Answer:
x = 109
Step-by-step explanation:

Answer: the answer is 3
Step-by-step explanation: The gradient (or slope) of the tangent to a curve at any particular point is given by the derivative at that point If y = x 3 then d y d x = 3 x 2 When x = 1 ⇒ d y d x = 3 So the slope equals 3
Answer:
In what problem?
Step-by-step explanation:
Answer:
m - 9 = 3/5 m (Steve has some money. After spending $9, he now has 3/5 of his original amount)
So it's just the matter of isolating m. Subtract m from both sides:
-9 = -2/5 m
Now you just need to multiply both sides by -5/2 to get your final answer.
Step-by-step explanation:
GIVEN
1) Females outnumber males by 3 to 2.
2) There are 1770 people in the city.
SOLUTION
Let the number of males be x and the number of females y. Therefore, the total number of people can be written to be:

If there are 3 females for every 2 males, we have that:

We can substitute equation (2) into equation (1) and solve for y:

Dividing both sides by 5, we have

There are 1062 females in the county.
