2x + y = 5 x + y = 4 a. x = 1, y = 3 b. x = 1, y = 5 c. x = 3, y = 1 d. x = 9, y = -5

we are given with the system of equations

Now we can solve these equations together using substitution method

Now substitute x=1 in in the second equation we get

3201

step-by-step explanation:

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
