HELP Lines a, b, c, and d intersect as shown below.
What is x
Answer:
x = 109°
Step-by-step explanation:
Angle x lies outside of line d, and is also positioned just on the side of line a that is opposite to the side of line a occupied by angle 109°.
Therefore, angle x and the angle measure of 109° are alternate exterior angles.
Alternate exterior angles are congruent.
x = 109°.
-8(s+4) = -60
What is the value of s?
Answer:
s = 3.5
Step-by-step explanation:
Lets begin by distributing -8 into the two values in the paranthesis, s and +4. By doing this, we get -8s -32 = -60
We can now take that -32 and bring it to the right side of the equation, making it now -8s = +32 -60
After simplyfing, we now have -8s = -28. Dividing -28 by -8 , we get positive 3.5.

Write an expression for the nth term of...
2,1,0,-1...
Answer:
[tex]a_{n}[/tex] = 3 - n
Step-by-step explanation:
There is a common difference between consecutive terms in the sequence, that is
1 - 2 = 0 - 1 = - 1 - 0 = - 1
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 2 and d = - 1 , thus
[tex]a_{n}[/tex] = 2 - 1(n - 1) = 2 - n + 1 = 3 - n

Step-by-step explanation:
Break it up by asking questions. First, how many 7's fit as a whole into 22:
22 ÷ 7 = 3What is the remainder:
7 × 3 = 2122 - 21 = 1Using the original denominator and our above math, write the mixed number:

in this picture lines AB and CD are parallel. Find the measures of the following angles. Explain your reasoning.
Answer/Step-by-step explanation:
1. <ABC and <BCD are alternate interior angles. Alternate interior angles are equal, therefore, since m<ABC = 38°, then m<BCD = 38°
2. m<ECF = m<BCD (corresponding angles)
m<ECF = 38° (substitution)
3. m<DCF + m<ECF = 180° (linear pair)
m<DCF + 38° = 180° (substitution)
m<DCF = 180° - 38° (Subtraction property of equality)
m<DCF = 142°
The measure of the following angles are as follows;
∠BCD = 38°
∠ECF = 38°
∠DCF = 142°
Angles form when a transversal cut parallel linesWhen a transversal line cut across parallel lines, the angles form include corresponding angles, alternate angles etc.
Therefore,
∠BCD = 38 degrees(alternate angles)
∠ECF = 38 degrees(corresponding angles)
∠DCF = 180 - 38 = 142 degrees(angles on a straight line)

One night a theater sold 548 movie tickets. An Adult’s ticket costs $6.50 and a child’s ticket cost $3.50. In all $2881 was taken in. How many of each kind of ticket were sold?
Step-by-step explanation:
let x be the number of adults and y the number of childrens
x+y=548 people because thats the whole number of sold tickets
and
6.50*x+3.50*y=2881 dollars in total
let separate x from the first formula
x=548-y
and replace it at the second equation
6.50*(548-y)+3.50y=2881
6.50*548-6.50y+3.50y=2881
3562-3y=2881
3y=681
y=227
so x=548-y=548-227=321
there were sold 321 adult tickets and 227 child's tickets.

What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.
Given;
Gianna walked 12 miles in 6 hours
6hours= 12 miles
1hour= 12/6miles
1hour= 2miles
Therefore, the rate of gianna by unitary will be 2mph

What’s the answer??????
Answer:
720 gallons
Step-by-step explanation:
First, find how many gallons are cleaned per hour.
You can use a ratio:
36 gallons = x gallons
1/4 hour 1 hour
Cross multiply:
36 (1) = 1/4x
36 = 1/4x
(36 = 1/4x) (4/1)
144 = x
x = 144
Then, use this info to find how many gallons per 5 hours.
You can use a ratio:
144 gallons = y gallons
1 hour 5 hour
Cross multiply:
144 (5) = 1y
720 = y
y = 720
There are 720 gallons cleaned per 5 hours.

Answer:
Angle A = 65 degrees, Angle B = 78 degrees
Step-by-step explanation:
Since a triangle always has its vertices add up to 180 degrees to be a triangle, we can setup an equation on how to solve it. Adding all the vertices together into a formula to equal 180 degrees gives you 5x-5 = 180. Solving this equation will grant you an answer of x = 37 degrees, and taking this value and plugging it in for each requested angle is how to find the exact degree value. Angle A will just be 2(37) - 9, which ends up to be 65 degrees. Angle B is just 2(37) + 4, which becomes 78 degrees. (You can check the answer by taking all values and adding them together to equal 180. 78 + 65 + 37 = 180.) Hope that helps!
Answer: ∠A = 65° ∠B = 78°
The sum of all interior angles = 180°. So, set 180 equal to the angles you were given (in this case, 2x-9, 2x+4, and x), and solve for x.
180 = (2x-9) + (2x+4) + x (combine the like terms)
180 = 5x - 5 (isolate 5x by moving -5 to the other side)
5x = 180 + 5
5x = 185 (divide both sides by 5 to isolate for x)
x = 37°
Then, sub in the value of x (in this case, 37°) into ∠A and ∠B.
∠A = (2x-9) = 2(37)-9 = 65°
∠B = (2x+4) = 2(37)+4 = 78°
∴ ∠A = 65° and ∠B = 78°.
