Step-by-step explanation:
The value of x is 7......
Using the graph that is included, look at the points given. For example (30, 3). There would be 30 vegetarian dishes and 3 steak dinners for a total of 33 meals. If that is plugged into the cost equation 20(30)+3(30) it would equal $690. The next point (33, 1) would cost 20(33) + 30(1) = $690 and but gives 34 meals. However, 34 vegetarian meals would only cost 20(34)=$680 and have 34 meals.
If both types of meals need to be purchased, 33 vegetarians and 1 steak. If only vegetarians are purchased, the cost is cheaper by $10.
Answer:
736 Newtons
Step-by-step explanation:
Given
Pressure = 
Multiply both sides by Area
Area × Pressure = Force
Area = 2.3 × 1.6 = 3.68 m², hence
Force = 3.68 × 200 = 736 Newtons
Answer:
x° = 40°
Step-by-step explanation:
142° = 3x° + 22° (Vertically opposite angles)
3x° = 120°
x° = 40°
To divide complex numbers, you multiply by the conjugate. The conjugate is when you change the sign between the two terms in the denominator. Therefore, the conjugate in this one is (3+i)
