Answer:

question \:  \:  \: 01 \\ x +  \frac{1}{3}  \\ x =  - 2.5 \\  \\  - 2.5 +  \frac{1}{3}  \\  \frac{ - 7.5}{3}  +  \frac{1}{3} \\   =  \frac{ - 6.5}{3}  = 2.167

Answer for the first question is not there. so,answer is 2.167

question \:  \:  \: 02 \\  \frac{1}{2} (4 - 6y + 8) \\  = 2 - 3y + 4

=6-3y

question \:  \:  \: 03 \\ 3(x + 2) \\ 3x + 6

answers

question 1 = -0.5

question 2 = 6 - 3y

question 3 = 3x + 6

question 1

to evaluate (x + 1)/3 when x = -2.5, plug the value of x into the equation

(x + 1)/3

= (-2.5 + 1)/3

= (-1.5)/3

= -0.5

question 2

to solve this, distribute the 1/2 through the parentheses

(1/2) * (4 − 6y + 8)

= (1/2 * 4) + (1/2 * -6y) + (1/2 * 8)

= 2 + (-3y) + 4

= 6 - 3y

question 3

to solve this, distribute the 3 through the parentheses

3(x + 2)

= (3 * x) + (3 * 2)

= 3x + 6

<em>note - i tried to plug -2.5 into x + (1/3) for question 1, but the answer wasn't among the solutions, so i assumed the equation was (x+1)/3 instead since its answer was among the solutions</em>

A can of soda in 1972 costs $0.15, by 2012 it cost $1.35 find the rate at which the cost of a can of soda increases over this ti
fenix001 [56]

Answer:

800%

Step-by-step explanation:

<h2><u>Percentage increase</u></h2><h3><u>formula:</u></h3>

change/ original * 100

change is 1.35 - 0.15 = 1.2

original is the amount in the beginning which is 0.15

= 1.2/0.15 * 100

=800 %

<em><u>the percentage increase is by 800%</u></em>

39/250 in simplest form
OleMash [197]
Getting the simplest form of a fraction is the same with getting its lowest term. Reducing fractions to its lowest term is a very simple thing to do. Here's how to simplify fractions:

There are two ways in simplifying fractions. The first method is to equally divide both numerator and denominator which results to only whole numbers. Getting the GCF (Greatest Common Factor) or GCD (Greatest Common Divisor) is the second method.

As to the fraction above, 39/250, the second method is applicable.
Let us get the GCF of 39 and 250
39= 1,3,13,39
250= 1, 2, 5,  10, 25, 50, 125, 250

Therefore, the GCF of 39 and 250 is 1. We can conclude then that 39/250 is already on its simplest form thus;
  <u>39</u>  ÷     <u>1</u> is equal to     <u>39</u>
 250       1                       250
