Answer: -279

Step-by-step explanation:

-129-150= -279

to check

-279+150= -129

Step-by-step explanation:

set that width is x

and length become 2X

P = 2×( X+ 2X )

200 = 6 X

X=33. 3

width = 33.3 inch

length = 66. 6 inch

Answer:

The answer is x=-1/7

Step-by-step explanation:

11-6x-7-8x=6

Combine like terms

11-7-6x-8x=6

4-14x=6

4-4-14x=6-4

-14x=2

To find x divide both sides by -14

-14x/-14=2/-14

x=-1/7

Answer:

The answer would be 17 cm

Step-by-step explanation:

If the distance between their feet is 12 cm, then the distance between their heads would also be 17 cm, because of their five cm height difference. [ You add that on to their normal distance]. I hope this helped! If I'm wrong, I'm sorry and please let me know... Have a great day!!

Answer:

Answer:

c

Step-by-step explanation:

a is not enough information because the measure of angle 2 could be another random value

b is not correct for the same reason as a

d is not correct because those two angles do not equal 90

c is correct because of a theorem, so basically if you have two angles, and they have segments at 90 angles placed in the specified spots,  they are on the bisector

Answer:

 about 7.64 units

Step-by-step explanation:

The volume is given by the formula ...

  V = πr²h

Then the height is ...

  h = V/(πr²) = 1176/(π·7²)

  h ≈ 7.64 . . . . units

Answer:

B. 24 units

Just took the Pre-Test on Edg (2020-2021)!

Answer:

10.285 miles

Step-by-step explanation:

Given that:

Upstream travel time = 5 hours

Return trip travel time = 3.6 hours

Let upstream travel speed = x mph

Downstream travel speed = x + 4 mph

Distance = speed * time

Upstream distance = x * 5 = 5x

Downstream distance = (x + 4) * 3.6

5x = (x + 4) * 3.6

5x = 3.6x + 14.4

5x - 3.6x = 14.4

1.4x = 14.4

x = 10.285714

x = 10.285 miles

Answer:

C

Step-by-step explanation:

Answer:

D.)  y=5x+14

Step-by-step explanation:

point slope form: y-y1=m(x-x1)

y1=4, m=5, x1=-2

y-4=5(x+2)

distribute 5

y-4=5x+10

add 4 to both sides

y=5x+14

Answer:

(49x + 18) + 49y

Step-by-step explanation:

you woud place the variable (letter) representing the number of weeks they worked by the amount they get paid each week then, you would add to whoever gets an extra amount of money, the y - intercept or in this case the extra 18 dollars one of them gets paid to whoever got paid that amount of extra money. :)

Answer:

C( 49x + 18 + 49y)

Answer:

k = 9

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to 8

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 1, 1) and (x₂, y₂ ) = (0, k)

m = [tex]\frac{k-1}{0+1}[/tex] = k - 1 = 8 ( add 1 to both sides )

k = 9

Answer:

$108

Step-by-step explanation:

From the above question, we have the proportion:

Company A/Company B

= $9/$2 = x/x24

The next step is : We Cross Multiply

2x = $24 × $9

x = $24 × $9/2

x = $108

Therefore, she will invest in $108 company A if she invests $24 in company B.

Answer:

you flip 9/2 into 2/9 and then 3/0 multiply across and you get 6/9.

Step-by-step explanation:

Answer:

x=50

Step-by-step explanation:

The best and only represents the equation y = 5x – 8 is done in the table C.

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.

Given a linear equation y = 5x - 8

As we can see that this equation has a slope of 5 and a y-intercept of -8

To ease the process we will calculate the value of y at different values of x:

For x = 0 ,

y = 5 * 0 - 8 = -8

For x = 1

Y = 5-8 = -3

For x = 2

Y = 5*2 - 8

y = 2

For x = 3

y = 5*3 -8

y = 7

for x = 4

y = 20 *8

y = 12

Since only table C is satisfying the situation.

therefore, The best and only represents the equation y = 5x – 8 is done in table C.
