Answer:
Number of marbles with Williams at the starting = 192
Step-by-step explanation:
Let total number of marbles with Williams = m
He lost marbles = 25% of the total number
=
=
Remaining marbles with Williams = m -
=
He gave marbles to his brother = th of the remaining marbles
=
=
Remaining marbles after giving marbles to his brother = 120
Therefore,
m =
m = 192
Number of marbles with Williams at the starting = 192
Answer:

Answer:
similar triangles
Step-by-step explanation:
First of all, what are similar shapes? Well, two shapes are similar if you can turn one into the other by moving, rotating, flipping, or scaling. That means you can make one shape bigger or smaller. In this case, we know that triangles ABC and DEF are mathematically similar. The area of triangles ABC is , so we need to know the area of triangle DEF.
From math, let's call the scaling factor, so we know that for any similar figures, the ratio of the areas of any are in proportion to . In other words, if is the area of triangle ABC, and is the area of triangle DEF, then we can write the following relationship:
50% off means half price, so half of 49.98 is 24.99
the necklace now costs 24.99 dollars
63/240 seats or 21/80
The greatest common denominator is 3, so you would divide both by 3.
