Answer:
39 and 65
Step-by-step explanation:
the ratio of the two numbers is 3 : 5
sum the parts of the ratio, 3 + 5 = 8 parts
divide the sum by 8 to find the value of one part of the ratio
104 ÷ 8 = 13 ← value of 1 part of the ratio , then
3 parts = 3 × 13 = 39
5 parts = 5 × 13 = 65
the two numbers are 39 and 65

Answer:
+2Na
Step-by-step explanation:
its like algebra kinda when you have a 3y or 2x your Na ion is multiplied by 2 becoming 2Na
4,000,000 and 20,000,000 miles²
let x be the area of one desert then 5x is the area of the other
sum = x + 5x = 24,000,000
6x = 24,000,000
divide both sides by 6
x = 4,000,000
one desert is 4,000,000 miles²
and the other is (5 × 4,000,000)= 20,000,000 miles²
