Achef cooked seven kilograms of mashed potatoes for a dinner
party. if the guests only ate three-quarters of the amount he cooked,
how much did they hurry up

Hence, the amount of potatoes they ate is:

Step-by-step explanation:

A chef cooked seven kilograms of mashed potatoes for a dinner

party.

Now it is given that:

If the guests only ate three-quarters of the amount he cooked,

We have to find the amount they ate?

(  Three-quarters is an amount that is three out of four equal parts of something )

i.e. the guest ate:

3/4 of 7 kg of mashed potatoes.

which is given by:

Hence, the amount of potatoes they ate is:

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
