It Percent Change pls hurry 30 to 55 (round to the nearest hundredth)

Harlamova29_29 [7]

Answer:

83.33% change

Check work:

30 x 0.8333 = 24.999

30 + 24.999 = 54.999 or about 55

What’s different about solving inequalities when you have to multiply or divide by a negative number? Can you explain why a spec

Sergeu [11.5K]

Alright, let's take an example. 1 is less than 2, so we can write it as 1<2. However, if we multiplied both sides by -1 without changing anything else, we get -1<-2, but -1 is greater than -2 because it is less negative, so the correct way of writing it would be -1>-2. Therefore, since a number that is less positive than another becomes less negative (and therefore higher) when both are multiplied by -1, we have to change the side of the inequality

Answer:

1/3, 0.5, 4/6, 4/5

Step-by-step explanation:

For the same numerator, the fraction with the larger denominator is the smaller fraction.

0.5 = 1/2

So, we have two fractions with numerators of 1, and two fractions with numerators of 4. The smaller fraction with a numerator of 4 has a numerator that is more than half the denominator, so its value is more than 1/2.

The least-to-greatest order is ...

1/3, 1/2, 4/6, 4/5

In the original number format, this is ...

1/3, 0.5, 4/6, 4/5

(2x+1)/2=(x+2)/5 if possible can you show me step by step how to get the answer

katrin2010 [14]

Answer:

$\boxed{\bold{Decimal \ Form: \ x \ = \ -0.125}}$

$\boxed{\bold{Fraction \ Form:x=-\frac{1}{8}}}$

Step By Step Explanation:

Apply Fraction Cross Multiply: If $\bold{\frac{a}{b}=\frac{c}{d}:then\ a\cdot \:d=b\cdot \:c}$

$\bold{\left(2x+1\right)\cdot \:5=2\left(x+2\right)}$

$\bold{\left(2x+1\right)\cdot \:5: \ 10x+5}$

$\bold{2\left(x+2\right): \ 2x+4}$

$\bold{10x+5=2x+4}$

Subtract 4 From Both Sides

$\bold{10x+5-5=2x+4-5}$

Simplify

$\bold{10x=2x-1}$

Subtract 2x From Both Sides

$\bold{10x-2x=2x-1-2x}$

Simplify

$\bold{8x=-1}$

Divide Both Sides By 8

$\bold{\frac{8x}{8}=\frac{-1}{8}}$

Simplify

$\bold{x=-\frac{1}{8}}$

Turn Fraction Into Decimal

$\bold{-1 \ \div \ 8 \ = \ -0.125}$

$\bold{-0.125}$

Use grid paper to find the median of the data. 9,7,2,4,3,5,9,6,8,0,3,8 The median is....

ololo11 [35]

You want to put the numbers in order from least to greatest like this-
0,2,3,3,4,5,6,7,8,8,9,9
then you want to start from the left end and the right end then you start crossing them off until you have a median, you keep crossing off until you get 5 and 6 in the middle, now you have to find the mean of the two numbers you add them together than you divide by 2 like this- 5+6=11 11/2=5.5
5.5 is your answer
