Answer: The correct options are,

x+y < 30

y ≥ 12

Step-by-step explanation:

Here, x represent the number of small cones and y represent the number of large cones.

∵ Large cones are at least 12,

⇒ y ≥ 12,

Now, total cones = x + y

∵ There are fewer than 30 cones,

I.e.  x + y < 30,

Now, number of cones can not be negative,

⇒ x, y ≥ 0

Since they are FEWER than 30 total cones, the sum of x small cones and y large one must be LESS THAN 30: x+y <30
He needs AT LEAST a dozen (12), so that means that 12 will work or more than 12:
y \geqslant 12

4[( 8 + 4)10] + 24 devided by 2^3
Nikolay [14]
4[(8+4)10] + 24
so 8 + 4 is 12. Multiply that by 10 and that's 120.
120 + 24 is 144
144 × 4 is 576
for "devided by 2^3" do you mean divided by 2/3?
If so then its 576 ÷ 2/3 = 96
