1,250 feet. 2 kilometers to meters is 2000 meters. subtract 750 from that and your answer is 1250 feet.

Answer:

Adrian lives closer to the school by A. 1,250 meters.

Step-by-step explanation:

1 kilometer = 1,000 meters

So, if Kevin's home is 2 kilometers from the school, then it is also 2,000 meters away, since  1,000 x 2 = 2,000.

Adrian lives 750 meters, or 0.75 kilometers away from school.

2,000 - 750 = 1,250.

Therefore, Adrian lives closer to the school by A. 1,250 meters.

Answer:

1/2

Step-by-step explanation:

remember that the formula for the slope of a line is

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

where m is the slope, and the x and y variables are the x-y coordinates of two points. Choose two points on the line:

Point 1 : (-1,3) and Point 2 : (1,4)

Plug in your values:

[tex]m=\frac{4-3}{1-(-1)}[/tex]

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

So the slope of this line is 1/2 !

Answer: The slope is [tex]\frac{1}{2}[/tex].

The extraneous solution is 6. First square the right side of the equation, then solve. You get 6. Since when you plug in 6 to the equation, it does not add up to the same value on both sides, then it is extraneous.

solve for x- 5(x+4)=30​

Answers

Answer: x= -12.5

Step-by-step explanation:

Start with distributing-5(x+4) or you get

x-5x-20=30

Add x and -5x to get -4x

Thank you add 20 to each side and get

-4x = 50

Divide by -4 on each side to get x=-12.5

Answer:

x=-25/2 is the answer.

Step-by-step explanation:

Below are the steps for solving the equation:

Step 1: Simplify, combine like terms, and distribute:

x−5(x+4)=30

x+(−5)(x)+(−5)(4)=30

x+−5x+−20=30

(x+−5x)+(−20)=30

−4x+−20=30

−4x−20=30

Add 20 to each side:

−4x−20+20=30+20

−4x=50

Divide each side by -4:

-4x/-4=50/-4

x=-25/2, which is -12.5 as a decimal.

So, your answer is x=-25/2 as a fraction, which is also -12.5 as a decimal.

5) The height of a rocket after it is launched

For this case, what you should do is remember the kinematics expressions where we have:

v = a * t + vo

y = a * t ^ 2 + vo * t + i

Where,

a: acceleration

v: speed

y: vertical position

t: time

vo: initial speed

We observe that the expression for the given position is given by a quadratic expression.

8 is what percent of 64?

Answers

Answer:

The answer is 12.5

8 is 12.5 percent of 64
Steps:

8:64*100 =

( 8*100):64 =

800:64 = 12.5
All the steps:

Now we have: 8 is what percent of 64 = 12.5

Question: 8 is what percent of 64?

Percentage solution with steps:

Step 1: We make the assumption that 64 is 100% since it is our output value.

Step 2: We next represent the value we seek with x.

Step 3: From step 1, it follows that %100=64

Step 4: In the same vein, x%=8.

Step 5: This gives us a pair of simple equations:
%100=64(1)
x%=8(2)

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have

100%/x% = 64/8

Step 7: Taking the inverse (or reciprocal) of both sides yields

x%/100% = 8/64

x =12.5%
Therefore, 8 is 12.5% of 64.
