Karli's shadow is 60inches long. A nearby fire hydrant cast a shadow 40inches Long. If Kali is 48 inches tAll what is the height

Naily [24]

This question involves ratios.You will use them as fractions.

60:40

48:x

You will need to solve for x, so make fractions.

60/48 = 40/x

Now you'll cross multiply:

1920 = 60x

Divide both sides by 60.

1920/60 = 32.

The fire hydrant is 32 inches tall.

Answer: OPTION B.

Step-by-step explanation:

Given the following System of equations:

$\left \{ {{3x-5y=19} \atop {x+y=1}} \right.$

You can use the Elimination Method to solve it. The steps are:

1. You can mutliply the second equation by -3.

2. Then you must add the equations.

3. Solve for the variable "y".

Then:

$\left \{ {{3x-5y=19} \atop {-3x-3y=-3}} \right.\\.....................\\-8y=16\\\\y=\frac{16}{-8}\\\\y=-2$

4. Now that you know the value of the variable "y", you must substitute it into any original equation.

5. The final step is to solve for "x" in order to find its value.

Then:

$x+(-2)=1\\\\x=1+2\\\\x=3$

Therefore, the solution is:

$(3,-2)$
