Step-by-step explanation:
first you need to find the other angle. to do so do 180-135=45
so you know 2 angles now. 35° and 45°. Add these angles (you get 80°)
then 180-80=100

Answers
Answer:
The tectonic plates.
Step-by-step explanation:
If you look at a diagram of Earth on Google, you'll see there's the crust, the mantle, the core...etc. If the tectonic plates are apart of the crust- which is the Earth's surface, then it's safe to assume the shell of the egg is the tectonic plates.

Answer:On a coordinate plane, a straight line with a positive slope crosses the x-axis at (negative 1, 0) and crosses the y-axis at (0, 5)
Step-by-step explanation:
(f + g)(x) = -x² + 3x + 5 + x² + 2x = 5x + 5
=> y = 5x + 5
=> the slope is positive
the line crosses the x-axis at (-1;0) and the y-axis at (0;5)

Find the GCF of the given polynomial. 16a^4b^4 + 32a^3b^5 - 48a^2b^6
Answers
Answer:
[tex]16a^2b^4[/tex]
Step-by-step explanation:
GCF= Greatest Common Factor
Given a polynomial, the GCF is the largest polynomial that will divide evenly into that polynomial.
The polynomial is
[tex]16a^4b^4 + 32a^3b^5 - 48a^2b^6[/tex]
First, we find the GCF of the coefficients:
16, 32, 48
Since 32 and 48 are multiples of 16, 16 is the GCF of the coefficients.
Now we select all the repeating variables with their smallest exponent:
[tex]a^4, a^3, a^2.\ GCF= a^2[/tex]
[tex]b^4, b^5, b^6.\ GCF=b^4[/tex]
The GCF of the polynomial is

Step-by-step explanation:
Since the graph is facing down, We know the equation is y<mx+b
Since slope is rise/run the slope is 1/3.
Since the y intercept (The point where the line hits y) is 1, the equation is
y<1/3x+1

The line is solid meaning that we have to include the line as part of the values. This will make the new equation

Megan's commute to work includes an 8-mile drive and a 21-mile train ride. This expression can be used to find the total time it takes Megan to get to work, where xis her average driving speed in miles/hour. 21
Answers
Answer:
(8 / x) + (21 / y)
Step-by-step explanation:
Given that:
Average driving speed = x mph
Miles driven to work = 8 mile
Miles by train to work = 21 miles
Average train speed = y
Total time taken to get to work. :
Recall : time taken = distance / speed
Hence,
Time taken =) total distance / average driving speed)
Total time taken = (8 / x) + (21 / y) hours
Total time taken = (8 / x) + (21 / y) hours
Answer: The average speed of the train is represented by x+20. When Megan drives at an average speed of 45 mph, it takes her approximately 0.50 hour to get to work.

x –12 = -8x + 6 a.x = 2 b.x = -2 c.x = 3 d.x = -3
Answers
Answer:
(a) x = 2
Step-by-step explanation:
x - 12 = -8x + 6
First, move all the like terms to one side of the equation. We will move all the x's to the left, and the rest to the right in this equation. (Don't forget to pay attention to the signs of the numbers as you move them over the equal sign.)
x - 12 + 8x = 6
x + 8x = 6 + 12
9x = 18
Next, solve for x by isolating it to one side of the equation. Here, we'll have to divide 18 by 9 (do the opposite of what 9 is doing with x; instead of multiplying it with 18 like it currently is with x, divide 18 by it.)
x = [tex]\frac{18}{9}[/tex]
x = 2
Therefore, your answer is (a), since x = 2.

Prove that Triangle abc and Triangle edc are similar
Answers
The corresponding sides have equal ratios, so the triangles are similar triangles.
From the question, we have:
In triangle ABC, AB = 3, BC = 5 and AC = 4
In triangle EDC, ED = 9, DC = 15 and EC = 12
For the triangles to be similar, then the corresponding sides must have an equivalent ratio.
This is calculated as:
[tex]\mathbf{Ratio = \frac{ED}{AB} = \frac{DC}{BC} = \frac{EC}{AC}}[/tex]
So, we have:
[tex]\mathbf{Ratio = \frac{9}{3} = \frac{15}{5} = \frac{12}{4}}[/tex]
[tex]\mathbf{Ratio =3 = 3 = 3}[/tex]
[tex]\mathbf{Ratio =3}[/tex]
Because the corresponding sides have equal ratios, then the triangles are similar.

Last season, a pair of jeans cost $42.95. This season, the price of the jeans increased by 25 percent. Later in the season, the jeans were put on sale for 25 percent off. First, guess. What do you think the sale price will be? Why? Then, calculate: How much did the jeans cost at the beginning of this season? What was their sale price? Did you get the sale price you were expecting? Why or why not? Consider what the jeans would cost if they had gone on sale by 25% first, and then had their price increased by 25%. First guess. What do you think the jeans will cost this time? Why? Then, calculate: How much will the jeans cost this time? Did you get the answer you were expecting? Why or why not?
Answers
Answer:
42.95 first price hiked 25%, then discounted by 25% : Final price = 40.28
42.95 first discounted by 25%, then price hiked by 25% : Final price = 40.27
Both are same (approx) because of same mathematical treatment
Step-by-step explanation:
If Jeans price first hiked price by 25%, then gone on sale by 25%Last season price = 42.95
This season increase in price = 25% of 42.95 = 10.73
Jeans price at beginning of this season = 53.68
Discount on sale price, this season = 25% of 53.68 = 13.42
Discounted jeans price this season = 53.68 - 13.42 = 40.28
If Jeans price first gone on sale by 25%, then price increased by 25%Last season price = 42.95
Discount on previous price = 25% of 42.95 = 10.73
Jeans price this season = 42.95 - 10.73 = 32.22
Price hike this season = 25% of 32.22 = 8.05
New jeans price this season = 32.22 + 8.05 = 40.27
The same answer is got in both cases. As, mathematically, they are same. 1st : 75% of (125% of 42.95) & 2nd : 125% of (75% of 42.95)What is 6/5 divided by 4/3

What is the Distributive property?Distributive law, also called distributive property, in mathematics, the law relating the operations of multiplication and addition, stated symbolically as a(b + c) = ab + ac; that is, the monomial factor a is distributed, or separately applied, to each term of the binomial factor b + c, resulting in the product ab + ac.
