Answer:
x = 25
Step-by-step explanation:
Since these 2 angles are vertical angles, then they are both equal. Set up an equation and then solve it.
75 = 4x - 25
75 + 25 = 4x
100 = 4x
100/4 = 4x/4
25 = x
Hope this helps. Brainly will be highly appreciated.
Answer: The angles are vertical; x = 25.
Step-by-step explanation:
A vertical angle is a pair of opposite angles formed by intersecting lines. As shown in the picture, the lines are opposite and are formed by intersecting lines.
A known fact is that vertical angles are always congruent, meaning they both have the same measure; so, 75 = 4x - 25. Now, let’s solve that equation:
75 = 4x - 25 (add 25 to both sides)
100 = 4x (divide by 4 on both sides)
25 = x
PLS HELPPPPPP i dont know how to do question 17,18,24
Answer:
First, find the area of the surface of the shed. Two walls will have an area of 14 x 8 and two walls will have an area of 18 x 10. We get the equation 2(14x8) + 2(10x8) = 224 + 160 = 384 square feet
Next, divide the square footage of the shed's surface by 250 to find how many gallons of paint are needed. 384/250 = 1.54 gallons of paint (rounded to the nearest hundredth)
For the triangle questions, remember that the area of a triangle is [tex]\frac{(base)(height)}{2}[/tex]

Emmanuels Work:
7(x-2)=91
distribute the 7 by multiplying both x and -2 by it
7x-14=91
add 14 to both sides
7x=105
divide both sides by 7
x=15
Mauricio's Work:
7(x-2)=91
to get rid of the 7 multiplication, divide both sides by 7
x-2=13
add 2 to both sides
x=15
I only know the first one with the method Emmanuel is doing sorry ;(

A swimming pool is 30 yards wide. The pool has lanes for swimming laps. Each lane is 9 feet wide. How many lanes are there?
The number of lanes in the swimming pool is 10
Calculating quantityFrom the question, we are to determine the number of lanes in the pool
From the given information,
The swimming pool is 30 yards wide.
That is,
Width of the pool = 30 yards
Convert to from yard to feet
NOTE: 1 yard = 3 feet
∴ 30 yards = 3 × 30 feet = 90 feet
Also,
Each lane is 9 feet wide
That is,
Width of each lane = 9 feet
Number of lanes in the swimming pool = Width of the swimming pool ÷ Width of each lane
Number of lanes in the swimming pool = 90 feet ÷ 9 feet
Number of lanes in the swimming pool = 10
Hence, the number of lanes in the swimming pool is 10

Step-by-step explanation:
1. Make a proportion. Method: Percent proportion
[tex]\frac{percent}{100} = \frac{part}{whole}[/tex]
2. your proportion should look like this. Note: we don't know how much commission he earned.

3. cross-multiply. Multiply 9 x 9000 and make 100x because we don't know its value yet. Hint: X is our unknown commission.
[tex]9000[/tex] × [tex]9[/tex] = [tex]81000[/tex]
4. set your new proportion.

Answer:
20 units²
Step-by-step explanation:
We can split the polygon into two triangles along the x-axis.
To work out the area of the top triangle, we can do 1/2 × b × h → a = 1/2 × 4 × 4 = 8 units²
To work out the area of the bottom triangle, we can do 1/2 × b × h → a = 1/2 × 4 × 6 = 12 units²
8 + 12 = 20 units²

Sara is taking a test made up of multiple-choice and open-ended questions. The multiple-choice questions have a value of 4 points each, and the open-ended questions have a value of 5 points each. If Sara has already answered 10 multiple-choice questions correctly, which inequality best describes the amount of open-ended questions Sara must answer correctly to earn more than 70 points?
x greater-than 6
x less-than 6
x greater-than 12
x less-than 12
Answer:
To find this, you must find the total number of points Sara has scored already. She has answered 10 multiple choice questions which are 4 points each. This means that Sara has scored 40 points so far.
If Sara wants to score at least 70 points, she needs to score at least 30 more points. To find how many open-ended questions she needs to answer, you need to divide the remaining number of points by the number of points an open-ended question is worth. The number we get will be x.
30/5 = 6
This means Sara must complete at least 6 open-ended questions to score 70. Now, all we have to do is figure out which inequality sign to use. Since Sara wants to score more than 70 points, it should be the "greater than" sign.

A clothing store is having a sale. All items are on sale for 35% off the original price. Create an equation in terms of p, the original price of an item, to show the sale price of an item before any sales tax.
Answer:
P ÷ 35% = X
Step-by-step explanation:
Because P is the original answer, it needs to be divided by 35% because it 35% off, so it would equal X, the original item price discounted.
Hope this helps!
The correct equation in terms of p, the original price of an item, to show the sale price of an item before any sales tax is,
⇒ Sale price = p - 35% of p
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
We have to given that;
A clothing store is having a sale.
And, All items are on sale for 35% off the original price.
Now,
Let the original price of items = p
Then, The sale price is,
Sale price = p - 35% of p
= p - 35p/100
= p - 7p/20
= 13p/20
Thus, The correct equation in terms of p, the original price of an item, to show the sale price of an item before any sales tax is,
⇒ Sale price = p - 35% of p
