Answer:
Step-by-step explanation:its yo mom
It passes it 12 times bc it only passes it 1 time each hour
Let’s define our variables:
D = dad’s age now
S = son’s age now
Given:
D=4S now
D+4=3(S+4) in 4 years
We can expand the second equation:
D+4=3S+12
D=3S+8
And we can subtract it from D=4S
D=4S-(D=3S+8)
0=S-8
S=8 the son’s age now.
D=4S=4(8)=32 the father’s age now
Check:
32+4=3(8+4)
36=3(12)
36=36 Check
I hope this helps you
Now we have to,
→ prove that 100 - [5 × (3 + 4)] = 65.
Let's solve the problem,
→ 100 - [5 × (3 + 4)] = 65
→ 100 - [5 × 7] = 65
→ 100 - 35 = 65
→ 65 = 65
→ LHS = RHS
Hence, proved the equation.
Answer:
His position is now on -18 below sea level
Step-by-step explanation:
So since Tomas is 15 feet below sea level, that means that it's -15. He rose 9 feet which now he is -6 feet below sea level. Now he descends 12 feet which means he goes back down and now he is at -18 below sea level.
