Step-by-step explanation:
1134 ÷ 63 = 18
Answer:
Hanna said is correct because the money is divided in the ratio 2:3
Answer:
11.5
Step-by-step explanation:
midrange formula= (high + low)/2
(18 + 5)/2
=23/2
=11.5
You would wana use SA=2lw+2lh+2hw
so SA=2(8×2)+2(8×12)+2(2×12)
make the calculations than mention how you find the surface of one side of the box than the whole surface area by using that formula
Let's solve this problem step-by-step.
STEP-BY-STEP SOLUTION:
We will be using simultaneous equations to solve this problem.
Let's establish the two equations we will be using to solve the problem.
Let Andrew's current age = a
Let Andrew's son's current age = s
Equation No. 1 -
a = 3s
Equation No. 2 -
a - 10 = 5s
To begin with, we will substitute the value of ( a ) from the first equation into the second equation to solve for ( s ).
Equation No. 2 -
a - 10 = 5s
( 3s ) - 10 = 5s
3s - 5s = 10
- 2s = 10
s = 10 / - 2
s = - 5
Next we will substitute the value of ( s ) from the second equation into the first equation to solve for ( a ).
Equation No. 1 -
a = 3s
a = 3 ( - 5 )
a = - 15
FINAL ANSWER:
Therefore, the present age of Andrew is - 15 and the present age of Andrew's son's is - 5.
It isn't possible for someone to be negative years old, but this is the answer that I ibtained from the equations.
Hope this helps! :)
Have a lovely day! <3
