Use the equation 4.9x - 1.9 = 27.5
a. what two properties of equality do you need to use to solve the equation?

b. the solution is x=?

You would need to use addition and division to solve.

The answer would be 6.

Step-by-step explanation:

Start with the equation.

4.9x - 1.9 = 27.5

Add 1.9 to both sides of the equation.

4.9x = 29.4

Divide both side of the equation by 4.9

x = 6

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).
