Answer:
500 figures.
Step-by-step explanation:
We know that 185 figures is 37% of her entire collection.
Let c represent the total amount of figures.
Since 185 is 37% or 0.37 <em>of</em> her total collection, we can write the equation:

Remember that the keyword <em>of</em> tells us it's multiplication.
Therefore, to find the number of figures in her total collection, divide both sides by 0.37:

Evaluate. Use a calculator. So:

Sofia's total collection has 500 figures.
18. 12/4 =3, 36/12 =3 the ratio is 3
19. 108/162 =0.667, 72/108= 0.667 the ratio is 0.667 or 2/3
20. 2/3 / 4/3 = 1/2, 1/3 /2/3 = 1/2, the ratio is 1/2
This is true because a shape with 4 sides are true
Answer: 2b-21a
Step-by-step explanation:
1. 3x+1=4/5(4x)
