Answer:
30
Step-by-step explanation:
102+48=150
180-150=30
Answer:
100
Step-by-step explanation:
The solutions are (2.1925, 5.1925) and (-3.1925, -0.1925)
<em><u>Solution:</u></em>
Given that,

<em><u>We have to substitute eqn 1 in eqn 2</u></em>






Substitute x = 2.1925 in eqn 1
y = 2.1925 + 3
y = 5.1925
Substitute x = -3.1925 in eqn 1
y = -3.1925 + 3
y = -0.1925
Thus the solutions are (2.1925, 5.1925) and (-3.1925, -0.1925)
3 and 1 half is also known as 3.5,
3.5 x 3.5 = 12.25
in fractions that is 12 and 1 quarter
0.25 is rational because it is a terminating (means 'its stops') fraction.
