Natasha_Volkova [10]
Let x be the number of 5 points question.
Let y be the number of 2 points question.

Total number of questions is 38
x + y = 38 

Total points is 100
5x + 2y = 100

x + y = 38 ------------- (1)
5x + 2y = 100 ---------(2)

From (1):
x + y = 38
x = 38 - y -------------- sub into (2)
5(38 - y) + 2y = 100
190 - 5y + 2y = 100
3y = 90
y = 30 ------------------ sub into (1)
x + 30 = 38
x = 38 - 30
x = 8

There are 8 5-point questions and 30 2-point questions

Leah has meters of cloth, which she divides equally among her friends. Each friend gets meters of cloth.
Brrunno [24]

Answer: 6

Step-by-step explanation:

Here's the complete question:

Leah has 8 4/7 meters of cloth, which she divides equally among her friends. Each friend 10/7 gets meters of cloth. She distributed the cloth to ---- friends.

Total length of the cloth = 8 4/7m

Number of friends = Unknown

Amount of length gotten by each friend= 10/7

The number of friends that she shred the cloth among will be:

= Total length of cloth / Length gotten by each friend

= 8 4/7 ÷ 10/7

= 60/7 ÷ 10/7

= 6/7 × 7/10.

= 60/10

= 6.

It was shared among 6 friends
