Answer:
Step-by-step explanation:
add it all up u get -18. then divide it by 4 which is 4.5
4x - 3y = 17.....multiply by 4
5x + 4y = 60 ...multiply by 3
-----------------
16x - 12y = 68 (result of multiplying by 4
15x + 12y = 180 (result of multiplying by 3
-----------------add
31x = 248
x = 248/31
x = 8
4x - 3y = 17
4(8) - 3y = 17
32 - 3y = 17
-3y = 17 - 32
-3y = - 15
y = -15/-3
y = 5
solution is (8,5) <==
The answer was is 11 + 21*5
Lateral Surface Area of a cone = πrl
Lateral Surface Area of the ice-cream cone = π x 1 x 5.1
Lateral Surface Area of the ice-cream cone = 16 in² (nearest inch)
--------------------------------------------------------------------------
Answer: 16 in² of waffle is needed to make each cone.

Divide each by 5 , now it is 7 over 9
