Tia takes $50 from her bank account to pay for bus fare for the month. She does this each month for 7 months in a row. Which equation models this situation and represents the change it causes in Tia's bank balance?
(-$50) + 7 =543
(-550) * 7 =-$350
А
B
С
$50 (-7) = $350
D
(-850) - 7 =-557

Step-by-step explanation:

Taking $50 each month causes  - $50 change to bank balance

Repeating same for 7 month:

Correct option is B

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).
