Mathematics
1 answer:
m_a_m_a [10]3 years ago
3 0

Answer:

t=10

Step-by-step explanation:

4=t/2.5

4=t/25/10

divide 25and10 by 5=5/2

4=t/5/2

4=t×2/5

multiply both sides of the equation by 5

5×4=t×2/5×5

20=t×10/5

20=t×2

Help pls reallyyyyyyyyyyyyyyyyyy
Ivan

Answer:

10

Step-by-step explanation:

j=6

k=4

Rewrite the equation. So let's do that-

2.5(6*4)/6

6 and the other 6 cancel out so we are left with 2.5*4

Which is then equal to 10.

By the way, whenever you see the same number in a division problem on the numerator and denominator, just cancel them out because if you still did 2.5(6*4)/6, you would still get 10. I was just simplifying it!

ms. jeffers is splitting $775 among her three sons. of the oldest gets twice as much as the youngest and the middle son gets $35
Angelina_Jolie [31]

The oldest son will get $370, the middle will get $220 and the youngest will get $185.

Step-by-step explanation:

Given,

Total amount to be split = $775

Let,

Oldest son's share = x

Middle son's share = y

Youngest son's share = z

According to given statement;

x+y+z=775     Eqn 1

the oldest gets twice as much as the youngest

x = 2z             Eqn 2

the middle son gets $35 more than the youngest

y = z+35         Eqn 3

Putting value of x and y from Eqn 2 and 3 in Eqn 1

2z+(z+35)+z=775\\2z+z+35+z=775\\4z=775-35\\4z=740\\

Dividing both sides by 4

\frac{4z}{4}=\frac{740}{4}\\z=185

Putting z=185 in Eqn 2

x=2(185)\\x=370

Putting z=185 in Eqn 3

y=185+35\\y=220

The oldest son will get $370, the middle will get $220 and the youngest will get $185.
