5t/3-2/3*(t+4)=1
5t/3-2t/3+8/3=1
3t/3+8/3=1
8/3-1=t
8/3-3/3=t
5/3=t
The answer is 4 2/3 minus 2
Answer:
70 , 84 , 105
Step-by-step explanation:
sum their ages , 10 + 12 + 15 = 37
divide the amount by this sum to find the value of one part of the ratio.
259 ÷ 37 = 7 ← value of 1 part of the ratio , then
10 parts = 10 × 7 = 70 euros ← Tom's share
12 parts = 12 × 7 = 84 euros ← Mary's share
15 parts = 15 × 7 = 105 euros ← Bill's share
There are 1000 Times more people on earth right now than there was in 4,000 BCE. It's just 7billion divided by 7million.
