What times 3 equals 4.5 ( in fraction form)
j/3 = 4.5 solve for j

a) 1.5

b) j = 13.5

Explanation:

a) Let the unknown number be x

To calculate the value that we will multiply by 3 to give 4.5, we can express this mathematically as;

x × 3 = 4.5 where x is unknown

Dividing both sides by 3;

x = 4.5/3

x = 1.5

The value that we will multiply with 3 to give 5 is 1.5.

b) Given the equation j/3 = 4.5,

To solve for j, we will cross multiply the equation to have;

j = 3×4.5

j = 13.5

step-by-step explanation:

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).
