Since all of the variables are the same just do it normally like a normal equation then make sure to add the variable to your answer.
Solve for each variable
Answer:
a = 38
b = 54
c = b = 54
Step-by-step explanation:
[tex] a + 142 = 180\\ a = 180 - 142 = 38 \\ 88 + 38 + b = 180 \\ b = 180 - 126 = 54 \\ c = b = 54[/tex]

Given parallelogram ABCD,
find x.

B
(4x + 2)°
1249
C
D
Answer:
hey here is the correct answer
Answer:
x = 30.5
Step-by-step explanation:
The opposite angles of a parallelogram are congruent , then
4x + 2 = 124 ( subtract 2 from both sides )
4x = 122 ( divide both sides by 4 )
x = 30.5

The difference of the two numbers is 1.Their sum is 23.find the numbers
Answer:
11 and 12
Step-by-step explanation:
The two numbers will be called x and y. The sum of x and y is 23 and the difference is 1.
x + y = 23
x - y = 1
Add the equations together
x + y + x - y = 23 + 1
2x = 24
x = 12
y = x - 1
y = 11

A line segment can be drawn from each vertex of a polygon to every other vertex, forming the sides and
diagonals of the polygon. A square, for example, has 4 sides and 2 diagonals. Using combinations, write
an expression that would give you the total number of sides and diagonals for a polygon with
sides.
Answer:
n(n - 3)/2
Step-by-step explanation:
We are told that;
A square has 4 sides and 2 diagonals.
Now, a pentagon will have 5 sides and 5 diagonals
A hexagonal when drawn will have 6 sides and 9 diagonals
Thus, we see that;
When n = 4, d = 2
When n = 5, d = 5
When n = 6, d = 9
Using combination, we will find number of pairs of 2 vertices that can possibly be formed from n-vertices. Thereafter we will subtract n from that since it's neighboring vertices can't combine with the current one.
Thus, we have;
C(n, 2) - n
This gives s;
(n(n-1)/2) - n
Simplifying this gives;
(n(n - 1) - 2n)/2
>> (n² - n - 2n)/2
>> (n² - 3n)/2
>> n(n - 3)/2

Step-by-step explanation:
During testing, the experimental probability of completing a new game with a perfect score was found to be StartFraction 1 over 500 EndFraction. If 1,000,000 people buy and play the game when it is released, how many players will complete the game with a perfect score?
Given: 1/500 and 1,000,000
Multiply 1/500 & 1,000,000
1/500 * 1,000,000 = 2000
Thus, 2000 people are likely to complete the game with a perfect score
Olivia download music for $1.89 per song. She has a credit on her account for $3. Which expression could be used to represent the cost of the music if Olivia downloads m songs?
Answer:
Answer 3 (1.89m - 3)
Step-by-step explanation:
Since we know that the price per song is $1.89, that is going to be the part of the equation that goes with the variable.
Since she has a 3 dollar credit, this will reduce the cost of whatever amount of songs she is buying by 3 dollars, which means the second part of the equation is -3. You have your answer, 1.89m - 3.

Ellie is interested in getting a new phone. One phone company, phone 1 charges a monthly fee of 6$. They also charge 0.10$ per minute. Another company, phone 2, charges 5$ for a monthly fee and 0.25$ per minute. Write an equation for the total cost of each phone bill, where y is the total cost and x is the total number of minutes on the phone. Which company will allow Ellie to talk the longest is she only wants to spend 22$ a month
Answer:
Phone 1 will allow Ellie to talk the longest
Step-by-step explanation:
Phone 1:
(0.10x) + 6 = y
(0.10x) + 6 - 6 = 22 - 6
0.10/0.10x = 16/0.10
x = 160 minutes
Phone 2:
(0.25x) + 5 = y
(0.25x) + 5 - 5 = 22 - 5
0.25/0.25x = 17/0.25
x = 68 minutes

James adds vitamin drops to his fish tank to keep his fish healthy. If James
follows the instructions on the bottle of vitamins, how many capfuls should he add
to his 450-litre tank? (4 marks)
• 2 drops per 5 litres
of water
• 1 capful = 40 drops
Step-by-step explanation:
350/5=70 liters X 2 drops for every 5 liters=140 drops needed for the whole tank.
Since 1 cupful contains 40 drops, the we have this:
140 drops needed for the full tank/40 drops contained in one cup, or,
140/40=3 1/2=3.5 number of cupfuls needed for the full tank.
hopefully this helps
