When a number is increased by 9 it is five times its opposite. find the number.

Let the unknown number be .

Then the opposite of this unknown number will be .

It is given to us in the question that when this unknown number, is increased by 9, or in other words when 9 is added to this unknown number, , then this becomes 5 times it's opposite, which is .

Thus, from the given condition in the question, the equation we get is as:

We will solve this by isolating as:

Thus the required number is -1.5

probability for j is 1/4

while

a is 1/6

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
