Answer:
100 cm
Step-by-step explanation:
This is a linear function with an equation of y = 20x.
Plug 5 in for x to get 100 as your answer.
At the bank, Derek made 7 withdrawals, each in the same amount. His brother, John, made 5 withdrawls, each in the same amount.
Let x be the amount of one of Derek's withdrawals
Each of John's withdrawals was $5 more than each withdrawal that Derek made.
x + 5 is t the amount of one of John's withdrawals
Derek made 7 withdrawals
So amount withdraw 7 times = 7x
John made 5 withdrawals
So amount withdraw 5 times = 5(x+5)
Both Derek and John withdrew the same amount of money in the end
(A)7x = 5(x+5)
(B) Solve for x
7x = 5x + 25
Subtract 5x from both sides
2x = 25
Divide by 2
x = 12.5
(C) check your solution
we plug in 12.5 for x in 7x= 5x + 25
7(12.5) = 5(12.5) + 25
87.5 = 62.5+ 25
87.5 = 87.5
(D) Each brother withdrawal 87.5 dollars
Answer:
find 80 percent
Step-by-step explanation:
Answer:
c. No, for each height, there are people of different ages.
Step-by-step explanation:
We say that y is a function of x when there is a relationship between x and y. For example, the distance you run on a single day and your average speed.
However
There is no relationship between age and height. For example, we may both be the same age and have very different heights.
So the correct answer is:
c. No, for each height, there are people of different ages.
