Answer:
3. Option No. 2:
6x + 2y = 22
3x + 3y = 18
4. Option No. 2:
$2.50
Step by step explanation:
4. 6x + 2y = 22
(3x + 3y = 18) * 2
- Negate
6x + 2y = 22
6x + 6y = 36
2y - 6y = 22 - 36
-4y = -14
y = -14/-4
y = 3.5
An order of onion rings = $3.50
- Substitute to find for x
6x + 2(3.5) = 22
6x + 7 = 22
6x = 22 - 7
6x = 15
x = 15/6
x = 2.5

Answer:
29
Step-by-step explanation:
Given the function f(x) = x/10x-3, if x = 0.30103;
substituting the value of x into the function;
f(0.30103) = 0.30103/10(0.30103) - 3
f(0.30103) = 0.30103/(3.0103 - 3)
f(0.30103) = 0.30103/0.0103
f(0.30103) = 29.226
f(0.30103) = 29 (to nearest whole number).
