A construction worker bought several bottles of juice for $3 at the convenience store. She paid for them with a $20 bill.If "J" represents the number of bottles of juice,write an expression for the change she should receive. Solve.Show each step.

Answers

Answer 1

Answer: Each bottle of juice costs $3, so to find the total price of the bottles, you would have to multiply the number of bottles by $3, or:
3×J

Since she paid for them with a $20 bill, you need to subtract the total price of the bottles (shown above) from 20. Let's say "y" is the amount of change she receives:
y=20-(3×J)

True or false:x/3 is equivalent to 1/3x.explain your reasoning.

Answers

Yes, both the expressions are equivalent.

What is an expression?

An expression in maths is a sentence with a minimum of two numbers or variables and at least one maths operation. This maths operation can be addition, subtraction, multiplication, or division.

Given that, x/3 is equivalent to 1/3x, yes or not?

So, we can write x/3 as

1/3×x

= x/3

Since, either you multiply by 1/3 or divide by 3 both are same thing,

1/3×x = x/3 = 0.333x

for example; 4÷2 = 2 or 4×1/2 = 2, in both case the answer is same, that means the expression given are also equal.

Hence, we can conclude both the expressions are equivalent.

Lizzy bought 4 bags of apples at the store. Her mom gave her 8 more apples. Now Lizzy has 36 apples. How many apples were in each bag?

Answers

36 - 8 = 28
Lizzy bought a total of 18 apples from the store.
28/4=7
There are 7 apples in each bag.

4b+8=36
Subtract 8 from both sides
4b=28
Divide by 4 on both sides to get b by itself
b=7

7 apples were in each bag
