# Tyra solves the equation as shown. - 3(x+2) = 9 1. - 3x - 6 = 9 2. - 3x = 15 3. x = - 5 The property Tyra used in line 1 was the: a) associative property b) commutative property c) distributive property d) inverse property

We have been given the equation

The first steps is given as

In this step, Tyra has distributed the term -3 over the parenthesis, as shown below

We know the distributive property is given by

Therefore, we can say that Tyra has used distributive property in the first step.

C is the correct option.

Its the distributive property

It's been estimated that if you consume an extra 3,500 calories, you will gain 1 pound of fat. one can of soda contains 40 grams of sugar. sugar has 4 calories per gram. if a person drinks a six-pack of soda every day, how many pounds will he or she gain in 1 year?

We know that
1 can of soda---------------> 40 grams of sugar
if 1 gram sugar------------------------------------>has 4 calories
40 grams (1 can of soda)-----------------------> X
X=40*4=160 calories
then
1 can of soda--------------> has 160 calories
six-pack of soda every day--------------> 6*160=960 calories every day

in one year------------> 960*365=350400 calories in one year

if 3500 calories----------------> 1 pound of fat
350400 calories----------------X
X=350400/3500=100.11 pound
In one year she or he will gains 100.11 pound of fat

The speed of sound is approximately 340 m / s. How long will it take for the sound to travel from the batter to a spectator who is seated 30 meters away? How long will it take if the spectator is 150 meters away?

The first answer is 3/34 sec and the second answer is 15/34 sec.

Set up a proportion for these problems.  For the first question,
340/1 = 30/x

Cross multiply:
340*x = 1*30
340x = 30

Divide both sides by 340:
340x/340=30/340
x = 30/340 = 3/34

For the second question,
340/1 = 150/x

Cross multiply:
340*x = 150*1
340x=150

Divide both sides by 340:
340x/340 = 150/340
x = 150/340 = 15/34
