Answer:
Number of Dolls = 28.
Number of Balls = 32.
Number of Cars = 20.
Step-by-step explanation:
Given the ratio of the number of dolls to the number of balls to the number of cars is 7 : 8 : 5.
Suppose the highest common factor of the three numbers be 'X'.
Then, Number of Dolls = 7x
Number of Balls = 8x
Number of Cars = 5x
Given the total number of dolls, balls, and cars is 80.
It means 7x + 8x + 5x = 80.
20x = 80
x = 80/20 = 4.
So, Number of Dolls = 7*4 = 28.
Number of Balls = 8*4 = 32.
Number of Cars = 5*4 = 20.
Answer:
17/24
Step-by-step explanation:
Find common denominators...
1/3 = 8/24
3/8 = 9/24
Now add...
17/24 of the cake was eaten
Hope this helps :)
Answer:
So x = 20
Step-by-step explanation:
AB + BC = AC sum of a segment is sum of its pieces
AB + AB = AC B is the midpoint, so AB = BC
2x + 2x = 3x + 20 putting in for AB (twice!) and AC
4x = 3x + 20 collect like terms
x = 20 subtract 3x on both sides.
