Answer: 87\frac{3}{4}

Step-by-step explanation:

5\frac{1}{4} x 3 = 21/4 x 3 = 63/4 = 15\frac{3}{4}

5\frac{2}{4} x 2 = 22/4 x 2 = 22/2 = 11

6\frac{1}{4} x 5 = 25/4 x 5 = 125/4 = 31\frac{1}{4}

1\frac{1}{4} x 2 = 29/4 x 2 = 29/2 = 14\frac{2}{4}

7\frac{1}{2} x 1 = 7\frac{1}{2}

7\frac{3}{4} x 1 = 7\frac{3}{4}

15\frac{3}{4} + 11 + 31\frac{2}{4} + 14\frac{2}{4} + 7\frac{2}{4} + 7\frac{3}{4} = 85\frac{11}{4} = 87\frac{3}{4}

Answer:

Total = 87\frac{3}{4}

Step-by-step explanation:

Given

See attachment

Required

Total number of distance

This is calculated by multiply each distance by its frequency.

The number of dots represents the frequency

On the line plot, the interval between adjacent points is 0.25.

So, the total distance is:

Total =5.25 * 3 + 5.5 * 2  + 6.25 * 5 + 7.25 * 2 + 7.5 * 1 + 7.75 * 1

Total =87.75

or

Total = 87\frac{3}{4}

Solve the following expression when<br> t = 3 and s = 2<br> (12t) = (6s)<br> Enter
larisa86 [58]

From the solution of the expression, it can be seen that s = 6 when t = 3 while t = 1 when s = 2.

<h3>How do we solve a mathematical expression?</h3>

Given:

(12t) = (6s) ........................ (1)

When t = 3, we can solve for s from the expression in equation (1) by substituting t = 3 into the equation as follows:

12 * 3 = 6s

36 = 6s

s = 36 / 6

s = 6

When s = 2, we can solve for t from the expression in equation (1) by substituting s = 2 into the equation as follows:

12t = 6 * 2

12t = 12

t = 12 / 12

t = 1
