Answer:
40 girls
Step-by-step explanation:
if you multiply 5 times 10, then you have to multiply the other side by 10 too. So 5 times 10 equals 50, and 4 times 10 equals 40.
40+50+=90.
Sorry just commenting for something
I'm here buddy,
so, let's take the value of the two bags with equal weight as x.
= x + x + (x + ) =
= 3x + =
= 3x = -
( let's take the LCM of 4 and 5 = 20
= 3x = -
= 3x =
= x = ÷ = × =
So, the weight of the equal bags are and the weight of the third bag ( heavy one ) is + = + =
1st bag = kg
2nd bag = kg
3rd bag = kg
Hope it helps...
