I need help guys.<br>Solve for x<br>y = x-v/b

Airida [17]

You could use the equation y=mx+b

Find the slope of the two coordinates. I would personally suggest using stack and subtract:

(0,2) 2-5 -3 3
(2,5) -------= ------= -----
0-2 -2 2

We have the slope but we need to find the y-intercept.

y=3
--x+b
2

Plug one of the coordinates in the constructed equation above:

2=3
-- (0)+b
2

2=0+b
-0=-0
------------
b=2

We found the slope and y-intercept. Now we have our complete equation. The equation is:

y=3
--x+2
2

Have a blessed day!

36/49 = 5/n find n. will mark for whoever answers

Crazy boy [7]

Answer:

n = 245/36

Step-by-step explanation:

Usually, these are solved in 2 steps:

eliminate fractions by multiplying by the LCM of the denominators
divide by the coefficient of the variable.

Doing that, we have ...

(49n)(36/49) = (49n)(5/n)

36n = 49·5 = 245 . . . . . simplify

n = 245/36 . . . . . divide by the coefficient of n

_____

Another way to do these is to rewrite the proportion with both sides inverted:

49/36 = n/5

Now, all you need to do is multiply by 5.

n = 5(49/36) = 245/36

__

Or, you can do both of the original steps at the same time:

(49n/36)(36/49) = (49n/36)(5/n)

n = (49·5)/36 = 245/36

Rewriting the whole as an Equivalent Fraction

3.1 Subtracting a fraction from a whole

Rewrite the whole as a fraction using 4 as the denominator :

p p • 4
p = — = —————
1 4
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

3.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

p • 4 - (1) 4p - 1
——————————— = ——————

When a fraction equals zero :

6.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

2•(2p-11)
————————— • 4 = 0 • 4
4
Now, on the left hand side, the 4 cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :
2 • (2p-11) = 0

Equations which are never true:

6.2 Solve : 2 = 0

This equation has no solution.
A a non-zero constant never equals zero.

Solving a Single Variable Equation:

6.3 Solve : 2p-11 = 0

Add 11 to both sides of the equation :
2p = 11
Divide both sides of the equation by 2:
p = 11/2 = 5.500

A car travels at 55 mi/h and gets 11km/l of gasoline. How many gallons of gasoline are needed for a 3.0-h trip?

ella [17]

Answer:

6.377 gallons of gasoline are needed for the 3h trip.

Step-by-step explanation:

This problem can be solved by consecutive direct rule of three's.

A rule of three is called direct when the relationship between both measures is direct. It means that as the value one of measures increases, so will the alue of the other measure.

The first step is to know how much the car traveled.

The trip was 3-h long, and the car traveled at 55 mi and hour. So:

1 hour - 55mi

3 hour - x mi

x = 55*3

x = 165 miles

The car traveled 165 miles.

Then we need to know how many kilometers the car traveled.

Each mile has 1.61km, so:

1 mile - 1.61km

165 miles - x km

x = 165*1.61

x = 265.5 km

The car traveled 265.5 km

Now we need to know how many liters the car used

For each liter used, the car can travel 11 km, so:

1L - 11km

xL - 265.5 km

11x = 265.5

$x = \frac{265.5}{11}$

x = 24.14L

The car used 24.14L

The final step is converting from L to gallons.

Each liter has 0.264 gallons, so:

1L - 0.264 gallons

24.14L - x gallons

x = 0.264*24.14

x = 6.377 gallons

6.377 gallons of gasoline are needed for the 3h trip.
