Decimals and fractions

Given the expression solved by Keira as;

123.52/3.2

Convert the decimals to fractions

123.52 = 12352/100

3.2 = 32/10

Substitute

123.52/3.2 = 12352/100÷ 32/10
123.52/3.2 = 12352/100 × 10/32

123.52/3.2 = 12352/320
123.52/3.2 = 38.6

Hence the solution to the quotient of  123.52 by 3.2 is 38.6

Tom bought 9 new baseball trading cards to add to his collection. The next day his dog ate half of his collection. There are now only 28 cards left. How many cards did Tom start with ?

Answers

Tom started with 47 cards.

He had 28 left. If his dog ate half then multiply 28 by 2

You get 56

Out of those 56 cards, 9 of them are new

So subtract 9 from 56

You get 47

Tom started with 47 cards

28+28=56

9 are new so 56 - 9 = 47 which is your answer

the equation for the triangle can be this

2(2x+3)+10x-5 = 180

Answer:

x= 16

x=1.5

Step-by-step explanation:

Simplifying

3x + -0.5 = 0

Reorder the terms:

-0.5 + 3x = 0

Solving

-0.5 + 3x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '0.5' to each side of the equation.

-0.5 + 0.5 + 3x = 0 + 0.5

Combine like terms: -0.5 + 0.5 = 0.0

0.0 + 3x = 0 + 0.5

3x = 0 + 0.5

Combine like terms: 0 + 0.5 = 0.5

3x = 0.5

Divide each side by '3'.

x = 0.1666666667

Simplifying

x = 0.1666666667

Simplifying

2x + 3 = 0

Reorder the terms:

3 + 2x = 0

Solving

3 + 2x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3' to each side of the equation.

3 + -3 + 2x = 0 + -3

Combine like terms: 3 + -3 = 0

0 + 2x = 0 + -3

2x = 0 + -3

Combine like terms: 0 + -3 = -3

2x = -3

Divide each side by '2'.

x = -1.5

Simplifying

x = -1.5
