Answer : The equation could you use to find p is, 
Step-by-step explanation :
Let the cost of 1 pen be, 'x'
and the cost of 1 pencil is, 'p'
As we are given that total cost of 1 pen and 1 pencil is $2.10. The equation will be:
............(1)
And we have also given that the pen costs twice as much as a pencil. The equation will be:
............(2)
Now put the equation 2 in equation 1, we get:


Thus, the equation could you use to find p is,

First mutiply your object of the question which is 9 times 16 then make sure you have the right answer then divide it by 8 and 144 the answer you got, and you get 18
Answer:
B
Step-by-step explanation:
The angle that has tan 5 / 12 is ∠ABC so A is not the answer. The angle that has cos 5 / 13 is ∠BAC so B is the answer.
Answer:
203 sq ft
Step-by-step explanation:
if you draw an imaginary line horizontally at the 11 feet mark you have a triangle sitting on top of a rectangle
Area (triangle) = 1/2 x base x height
A = 1/2 x 14 x 7
A = 7 x 7
A = 49
Area (rectangle) = length x width
A = 11 x 14
A = 154
Total Area = 49 + 154
203 sq ft
