If an average orange weighs 75 g, how many oranges would weigh 4.5 kg?​
sashaice [31]

Answer: 60 oranges

Step-by-step explanation:

<u>Given information</u>

Weight = 75 g / orange

Total = 4.5 kg

<u>Given formula</u>

Total = Number of oranges × Average weight

<u>Convert Kilogram unit to Gram</u>

1 kg = 1000 g

4.5 kg = 4.5 × 1000 = 4500 g

<u>Substitute values into the given formula</u>

Total = Number of oranges × Average weight

Number of oranges = Total / Average weight

Number of oranges = 4500 / 75

<u>Simplify by division</u>

\Large\boxed{Number~of~oranges~=~60}

Hope this helps!! :)

The larger of two numbers is 10 less than twice the smaller number. If the sum of the two
natka813 [3]

Answer:

Let the larger number = y and the smaller number = x.

The largest number is 10 less than twice the smaller number. Remember that less than means subtract the 10 from the other amount while twice means multiply by two. Therefore,

y = 2x - 10

The sum of the two numbers is 38. Remember sum means add the two numbers to get their result. Therefore,

x + y = 38

Since y = 2x - 10, we rewrite the lower equation as:

x + (2x - 10) = 38

Solving:

3x - 10 = 38

3x = 48

x = 16

The lesser number is 16 and the greater number is 2(16) - 10 or 22.
