<span>4x – 5y = –18 (1st)
3x + 2y = –2 (2nd)
Multiply 1st equation by 2 and 2nd equation by 5
</span>4x – 5y = –18 (1st) (mul. 2)
3x + 2y = –2 (2nd) (mul. 5)
8x - 10y = - 36
15x + 10y = - 10
-----------------------add
23x = - 46
x = -2
3x + 2y = –2
3(-2) + 2y = –2
-6 + 2y = -2
2y = 4
y = 2

Answer:
The diameter of the circle is 40 units
Step-by-step explanation:
Linear means in a straight line, non linear n o line
39.99 + 0.13m < = 44
0.13m < = 44 - 39.99
0.13m < = 4.01
m < = 4.01 / 0.13
m < = 30.84......so the most that he can send or receive is 30
