Kilo means 1000 so 1 kiometer=1000 meter
so every 1000 meter=1 kilometer
to convert,, just divide meters by 1000 and get km
2950/1000=2.95km

Solve for x.<br> 0.9(5x+4) = 5.7 2.5X

Alenkinab [10]

Answer:

x=0.369231

Step-by-step explanation:

0.9(5x+4)=5.7(2.5x)

Step 1: Simplify both sides of the equation.

0.9(5x+4)=5.7(2.5x)

(0.9)(5x)+(0.9)(4)=5.7(2.5x)(Distribute)

4.5x+3.6=14.25x

Step 2: Subtract 14.25x from both sides.

4.5x+3.6−14.25x=14.25x−14.25x

−9.75x+3.6=0

Step 3: Subtract 3.6 from both sides.

−9.75x+3.6−3.6=0−3.6

−9.75x=−3.6

Step 4: Divide both sides by -9.75.

−9.75x/ −9.75 = −3.6/ −9.75

x=0.369231

L 5.2.3 Quiz: Two-Variable Systems: Substitution

Misha Larkins [42]

Answer:

We get x=3 and y=21

The ordered pair will be: (3,21)

Step-by-step explanation:

We need to use the substitution method to solve the system of equations.

$y = 10x-9\\y = x + 18$

For substitution method we substitute the value of x or y from one equation to other.

Let:

$y = 10x-9--eq(1)\\y = x + 18--eq(2)$

Putting value of y from equation 2 into equation 1

$y=10x-9\\Put\:y=x+18\\x+18=10x-9\\x-10x=-9-18\\-9x=-27\\x=\frac{-27}{-9}\\x=3$

So, we get value of x=3

Now, for finding value of y, We substitute the value of x

Find value of x from equation 2

$y=x+18\\x=y-18$

Now, putting value of x in equation 1

$y=10x-9\\Put\:x=y-18\\y=10(y-18)-9\\y=10y-180-9\\y-10y=-189\\-9y=-189\\y=\frac{-189}{-9}\\y=21$

So, we get value of y=21

So, We get x=3 and y=21

The ordered pair will be: (3,21)
