Step-by-step explanation:
copy and paste the link on to your search bar
A : B : C = 5 : 8 : 10
A+ B = 5x + 8x = 13x
13x - 10x = 60
3x = 60
x = 20
Total = 5x + 8x + 10x = 23x
23x = 23(20) = 460 <========= answer
Answer:
11/29/2020
Step-by-step explanation:
Every seventh and fifth day, both numbers are prime, 5 x 7 = 35, so 35 days after October 24th is November 29th because October has 30 days.
Answer:
x = 15/7
Step-by-step explanation:
Cross multiply.
2(5+x) = 5(5-x)
Expand the brackets.
10+2x = 25 - 5x
Add 5x and -10 on both sides.
2x + 5x = 25 -10
Combine like terms.
7x = 15
Divide both sides by 7.
x = 15/7
