Percent increase and decrease. Original number:45 New number: 18

Mathematics
1 answer:
andre [41]3 years ago
4 0

Answer:

60% decrease

Step-by-step explanation:

To find the percentage increase/ decrease construct a fraction with numerator showing increase/ decrease and denominator with original number then multiply the fraction by 100%

here the decrease = 45 - 18 = 27

percent decrease = \frac{decrease}{original} × 100%

                             = \frac{27}{45} × 100% = 60%

The graph shows the solution to which system of equations?
Sedaia [141]
So let's start by guesstimating the slopes:
the green line has a slope close to -x, but more negative than that, possibly -2; the pink line has a slope close to +x, but higher towards +2.

Next let's look at the solution: the two lines intersect at the point (1, -1).
**you could just simple plug that x (1) into all the equations, but let's rule out answers anyway. ;)

A) is incorrect because the slopes of -1 and +1 are off from out predicted -2 and +2
B) is incorrect because of a similar reason, the slopes of +3 and +1 don't make any sense
C) Ooh, we do have a +2 and -2 for the slopes, and... violà! plug in 1 for the x's and we get -1 for the y in both equations
D) slopes are closer than in A and B, but plugging in 1 doesn't get us -1

So the correct answer is:
C) y = 2x - 3 and y = −2x + 1

Neporo4naja [7]
61 = 3b + 7

3b + 7 = 61

3b = 61 - 7

3b = 54

b = 54/3

b = 18.
