ruth uses three quarter of floor of a bag to make a cake .workout number of bags of flour she needs to buy to make 7 cakes

5.25

Step-by-step explanation:

She uses 3/4 for one cake, so the ration is 3/4 : 1

If she wants to make 7, you just time 3/4 by 7.

Doing that, we get 21/4 and that equals 5.25.

Ruth needs 5.25 bags of flours to make 7 cakes.

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

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.
