maks197457 [2]

Answer:

Amrita's number is 6

Step-by-step explanation:

x               Double the unknown number

2x             Add 9

2x + 9       Divide the answer by 3

2/3x + 3   Subtract 1

2/3x + 2   Set this equal to the original number

2/3x + 2 = x

-2/3x       -2/3x   Subtract 2/3x from both sides

2 = 1/3x   Multiply both sides by 3

6 = x

notsponge [240]

1 pound of macadamia nuts; 3 pounds of almonds of each nut will she use.

Given that,

Sheri is making 4 pounds of mixed nuts.

She will use One-third the number of macadamia nuts as she does almonds.

A graph titled Sheri's mixed nut recipe has pounds of macadamia nuts on the x-axis, and pounds of almonds on the y-axis. 2 lines intersect at (1, 3).

We have to find,

How many pounds of each nut will she use?

According to the question,

Total mixed nuts are 4 pounds,

She will use One-third the number of macadamia nuts as she does almonds.

2 lines intersect at (1, 3).

Therefore,

Sheri's mixed nut recipe has pounds of macadamia nuts on the x-axis,

At x-axis, the point 1 lies.

So, macadamia nuts have 1 pound.

And pounds of almonds on the y-axis,

At y-axis, the point 3 lies.

So, almond nuts have 3 pounds.

Hence, 1 pound of macadamia nuts; 3 pounds of almonds of each nut will she use.

Dominik [7]

Answer:

Step-by-step explanation:

Let d represent the total number of days that the milk will last.

The total number of cat warriors travelling together is 8. Each cat needs 4 liters of milk per day to maintain good morale. This means that the 8 cat warriors would need

8 × 4 = 32 liters of milk.

Let n represent the total number of liters of milk available. Therefore, the total number of days the milk will last, d would be

d = n/32

Mirri has a supply of 96 liters of milk. Another cat has enough milk to last for 2 days. This means that the amount of milk that the cat has is 4 × 2 = 8 liters. Total amount of milk available would be

96 + 8 = 104 liters

Therefore

d = 104/32 = 3.25 days
