BONUS: Solve this problem by using the Guess And Check strategy. I'm thinking of a number. If you multiply it by 4, then subtract 10, and finally add 15,
you get 53. What number am I thinking of?

the answer for your question is 48

12

Step-by-step explanation:

Let number you are thinking be x

According to problem;

4x-10+15=53

4x+5=53

4x=48

×=12

b

step-by-step explanation:

u take $75 minus $60.the anwer/original($75)multiply by 100

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
