The distance is 52.5 cm when weight is 7kg

Step-by-step explanation:

Distance is 15 cm when weight is 2 kg

We need to find the distance d when weight is 7 kg

Since distance and weight varies directly so,

\frac{15}{2}=\frac{d}{7}

Solving the above expression:

\frac{15}{2}=\frac{d}{7}\\Cross\,\,multiply\\15*7=d*2\\105=d*2\\d=\frac{105}{2}\\d=52.5

So, The distance is 52.5 cm when weight is 7kg

What is the length of LN?
nlexa [21]

Find the length of MN by setting up a ratio:

Let MN =  X

X/18 = 5/6

Cross Multiply:

6x = 90

Divide both sides by 6:

x = 15

Now you know MN add it to LM for the total length of LN:

15 + 5 = 20

The sum of three consecutive is 267. What is the largest integer
Oliga [24]
Consecutive means in order. So let's call the first integer x. The next number in line would be x+1 and the largest integer would be x+2. Let's prove that so you're not confused.  If x is 3, then x+1 is 4 (next in line), and x+2 is 5 next after that. See? So if we add all those together we set them equal to 267 and solve for x: x + x+1 + x+2 = 267.  Combining like terms gives us 3x + 3 = 267 and 3x = 264. Now dividing both sides by 3 we get that x = 88.  That's the smallest integer; the largest is found by adding 88 + 2 which is 90.  So that means that the numbers are 88, 89, 90, and that adding them up = 267. Let's check that now: 88+89+90=267 so we're good.

What is the slope of the line that passes through (-3,-7) and (1,9)
Rus_ich [418]

To find slope, use the formula:

(y2-y1)/x2-x1)

So here is what it will look like:

(9--7)/(1--3)

Since you are subtracting a negative, then it turns unto a positive so you are adding the numbers together.  

(9+7)/1+3)

16/4

4

The slope of the line is 4/1 or 4.  Which means that you will go up or "rise" 4 and go to the left or "run" 1.


Hope this helps!

Write the equation of a line that goes the through the point (4 , -2) and is parallel to the line y = 3x - 1/3.
nataly862011 [7]

Answer:

y = 3x - 14

Step-by-step explanation:

If a line is parallel to another, it will have the same slope

So, the line's slope will be 3

Plug in the given point and the slope into y = mx + b, and solve for b

y = mx + b

-2 = 3(4) + b

-2 = 12 + b

-14 = b

Plug in the slope and b into y = mx + b

y = 3x - 14

So, the equation is y = 3x - 14
