Answer:
<em>The values are a=6, b=8</em>
Step-by-step explanation:
The following system of equations
ax - by = 4
bx - ay = 10
Has the solution x=2, y=1. Substituting:
2a - b = 4 [1]
2b - a = 10 [2]
Multiply [1] by 2:
4a - 2b = 8
Add with [2]:
3a = 18
a = 18/3 = 6
a = 6
From [1]:
2*6 - b = 4
b = 12 - 4
b = 8
The values are a=6, b=8

Answer:
<em>The quotient will be between 18 and 19.</em>
<em>Estimated quotient will be 18.75</em>
Step-by-step explanation:
The closest number to 75 which is divisible by 4 and <u>less than 75</u> is : 72 and
the closest number to 75 which is divisible by 4 and <u>greater than 75</u> is : 76
Now,
and 
That means, the quotient for
will be between 18 and 19.
As, 75 is 1 less than 76, so the quotient will be
or
less than 19.
So, the quotient will be:
