Answer:
Given that,
R = 3x + 9y
Also, given that,
y = 6
R = 7
We have to find the value of x
For that, you can to put 6 and 7 to the equation instead of y and R respectively.
R = 3x + 9y
7 = 3x + 9 × 6
7 = 3x + 54
7 - 54 = 3x
- 47 = 3x

Given 2 sides and 1 included angle, the area of a triangle can be solved using the formula:
Area = ab (sin C)/2
Substituting the given values:
Area = 10 * 23 * (sin 95)/2
Area = 114.56 sq. units
1.5 tsp x 800 cakes = 1200 tsp.
1 tsp = 5 ml
1200 x 5 = 6000 ml
1 ml = 0.001 liter
6000 x 0.001 = 6 liters
