Write an equation that has a solution of 4. Use a variable n and multiplication.

Answer:

False, that would be racism/prejudice.

Answer:

(2.5, -1)

Step-by-step explanation:

The midpoint of a line segment is just the average position of the 2 endpoints.

(x1, y1) = (1, 2)

(x2, y2) = (4, -4)

Find the average x-coordinate by adding them up and dividing by 2:

[tex]\frac{1+4}{2}=\frac{5}{2}=2.5[/tex]

Do the same for the y-coordinate:

[tex]\frac{2-4}{2}=\frac{-2}{2}=-1[/tex]

Using those, the coordinate of the midpoint is (2.5, -1)

Answer:

x=5

Step-by-step explanation:

Formulate and substitute:d=4v

Rearrange unknown terms to the left side of the equation: 4x=27-7

Calculate the sum or difference: 4x=20

Divide both sides of the equation by the coefficient of variable: x=20÷4

Calculate the product or quotient: x=5

So the Answer is: x=5

Answer:

  1 9/40

Step-by-step explanation:

Any calculator can tell you the sum is ...

  1 + 2/16 + 0.6 - 1/2 = 1.225

The decimal fraction can be reduced, if you like:

  225/1000 = (25)(9)/(25(40)) = 9/40

As a mixed number, the sum is 1 9/40.

__

Alternate solution

  1 2/16 + 0.6 -1/2 = 1 1/8 + (6/10 -5/10) = 1 1/8 + 1/10

  = 1 + (1/8 +1/10) = 1 +(5/40 +4/40) = 1 9/40

Step-by-step explanation:

the area of the whole large square is (3x)² = 9x²

when combining 2 shaded triangles they build a small square of x×x or x².

since we have two pairs of such triangles, we have two small squares, and their combined area is x² + x² = 2x²

that means that the whole remaining unshaded area is

9x² - 2x² = 7x²

and so, the ratio shaded/unshaded area is

(2x²)/(7x²) = 2/7

Using the mean concept, it is found that a range of scores between 17 and 53 will give Lisa a C for the semester.

In this problem, we have that:

Hence, the mean is:

[tex]M = \frac{90 + 82 + 91 + x}{4} = \frac{263 + x}{4}[/tex]

For a grade between 70 and 79, we have that:

[tex]70 \leq M \leq 79[/tex]

Then:

[tex]M \geq 70[/tex]

[tex]\frac{263 + x}{4} \geq 70[/tex]

[tex]263 + x \geq 280[/tex]

[tex]x \geq 17[/tex]

[tex]M \leq 79[/tex]

[tex]\frac{263 + x}{4} \leq 79[/tex]

[tex]263 + x \leq 316[/tex]

[tex]x \leq 53[/tex]

A range of scores between 17 and 53 will give Lisa a C for the semester.

Bill's speed is constant after 5 seconds and 45 meters into the race.

Correct responses:

a. Bill's maximum speed is 8 m/s

b. 24 meters

c. 57 meters

Given parameters are;

The distance of the race = 100 meter

Distance at which Bill reaches maximum speed = 45 meters

Speed Bill maintains after 5 seconds = The maximum speed

Time at which Bill is 85 meters from the starting line = 10 seconds after start

a. Required;

Bill's maximum speed in meters.

Solution:

Distance Bill runs at maximum speed, d = 85 m - 45 m = 40 m

Time at which Bill runs the 40 m at maximum speed, t = 10 s - 5 s = 5 s

[tex]Speed = \mathbf{\dfrac{Distance}{Time}}[/tex]

Therefore;

b. i. Required:

The distance Bill will run for 3 seconds at the maximum speed;

Solution:

Distance, s = Speed, v × Time, t

The distance traveled at maximum speed in 3 seconds is therefore;

Distance = 8 m/s × 3 s = 24 m

The distance Bill travels in 3 seconds at the maximum speed is 24 meters.

ii) The distance Bill travels at 8 seconds after start, is given as follows;

Distance traveled in the first 5 seconds = 45 meters

Distance traveled in the next 3 seconds = 24 meters

Therefore;

c. Bill's distance 6.5 seconds after the start of the race is given as follows;

Distance traveled in the first 5 seconds = 45 meters

Distance traveled in the next 1.5 seconds = 1.5 s × 8 m/s = 12 meters

Answer:

Step-by-step explanation:

Answer:

$1332

Step-by-step explanation:

Let p represent the original price.  Then 0.75p = $999, the sale price.

Solve for p by dividing both sides of this equation by 0.75.  

We get:  p = original price = $999/0.75 = $1332

Answer:

$1332

Step-by-step explanation:

So to solve this problem, we set it by the following equation:

X * 0.75 = 999

The reasoning behind that is, we are looking for the originial price's 75%, which is 999. Let X be the original price. So X of 75% = 999. 75% can also be written as 0.75 in the decimal form (75/100).

Solving for X, you divide 999 by 0.75. That'll give you the answer of 1332.

The original price of the computer is $1332.

Answer:

15. UA = 24

16. QW = 9

Step-by-step explanation:

15. since UA = AS, we put an equal sign in between both equations

3x+3=4x−4

Step 1: Subtract 4x from both sides.

3x+3−4x=4x−4−4x

−x+3=−4

Step 2: Subtract 3 from both sides.

−x+3−3=−4−3

−x=−7

Step 3: Divide both sides by -1.

-x/-1 = -7/-1

x = 7

To find UA, we substitute x to 7

UA = 3x + 3

UA = 3(7) + 3

(3)(7)+3

=21+3

=24

UA = 24

To find AS

AS = 4x - 4

AS = 4(7) - 4

(4)(7)−4

=28−4

=24

AS = 24

16. 2x - 1 = x - 4

Step 1: Subtract x from both sides.

2x−1−x=x+4−x

x−1=4

Step 2: Add 1 to both sides.

x−1+1=4+1

x=5

Answer:

x=5

To find QW

QW = 2x - 1

QW = 2(5) - 1

To find WS

WS = x + 4

WS = 5 + 4

5 + 4

= 9

WS = 9
