Norma-Jean [14]

Answer:

1. False 2. False 3. True 4. False 5. True

Step-by-step explanation:

Given:

Fred bought 4 liters of liquid laundry detergent,

3,260 millilitres of fabric softener, and

2.3 liters of bleach.

Select true or false for each statement.

1. Fred bought 96 millilitres more fabric softener than bleach.

Solution:

Fred bought fabric softener = 3,260 millilitres

Fred bought bleach = 2.3 liters = 2300 millilitres

1 liter = 1000 millilitres

2.3 liter = 1000 $\times$ 2.3 = 2300 millilitres

Fred bought more fabric softer than bleach = 3,260 - 2300 = 960

Hence, it is false and actually Fred bought 960 millilitres more fabric softer than bleach.

2. Fred bought 1.95 liters more laundry detergent than bleach.

Solution:

Fred bought laundry detergent = 4 liters

Fred bought bleach = 2.3 liters

Fred bought more laundry detergent than bleach = 4 - 2.3 = 1.7 liters

Hence, it is false and actually Fred bought 1.7 liters more laundry detergent than bleach.

3. Fred bought 960 millilitres more fabric softener than bleach.

It is true, as solved above:

4. Fred bought 170 millilitres more laundry detergent than bleach.

Solution:

Solved above:

Fred bought 1.7 liters more laundry detergent than bleach.

1.7 liters = 1.7 $\times$ 1000 = 1700 millilitres

1.7 liters = 1700 millilitres not 170 millilitres

Hence, it is false.

5. Fred bought 0.96 liters more fabric softener than bleach.

Solution:

Solved above:

Fred bought 960 millilitres more fabric softer than bleach.

1000 millilitres = 1 liters

1 millilitre = $\frac{1}{1000}$

960 millilitre = $\frac{1}{1000}\times960=\frac{960}{1000} =0.96\ liter$

960 millilitres = 0.96 liter

Hence, it is true.

Answer:

$\huge\boxed{\sf 16}$

Step-by-step explanation:

Given expression is:

= 10 + 3(12 ÷ (3x))

Put x = 2 nd use PEDMAS [Parenthesis Exponents Division Multiplication Addition Subtraction "in that order"]

= 10 + 3(12 ÷ (3)(2))

Solve Parenthesis

= 10 + 3(12 ÷ 6)

Now, Divide

= 10 + 3(2)

Now, Multiply

= 10 + 6

Now, Add

= 16

$\rule[225]{225}{2}$

Hope this helped!
