It is a trick question. multiply 5.5 times 0.75=4.125
You multiply the number outside the parenthesis with both of the numbers in the parenthesis separately.
Use the slope formula below:

To form an equation of a line - we need to find a slope and the y-intercept from y = mx+b. We are given two points which we can substitute in the formula.

We have finally got the slope. Next is to find the y-intercept. First we rewrite the equation of y = mx+b by substituting the slope.

The equation above is the slope-intercept form. Substitute m = -7/6 in the equation.

Since the graph passes through (0,0) which is an origin point. In y = mx+b if the graph passes through origin point, that means the b-value is 0. Therefore:

Answer:
25
Step-by-step explanation:
If we call the number we're looking for n, then
n * 60/100 = 15
then n = 15/0.6 = 25
To solve, the first step is to find the LCM (least common denominator). In this scenario, it's ten.
6 5/10 - 2 3/10
From here, do the math. It's easy this time, what's 5 - 3? Two.
Now, subtract two from six. (four)
4 and 2/10
4 and 1/5
There! :)
