Answer:

3x+10

Step-by-step explanation:

So you're going to want to count the amount of X's their are (3) and put them together (3x). Then to simplify the expression, add the 5+5 together, since they are they same type of variables. Now, you put everything together (3x+10).

A new movie is released each year for 8 years to go along with a popular book series. Each movie is 5 minutes longer than the la

Georgia [21]

Answer:

The total length of all 8 movies is 740 minutes

Step-by-step explanation:

* Lets revise the arithmetic series

- In the arithmetic series there is a constant difference between

each two consecutive numbers

- Ex:

# 2 , 5 , 8 , 11 , ………………………. (constant difference is 3)

# 5 , 10 , 15 , 20 , ………………………… (constant difference is 5)

# 12 , 10 , 8 , 6 , …………………………… (constant difference is -2)

* General term (nth term) of an Arithmetic series:

- If the first term is a and the common diffidence is d, then

U1 = a , U2 = a + d , U3 = a + 2d , U4 = a + 3d , U5 = a + 4d

So the nth term is Un = a + (n – 1)d, where n is the position of the

number in the series

- The formula to find the sum of n terms is

Sn = n/2 [a + l] , where l is the last term in the series

* Lets solve the problem

- A new movie is released each year for 8 years to go along with a

popular book series

∴ n = 8

- Each movie is 5 minutes longer than the last

∴ d = 5

- The first movie is 75 minutes long

∴ a = 75

- To find the total length of all 8 movies find the sum of the 8 terms

∵ Un = a + (n - 1)d

∵ The last term l is u8

∵ a = 75 , d = 5 , n = 8

∴ l = 75 + (8 - 1)(5) = 75 + 7(5) = 75 + 35 = 110

∴ l = 110

∵ Sn = n/2 [a + l]

∴ S8 = 8/2 [75 + 110] = 4 [185] = 740 minutes

* The total length of all 8 movies is 740 minutes

Christopher plays quarterback for a

jeka94

Answer:

70%

Step-by-step explanation:

$42\div60$

Calculate

$\frac{42}{60}$

Cross out the common factor

$\frac{7}{10}$

Multiply a number to both the numerator and the denominator

$\frac{7}{10}\times\frac{10}{10}$

Write as a single fraction

$\frac{7\times10}{10\times10}$

Calculate the product or quotient

$\frac{70}{10\times10}$

Calculate the product or quotient

$\frac{70}{100}$

Rewrite a fraction with denominator equals 100 to a percentage

$70$ %

I hope this helps you

The shape on the left is translated to the shape on the right.

Angelina_Jolie [31]

Answer:

Step-by-step explanation:

Translation means moving so when saying Translate to the right your really moving it to the right. The questions says The shape on left is the original and the right is translated which means the left is the pre-image while right is the image. A is the only answer that doesn’t say the right is the pre image. Also, “ ‘ “ is used to distinguish the pre image coordinates vs the image coords so it easier.
