Answer:

2x-8

Step-by-step explanation:

Answer:

2x-8

Step-by-step explanation:

If your doing distributive property then you multiply the 2 by the x and the 8 which will give you

2x-8

Answer:

24

Step-by-step explanation:

Given

- a² - (2a - 7b) + b ← substitute a = - 2, b = 3 into the expression

= - (- 2)² - (2(- 2) - 7(3)) + 3

= - 4 - (- 4 - 21) + 3

= - 4 - (- 25) + 3

= - 4 + 25 + 3

= 24

Answer:  32

Steps: -(-2)2  -  [ 2(-2) - 7(3) ]  +  3

• Follow the PEMDAS order of operations

Calculate within parentheses  [ 2(-2) - 7(3) ] :   -25

= -(-2)2 -  (-25)  +  3

Multiply and divide (left to right):  4  -  (-25)  + 3

Add and subtract (left to right):    32

Answer:

1/12

Step-by-step explanation:

-1/3-[-5/12]=?

-1/3-*-5/12=?

-1/3+5/12=

Get the least common multiple:12

-1/3*4/4+5/12*1/1=?

-4/12+5/12=?

1/12

Isolate the variable by dividing each side by factors that don't contain the variable.

Given:

The number of pages she has left to read is 276−35d, where d represents the number of days she has been reading.

To find:

The explanation of each part of the expression.

Solution:

The given expression is

[tex]276-35d[/tex]

Here, 276 is initial number of pages or total number of pages.

d is number of days she has been reading.

-35 represents the remaining pages decreased by 35 per day.

35d is number of pages she reads in d days she has been reading.

Therefore, total number of pages is 276 and number of pages she reads each day is 35.

Step-by-step explanation:

It can be expressed as a ratio

Answer:

36CDs

Step-by-step explanation:

The number of CDs in Walter's collection can be represented by x. The number of CDs in Brian's collection is 3 times the number in Walter's collection.

Hence, Brian's collection = 3x

The total number of CDs in both collections is 144.

We have the Equation:

x + 3x = 144

4x = 144

x = 144/4

x = 36

Therefore, the number of CDs in Walter's collection is 36 CDs

Answer:

36 tickets

Step-by-step explanation:

First you set up your equation, which would be 12 + 0.50x = 30. Next you subtract 12 on both sides to get 0.50x = 18. Divide both sides by 0.50 to get x = 36.

Answer:

x = 0

Step-by-step explanation:

Given

- 4 =  3 + 7(x - 1) ← distribute and simplify right side

- 4 = 3 + 7x - 7

- 4 = 7x - 4 ( add 4 to both sides )

0 = 7x  , then

x = 0

Answer:

The length of h is 3cm.

Step-by-step explanation:

You are looking for h. In order to find h you need the equation of area of a triangle, which is a=1/2bh. They give you base and they give you area. Plugging the numbers in, the equation is 7 7/8 cm^2= 1/2(5 1/4)(h). Now you solve by getting h by itself.

2(7 7/8 cm^2)= (1/2(5 1/4)(h))2

(15 3/4)/(5 1/4)= ((5 1/4)(h))/(5 1/4)

3=h

Answer:

The answer is h+ 3cm

Answer:

2640

Step-by-step explanation:

Yes:No = 7:5

Total votes = 6336

So, 7x+5x = 6336

12x = 6336

x = 6336/12 = 1056/2 = 528

Number of No votes = 5*528 = 2640

Step-by-step explanation:

Answer: The barrel holds about 58.44 gallons of oil .

Step-by-step explanation:

Given : For cylinder , diameter = 22 inches and height = 35.5 inches

radius = 11 inches [half of diameter]

Volume of cylinder  [tex]=\pi r^2h[/tex], where r= radius and h = height.

Volume of cylinder  [tex]=\dfrac{22}{7}\times(11)^2\times 35.5=13500.14\text{ cubic inches}[/tex]

Since, There are 231 cubic inches in a liquid gallon, so.

1 cubic inch = [tex]\dfrac{1}{231}[/tex] gallon.

13500.14 cubic inch = [tex]13500.14\times\dfrac{1}{231}\approx58.44\text{ gallons}[/tex]

Hence, The barrel holds about 58.44 gallons of oil .

Answer:

(-5b+3)(b-1)

Step-by-step explanation:

We need to factorize the given expression

-5b^2+8b-3

-5b^2+5b+3b-3

(-5b^2+5b)+(3b-3)

factor out the common terms:

-5b(b-1)+3(b-1)

(-5b+3)(b-1)

Hence the expression equivalent to -5b^2+8b-3 is (-5b+3)(b-1)
