The value of______ divided by 40.01 is close to 1
guapka [62]

The value of 39.6099 divided by 40.01 is close to 1.

Solution:

Given data:

The value of______ divided by 40.01 is close to 1.

close to 1 means not exactly one which is 0.99.

Let the unknown be taken as x.

x ÷ 40.01 = close to 1

x ÷ 40.01 = 0.9999

$\frac{x}{40.01} =0.99

Do cross multiplication, we get

x =0.99\times40.01

x = 39.6099

Hence the value of 39.6099 divided by 40.01 is close to 1.

Salim and Asma are going to a fair to enjoy themselves. Their parents give Rs 49 and Rs 45 respectively as spending money. At th
Galina-37 [17]

First, let's make a variable to represent the total amount of money each spent.

How about 'r'?

Since they both spent the same amount of money, you can represent the money they have left with these two equations:

49 - r

45 - r

Because one has 3 times more than the other, it can be represented like this:

49 - r = 3(45 - r)

49 - r = 135 - 3r

Subtract 49 from both sides:

-r = 86 - 3r

Add 3r to both sides:

2r = 86

r = 43

They've both spent Rs 43

Good luck!
