Answer:
1: X= 8, 2: 2/5 or 0.4
Step-by-step explanation:
1: 2(2x + 1) + x = x + 2x + 18
5x + 2 = 3x + 18
2x = 16
x = 8
2: 2x + x + 2x = 10 + x
5x = 10 + x
4x = 10
x = 4/10
x = 2/5
x = 0.4
A. False. The domain (x-coordinates) starts at 0, not at 100.
b. True. The range (y-coordinates) does start at 100 and increases.
c. True. The graph moves up to the right showing an increase in y as x increases.
d. True. Point (40, 222.11) means that when x = 40 years, y = $222.11.
e. False. The initial point is at x = 0 when the account was opened. At x = 1, it is already 1 year after the account was opened.
A great way to figure this out is to actually multiply it. 2/5 x 5/1 You can simplify numbers diagonally, so the two fives can both cancel out into ones. now we have 2/1 x 1/1, which is the same as 2x1 This equals 2, which is less than five.
One great thing to know is that anything multiplied by a number less than one (a fraction or a decimal) will always be smaller than the original number.
Answer: 2
Hope this helped!! (:
Answer:
14
Step-by-step explanation:
divide 70 into 5
if you were to draw it out it would be 5 circles and you put one line until you reach 70 in each circle you would get 14
