Tommy had 40 oranges to give to 3 groups of children. - The first group ate 30% of the total oranges.
- The second group ate 7 of the total oranges.
- The third group ate 1/8 of the total oranges.
How many oranges were left?

16

Step-by-step explanation:

1st group = 30% or .3 as a decimal

.3 * 40 = 12

2nd group = ate 7

Third group = 1/8 or .125 as a decimal

.125 * 20 = 5

12 + 7 + 5 = 24

40 -24 = 16

mental cunning

explanation:

he is often referred to as a man of twists and turns

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
