Answer 2

Answer:

x= 72.72 (with a line over it)

Step-by-step explanation:

(x - 5) + (1.4x) + (x) + (x + 35) = 360

Step 1. Simplify both sides of the equation.

x + 5 + 1.4x + x + x + 36 = 360

(x + 1.4x + x + x) + (5 + 35) = 360 (combine like terms)

4.4x + 40 = 360

Step 2. Subtract 40 from both sides.

(4.4x + 40) - 40 = (360) - 40

4.4x = 320

Step 3. Divide both sides by 4.4

4.4x/4.4 = 320/4.4

x = 72.72 (72 repeats, so 72 with a line over it)

A spinner is divided into sections of equal size, of which some are red, some are blue, and the remaining are green. The probability of the arrow landing on a section colored red is 20%. The probability of the arrow landing on a section colored blue is 10%. What is the probability of the arrow landing on a section colored green?

Answers

The probability Would Be 1/5

Answer:

70%

What is given: 20% of one color, and 10% of another.

That gives us 30% of 100%.

Take away the smaller percentage from the limit, which would be 30 from 100.

You are left with 70%, which means that 20% is red, 10% is blue, and 70% is green.
