The answer is 14 - x.

If she is 14 now, and the question is looking for her age x years ago, it is basically just asking you to subtract x from 14.

It also can't be x - 14, because that means Susie's age is x and the question is asking for her age 14 years ago, and it can't be 14x, because that's 14 multiplied by x.

The answer is 14-x because if she 14, to find out x years less than 14, you would have to subtract x from 14 and the equation for that would be 14-x. :)

Mervin has some cartons of milk. He sold 2/5 of milk in the morning. He sold 3/4 of the remainder in the afternoon. 24 more cart

sergejj [24]

2/5 were sold in the morning. This is equal to 40% of the total. That leaves 60% leftover.

3/4 were sold in the afternoon. This is equal to 75% of the 60% leftover or 45% of the total (.6x.75).

The difference between the two sales is 24 cartons or 5% (45%-40%). If 5% is equal to 24 then you can cross multiply to see what is the equivalent number of cartons out of 100%.

5/100 = 24/x

5x = 24(100)

5x = 2400

x = 480

ANSWER: 480 cartons

Determine the volume of the rectangular prism.<br>

Flauer [41]

Answer:

Step-by-step explanation:

We know the formula for a rectangular prism is length × width × height

We also know all the sides so we can rewrite the formula replacing variables.

The length is 8, the width is 2 $\frac{1}{2}$ and the height is 2 $\frac{1}{2}$

8 × 2 $\frac{1}{2}$ × 2 $\frac{1}{2}$

Multiply which ever way is easy for you. I am just multiplying from left to right.

8 × 2 $\frac{1}{2}$ = 20

20 × 2 $\frac{1}{2}$ = 50

Now we get 50. Before we put our answer as 50, there are two more steps.

First we need to add the measurement unit which is feet or ft

We also need to add ³ since it is volume

<u>50 ft³ is our final answer</u>

PLEASEEEE

Answer:

The answer to your questions is: 25 new teachers

Step-by-step explanation:

Data

# of students = 2000

ratio = 3:80 teachers to students

New teachers = ?

Process

I suggest to use rule of three to solve this problem

3 teachers ---------------- 80 students

x ---------------- 2000 students

x = (2000 x 3) / 80 = 75 teachers

Number of initial teachers = 75

The ratio change to 1:20

1 teacher ------------------- 20 students

x ------------------- 2000 students

x = (2000 x 1) / 20

x = 100 teachers

Number of new teachers = 100 - 75 = 25

Family has an annual income of $23 comma 400. Of this, one fourth

denis23 [38]

Amount spent for food = $5850, housing = $4680, clothing = $2340, savings = $2600, taxes = $5850, expenses = $2080.

<u>Step-by-step explanation:</u>

Step 1:

Given details are Total Income = $23,400

Step 2:

Amount spent for food, F= 1/4th of 23,400 = $1/4 \times 23400$

= $5850

Step 3:

Amount spent for housing, H = 1/5th of 23,400 = $1/5 \times23400$

= $4680

Step 4:

Amount spent for clothing, C = 1/10th of 23,400 = $1/10 \times 23400$ = $2340

Step 5:

Amount spent for savings, S = 1/9th of 13,400 = $1/9\times 23400$ = $2600

Step 6:

Amount spent for taxes, T = 1/4th of 23,400 = $1/4 \times 23400$ =$5850

Step 7:

Find amount spent on other expenses by totaling all expenditures and subtracting from the annual income.

Annual Income = F + H + C + S + T + E

Amount spent on other expenses, E = 23400 - (5850 + 4680 + 2340 + 2600 + 5850)

E = 23400 - 21320

E = $2080
