Answer:

x = -7/5

Step-by-step explanation:

Given the equation

(4-8x+5) - (-33x - 26) = 0

To get variable x, we will open the bracket first

9-8x + 33x + 26 = 0

35+25x = 0

35 = -25x

x = -35/25

x = -7/5

Brady is selling candy bars for a school fundraiser to help pay for new sports uniforms. He gets paid $2 for every candy bar he

swat32

Answer:

Second option: $2x=90$

Step-by-step explanation:

Let be "x" the number of candy bars Brady sold on Saturday.

For this exercise you need to analize the information provided in the exercise.

According to the information provided, Brady gets paid $2 for every candy bar he sells. This can be expressed as:

$2x$

You know that Brady made a total of $90 on Saturday; this mean the product of $2x$ is 90.

Based on this, you can write the following equation that represents the number of candy bars Brady sold on Saturday:

$2x=90$

Observe that this matches with the second option.

Which of the following represents the inequality for the sum of 11 and y is greater than -33? O11-y> -33 O 11+ y -33 11 + y 2

laiz [17]

Answer:

11 + y > - 33

Step-by-step explanation:

To represent the expression :

Sum of 11 and y ; greater than - 33

Sum of 11 and y ; 11 + y

Greater Than - 33; > - 33

Hence ;

11 + y > - 33

Given the function f(x) = 3|x – 2| + 6, for what values of x is f(x) = 18?

Gwar [14]

Answer:

x = - 2, x = 6

Step-by-step explanation:

Given f(x) = 18 we require to solve

3 | x - 2 | + 6 = 18 ( subtract 6 from both sides )

3 | x - 2 | = 12 ( divide both sides by 3 )

| x - 2 | = 4

The absolute value function always returns a positive value, however, the expression inside can be positive or negative, thus

x - 2 = 4 ( add 2 to both sides )

x = 6

- (x - 2) = 4

- x + 2 = 4 ( subtract 2 from both sides )

- x = 2 ( multiply both sides by - 1 )

x = - 2

As a check substitute these values into the left side of the equation and if equal to the right side then they are the solutions

x = 6 → 3|6 - 2| + 6 = 3|4| + 6 = 3(4) + 6 = 12 + 6 = 18 ← True

x = - 2 → 3|- 2 - 2| + 6 = 3|-4| + 6 = 3(4) + 6 = 12 + 6 = 18 ← True

Hence solutions are x = - 2, x = 6

How many complete rotations will the bowling ball make if it rolls straight down the center of the entire length of the lane. A.

jasenka [17]

<h3>Answer: C) 26 complete rotations</h3>

===========================================

Explanation:

The diameter of the ball is 8.5 inches. So d = 8.5

The circumference of the circle with this diameter is

C = pi*d

C = pi*8.5

C = 8.5pi

C = 26.7035375555132 approximately.

This is the rough distance it travels in one revolution or one full rotation.

--------------

1 revolution = 26.7035375555132 inches

(1/26.7035375555132) revolution = 1 inch

1 inch = (1/26.7035375555132) revolution

1 inch = 0.03744822190398 revolution

There are 12 inches a foot, so,

1 inch = 0.03744822190398 revolution

12*1 inch = revolution

12 inches = 0.44937866284776 revolution

1 foot = 0.44937866284776 revolution

Now multiply both sides by 60

1 foot = 0.44937866284776 revolution

60*1 foot = 60*0.44937866284776 revolution

60 feet = 26.9627197708657 revolutions

Round down to the nearest whole number to get 26

We can't round to 27 even though we're really close to it. This is because we are looking for the number of whole revolutions the ball makes.

Therefore, 60 linear feet correspond to 26 full rotations of the ball. There's a bit leftover, but it's not enough to make another full rotation.
