Suppose y varies inversely with x, and y = 25 when x = 1/5. What is the value of y when x = 5 ?

y = 1

Step-by-step explanation:

Given that y varies inversely with x then the equation relating them is

y = ← k is the constant of variation

To find k use the condition y = 25 when x = , then

25 = = 5k ( divide both sides by 5 )

5 = k

y = ← equation of variation

When x = 5, then

y = = 1

c. 65°

step-by-step explanation:

we are given a triangle with two known angles, 62° and 53°, while the third angle x is unknown and we are to find its value.

we know that the sum of angles in a triangle is equal to a total of 180 degrees. so we can write it as:

x + 62° + 53° = 180°

solving to find the value of x:

x = 180 - (62 + 53) = 65°

therefore, the value of x in this triangle is 65°.

the answer is c. hope this !
