Answer:

The percent decrease is 14%.

Step-by-step explanation:

To answer this question you have to do percent change. To do this you have to do change/original, change divided by original. So the first thing that you have to do is subtract the smaller number from the bigger number. In the case of this problem 22,955 - 19,700. Once you do this you will get your change, 3,255. Then you want to do your change/original, 3,255/22,955 and divide. On you do this you are probably going to get a weird decimal place. In ths problem you get 0.141799172... So what you are going to do is multiply at weird decimal by 100. This will give you your percent, 14.1799172. Then you can round that to whatever you need it to be. For this problem you get 14%.

Since 111, 777, and 999 are all bigger than 20, make them smaller. Take out one 1, two 7, and two 9  (5 numbers):  11 + 7 + 9 ≠ 20 (it equals 27). Now take out number 7.  (If you take out number 1 [1+7+9=17, not 20] and of you take out number 9 [11+7=18, not 20].

11 + 9 = 20  (you took out numbers: 1, 7, 7, 7, 9 and 9 [6 numbers]).

Lily bought 22.17 pounds of grapefruit. The lightest grapefruit weighed 1.3 pounds. The heaviest grapefruit weighed 1.7 pounds.
nalin [4]

Answer:

<em>Approximately 15 grapefruits</em>

Step-by-step explanation:

<u>Average Value</u>

The mean or average of a sample is a number that represents the whole set by the center value of them. The formula to compute the average is

\displaystyle \bar x=\frac{\sum x_i}{n}

Where xi is the value of the element i and n is the number of elements in the set

We need to find an estimate of how many grapefruits Lily purchased knowing the heaviest and the lightest weight of the set. We can find the average value by using the two extreme values:

\displaystyle \bar x=\frac{1.3+1.7}{2}=1.5

If each grapefruit weighed 1.5 pounds, then we can estimate the 22.17 pounds of them will contain

22.17/1.5\approx 15\  \text{grapefruits}

Solve the following inequality: 2(x 1) – (–x 5) ≤ –18
8_murik_8 [283]
I hope this is correct



Simplifying (2x + -1)(x + -3) = 18 Reorder the terms: (-1 + 2x)(x + -3) = 18 Reorder the terms: (-1 + 2x)(-3 + x) = 18 Multiply (-1 + 2x) * (-3 + x) (-1(-3 + x) + 2x * (-3 + x)) = 18 ((-3 * -1 + x * -1) + 2x * (-3 + x)) = 18 ((3 + -1x) + 2x * (-3 + x)) = 18 (3 + -1x + (-3 * 2x + x * 2x)) = 18 (3 + -1x + (-6x + 2x2)) = 18 Combine like terms: -1x + -6x = -7x (3 + -7x + 2x2) = 18 Solving 3 + -7x + 2x2 = 18 Solving for variable 'x'. Reorder the terms: 3 + -18 + -7x + 2x2 = 18 + -18 Combine like terms: 3 + -18 = -15 -15 + -7x + 2x2 = 18 + -18 Combine like terms: 18 + -18 = 0 -15 + -7x + 2x2 = 0 Factor a trinomial. (-3 + -2x)(5 + -1x) = 0
