The average number of students per class at a middle school
Tasya [4]

Answer:

s = 22t or \frac{t}{s} = \frac{1}{22}, when s is students and t is teachers.

Step-by-step explanation:

I. Given t = teacher, s = student

When 1 teacher per 22 students so...

        s = 22t

If there're 10 teachers

        s = 22(10)

           = 220 or \frac{t}{s} = \frac{1}{22}

Hope that help :)

. The cost of 2 pizzas and 1 burger is ₹ 450. Write a linear equation for this situation and draw its graph.​
Akimi4 [234]

Answer:

The linear equation is;

Y = 450 - 2·X

Please find the included graph

Step-by-step explanation:

Whereby we have the following relation;

The cost of 1 pizza = X

The cost of 1 burger = Y

Hence;

450 = Y + 2·X

Which gives;

Y = 450 - 2·X

The linear equation for the situation is therefore as presented above

The graph of the linear equation can be plotted using the assumed data as follows;

Y,           X

1,           448

2,          446

3,         444

4,          442

5,          440

6,          438

7,          436

8,          434

9,          432

10,          430

11,          428

12,          426

13,          424

14,          422

15,          420

16,            418

Margo freezes 8 cups of strawberries if this is 2/3 of the total strawberries that she picked how many cups of strawberries did
Goryan [66]

Answer:

12 cups.

Step-by-step explanation:

Let x be the total cups of strawberries picked by Margo.

We have been given that Margo freezes 8 cups of strawberries and this is 2/3 of the total strawberries that she picked.

We need to find x such that 2/3 of x equals 8. We can represent this information in an equation as:

\frac{2}{3}x=8

Let us multiply both sides of our equation by 3.

3*\frac{2}{3}x=3*8

2x=24

Let us divide both sides of our equation by 2.

\frac{2x}{2}=\frac{24}{2}

x=12

Therefore, Margo picked 12 cups of strawberries.
