4 but they are even numbers. Then the correct option is B.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The statement is given below.
“All even numbers are divisible by 4”
The statement “All even numbers are divisible by 4” is false.
Because the numbers 2, 6, 10, and so on are not divisible by the 4 but they are even numbers.
Not all even numbers are divisible by 4, but some numbers are divisible by 4.
Then the correct option is B.

1. Leslie visits a local department store in order to purchase summer clothes. The
price of the dress is $40. The dress is marked up 25%. What is the selling price of
the dress?
Answer:
$50
Step-by-step explanation:
Given data
We are given that the price is $40
the markup percent is 25%
Hence the price will be
40+25% of 40
=40+ 25/100*40
=40+ 0.25*40
=40+10
=$50
Therefore, the price of the dress is $50

Step-by-step explanation:
A circle has a secant and a tangent that intersect outside of the circle. If the measure of ∠ is 29° and the measure of is 45°, then determine the measure of
Answer:
CD = 103°
Step-by-step explanation:
The secant- tangent angle BAD is half the difference of the intercepted arcs, that is
[tex]\frac{1}{2}[/tex] ( CD - BD ) = 29° ( multiply both sides by 2 )
CD - BD = 58°
CD - 45° = 58° ( add 45° to both sides )
CD = 103°

Where is the midpoint of AB if A(6, 4) and B(5,-2)?
A) (11,2)
B (11,6)
C) (5.5,3)
D (5.5,1)
Answer:
Step-by-step explanation:
The midpoint is just the average coordinates of the endpoints.
mp=((x1+x2)/2, (y1+y2)/2), we have points (6,4) and (5,-2)
mp=((6+5)/2, (4-2)/2)
mp=(5.5, 1)
So D is the answer.
If there is one obtuse angle, how many angles are
acute?

Answer: a .2
Step-by-step explanation: A triangle is 180 degrees. If one angle is obtuse, it is more than 90 degrees. That leaves the two remaining angles having to add up to less than 90 degrees combined. So both have to be acute.

Answer:
∠H = 50°∠A = 80°∠W = 130°Step-by-step explanation:
It is helpful to remember that opposite angles of an inscribed quadrilateral are supplementary. This lets you find the value of m.
∠A +∠K = 180°
8m° +10m° = 180°
18m = 180
m = 180/18 = 10
Using this value we can find ...
∠H = 5m° = 5·10° = 50°
∠A = 8m° = 8·10° = 80°
∠W = 180° -∠H = 180° -50° = 130°
