First, make sure that all the variables are in one side. The first equation is gonna be x-y=3

Second, we are going to eliminate the y because it is much easier, but you can also eliminate the x

We have to add both equation because the y in the first equation is negative and in the second equation it’s positive.

We are left with 3x=9

Therefore, x=3

Last, substitute x= 3 in one of the equations

Y=6

P.O.I is (3,6)

iren [92.7K]

Answer: x = 60

Step-by-step explanation:

the equation is a^2 + b^2 = c^2.

If you draw out the problem, you plug in the information into the formula, so it would be...

x^2 + 80^2 = 100^2.

80^2 = 6,400 and 100^2 = 10,000.

x^2 + 6,400 = 10,000.

You subtract 6,400 from itself and 10,000 and then you get...

x^2 = 3,600.

You square both of those and your final answer will be x = 60.

Darya [45]

Answer:

4.8 Liters

Step-by-step explanation:

Sundaes at her next birthday party. She thinks each person will eat 200 milliliters of ice cream, and there will be 24 people at her party. How many liters of ice cream should she buy

Step 1

1 person = 200ml of ice cream

24 persons = x

Cross Multiply

x = 24 × 200ml of ice cream

x = 4800 ml of ice cream

Step 2

How many liters of ice cream should she buy

We convert from Milliliters to Liters

1 milliliters= 0.001 liters

4800 millilitres = x

Cross Multiply

= 4800 × 0.001 liters

= 4.8 Liters

Therefore, she should buy 4.8 Liters of ice cream
