Tell whether the angles are complementary or supplementary. Then find the value of x.
Answers
Answer:
this one is supplementary and x equals 31
Step-by-step explanation:
Remember, complementary angles add up to equal 90 degrees whereas supplementary angles add up to equal 180 degrees.
In this case, since your angles together form a straight line, they're supplementary angles. Now, to solve for x:
(3x + 25) + 2x = 180 (step 1: set the equation equal to 180)
5x + 25 = 180 (step 2: combine like terms)
-25 -25 (step 3: subtrace 25, BS)
5x = 155
5x / 5 = 155 / 5 (step 4: divide by 5, BS to get x by itself)
x = 31

Step-by-step explanation:
Supplementary angles mean they sum up to 180 degrees.
Therefore 124 + 2x + 4 = 180

You roll a number cube twice. What is the probability of rolling a 5 first and then rolling an even number? 1/4, 1/3, 1/12, 1/36?
Answers
Answer:
A = event of rolling a 2 on the first roll
P(A) = 1/6 because there is only one "2" out of six labels total on the number cube.
B = event of rolling an odd number on the second roll
P(B) = 3/6 = 1/2 since there are three odd numbers {1,3,5} out of six total
The events A and B are independent, so we can multiply the probabilities
P(A and B) = probability of both events happening simultaenously
P(A and B) = P(A)*P(B)
P(A and B) = (1/6)*(1/2)
P(A and B) = (1*1)/(6*2)
P(A and B) = 1/12
Final Answer: 1/12
Note: The fraction 1/12 is approximately equal to 0.0833

The equation is 2x + 2y = 20 and 3x = 2y. You have to solve it with substitution.
Answers
Answer:
3x+y=15, x+2y=20
Step-by-step explanation:
To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for that variable in the other equation.
Let this be Equation one :-
2x + 2y = 20 . . . . . . ( 1 )
and this be Equation two :-
3x = 2y. . . . . . . . . . . . .( 2 )
Simplifying equation one:-
↝ 2x + 2y = 20
↝ 2 (x + y) = 20
↝ x + y = 20/2
↝ x + y = (10 × 2)/2
↝ x + y = (10 ×1)/1
↝ x + y = 10
↝y = 10 - x
Put this value of y in Equation two:-
↦ 3x = 2y
↦ 3x = 2(10 - x)
↦ 3x = 2(10) - 2(x)
↦ 3x = 20 - 22x
↦ 3x + 2x = 20
↦ 5x = 20
↦ x = 20/5
↦ x = (4 × 5)/5
↦ x = (4 × 1)/1
↦ x = 4
Now Let's ind Value of y:-
put value of x in the equation one but simplified form.
↝ y = 10 - x
↝ y = 10 - 4
↝ y = 6
Now let Verify either the value of x and y:- .
↦ 2x + 2y = 20
put value of x and y in this equation.
↦ 2(4) + 2(6) = 20
↦ 2 × 4 + 2(6) = 20
↦ 8 + 2(6) = 20
↦ 8 + 2 × 6 = 20
↦ 8 + 12 = 20
↦ 20 = 20
LHS = RHS
.°. First equation is verified ✓.
Now Let's Verify 2 equation:
↝ 3x = 2y
put value of x and y.
↝3(4) = 2(6)
↝ 3 × 4 = 2(6)
↝12 = 2 × 6
↝12 = 12
LHS = RHS
.°. Second equation is verified ✓.

Write an equation to represent the following situation:
Adult tickets for a movie cost $12 and tickets for a child cost $8. If the theater collected $600 for the 10PM show, how many of each ticket did they sell?
How many children's tickets were sold if 26 adult tickets were sold?
What do the intercepts represent ?
Answers
There were $312 dollars worth of money sold from the adult tickets that were sold for the 10PM show.
$600 - $312 = $288
This means that there were $288 dollars worth of money sold from children’s tickets for the 10PM show.
Since each children ticket is $8, you would do
8x = $288
(X IS HOW MANY CHILDREN TICKETS THAT WERE SOLD)
Once you do that, you would simplify it by dividing 8x by 8 which would give you x by itself and do the same thing for the other side as you have to do the same for both sides of the equal sign. So, you would do $288 divided by 8 and get 36.
x = 36
To check our work, we will substitute the value of x into the equation
8(36) = $288
288 = $288
Therefore, there were 36 children tickets sold for the 10PM show.
Answer:
A. 36 children tickets
B. The intercepts of this equation represent how many tickets one type of ticket would have sold if the other type of ticket was not bought at all.
Step-by-step explanation:
So lets start with what we know
Adult tickets = $12
Children Ticket = $8
The theater collected $600.
So with this information, we can write down the equation
12x + 8y = 600
Note: x is the variable for the number of adult tickets and y is the variable for the number of children tickets
Find the amount of children tickets sold if 26 adult tickets were sold
So, this problem is trying to make us solve for y, if x = 26. Let's plug in the values and start solving for that value!
Solve for y if x = 26
12x + 8y = 600
12(26) + 8y = 600
312 + 8y = 600
-312 -312
8y = 288
8y / 8 = 288 / 8
y = 36
So, we have our answer as y = 36.
Solution Statement:
If 26 adult tickets are sold, 36 children tickets must be sold if the total amount collected was $600.
The intercepts of this equation represent how many tickets one type of ticket would have sold if the other type of ticket was not bought at all.

The answer is 15 units.
Step-by-step explanation:
This is the Pythagorean theorem (a^2+b^2=c^2).
We can see that from A to C it is 9 units down. We also know that from C to B it is 12 units long. Using the Pythagorean theorem, we square both numbers, then add them, then take the square root.
9x9=81
12x12=144
144+81=225
The square root of 225=15 *since 15x15=225)*
Therefore A to B is 15 units long!
