Step-by-step explanation:
∠6 = 10x
∠7 = 5x
∠6 = ∠8
∠7 = ∠5
Find value of x
∠5 + ∠6 + ∠7 + ∠8 = 360
5x + 10x + 5x + 10x = 360
30x = 360
x = 360/30
x = 12°

IN A CLASS OF 60 STUDENTS, 25 PLAYS BASKETBALL, 2O PLAY VOLLEYBALL, AND 10 STUDENTS PLAY BOTH OF THEM. HOW MANY STUDENTS PLAY NEITHER BASKETBALL NOR VOLLEYBALL ?
Answer:
5
Step-by-step explanation:
60-25=35
35-20=15
15-10=5
5 people dont play either of them
Answer:
25
Step-by-step explanation:
To solve this, we can add the number of basketball players and the number of volleyball players:
25 + 20 = 45
But we know that there are ten players who are counted twice because they play both. So we subtract 10:
45 - 10 = 35
And that is the total number of students who play either basketball or volleyball. Now to figure out those that play neither sport we subtract the number of students by the number of players:
60 - 35 = 25
That’s the number of students who don’t play one of those sports.
How do I solve this?
Answer:
X = 10
Step-by-step explanation:
<1 = 2x + 10
<2 = x + 20
<3 = 180 - 6x (linear angles = 180 degrees)
<1 + <2 + <3 = 180 degrees
2x + 10 + x + 20 + 180 - 6x = 180
-3x + 210 = 180
-3x = 180 - 210
x = -30/-3
x = 10

The youth group is going on a trip to the state fair. The trip costs $62. Included in that price is $14 for a concert ticket and the cost of 2 passes, one for the rides and one for the game booths. Each of the passes costs the same price. Write an equation representing the cost of the trip, and determine the price of one pass. Solve your equation by showing your work and steps.
Answer:
11+2x= 52 , $20.50 equal one pass
Step-by-step explanation:52 is the total and $11 is included in that total. So you have part of your equation : 11 + something = 52. In order to find that " something " you have to set up a variable : 2x , 2 because that is the amount of passes bought and X because you don't know the cost of the passes yet. You now have your equation : 11+2x=52. Next you isolate the "2x" by subtracting eleven from itself and what you do to one side of the equation you have to do to the other, so you subtract 11 from 52 and are left with 41 . You then have the simplified equation : 2x=41 . Now you're going to isolate the variable by dividing 2x by 2 and doing the same to 41. You're then left with X= 20.50 , the cost of one ticket

You can multiply by √5/√5 as you have done, and as conventionally taught, or you can multiply by 5/5 under the radical to make the denominator a perfect square.

Hi there!
We're given a right triangle (notice the 90 degree angle), the measure of one of the legs (one of the sides that make up the right angle) as 46, the other one as y, and one of the angles as 26°
We want to solve for y
We can use a trigonometric ratio to do that.
First, let's recall the three most-well known ratios:
Sine is [tex]\frac{opposite}{hypotenuse}[/tex]
Cosine is [tex]\frac{adjacent}{hypotenuse}[/tex]
Tangent is [tex]\frac{opposite}{adjacent}[/tex]
Since we are given one of the angles, let's find out which sides are the opposite, adjacent, and hypotenuse, in reference to the given angle (the 26° angle)
In reference to that angle, the side opposite to that angle (also the side known as "opposite) is the side marked as 46, the adjacent side is y, and the hypotenuse is the unmarked side
Since we know the opposite and adjacent, let's use the ratio for tangent
Since we based our labels off of the 26 degree angle, the tangent ratio is the tangent OF 26, or tan(26)
tan(26)=[tex]\frac{46}{y}[/tex]
Now we need to solve the equation
Start by multiplying both sides by y
tan(26)*y=46
Divide both sides by tan(26)
y=[tex]\frac{46}{tan(26)}[/tex]
Plug [tex]\frac{46}{tan(26)}[/tex] into your calculator, and remember to have the calculator on degree mode
[tex]\frac{46}{tan(26)}[/tex]≈94.31
Remember that [tex]\frac{46}{tan(26)}[/tex] is equal to y, which means that y is about 94.31

What is quadratic equation?A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is ax² + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term.
Given:
f(x) = ax² + bx + c
The first condition for an equation to be a quadratic equation is the coefficient of x² is a non-zero term(a ≠ 0).
For writing a quadratic equation in standard form, the x² term is written first, followed by the x term, and finally, the constant term is written.
Hence, The constants a, b, and c must be real numbers with a not ever equal to zero.

9 ) Jason bought 9 new baseball trading cards to add to his collection. The next day his dog ate half of his collection. There are now only 31 cards left. How many cards did Jason start with ?
Answer:
He started with 53 cards
Step-by-step explanation:
He has 31 now
If 31 is half of what he had, then we need to double it
31 x 2 = 62
If he had bought 9, then we need to do the opposite
62 - 9 = 53

Answer:
[tex]w=15.5[/tex]
[tex]w=\frac{31}{2}[/tex]
Equation:
[tex]2w+4=35[/tex]
Step-by-step explanation:
[tex]2w+4=35\\2w=31\\w=15.5[/tex]
Hidden Steps:
1) Subtract 4 on each side of the equation:
[tex]2w+4-4=21\\35-4=31[/tex]
2) Divide each side of the equation by 2:
[tex]2w[/tex] ÷ [tex]2=w[/tex]
[tex]31[/tex] ÷ [tex]2=15.5-or-\frac{31}{2}[/tex]
Answer:
Equation: 2w + 4 = 35
Weight: 15.5
Step-by-step explanation:
Let w be the weight of each checked bag.
The weight of Carl's 2 checked bags is 2w kg. The weight of his backpack is 4kg. The total weight of his baggage is 2w + 4 kg.
Since his total baggage weighs 35 kg, let us set this to 35:
2w + 4 = 35
Now you solve:
1. 2w + 4 = 35
2. 2w = 35-4
3. 2w = 31
4. w = 31/2
5. w = 15.5
Therefore, the equation is 2w + 4 = 35 and the solution to " w " is 15.5 kg.
