Y=|x−3|+|x+2|−|x−5|, if 3

denis-greek [22]

Answer:

Step-by-step explanation:

I take it you want x = 3

y = abs(3 - 3) + abs(3 + 2) - abs(3 - 5)

y = 0 + 5 - abs(-2)

y = 0 + 5 - (2)

y = 0 + 5 - 2

y = 3

If you meant something else please leave a note.

Now all you do is redo the problem for 5

y = abs(5 - 3) + abs(5 + 2) - abs(5 - 5)

y = abs(2) + abs(7) - abs(0)

y = 2 + 7 - 0

y = 9

Now set up your inequality

3 < y < 9

The number of measles cases increased 13.6 % to 57 cases this year, what was the number of cases prior to the increase? (Express

ELEN [110]

Answer:

The number of cases prior to the increase is 50.

Step-by-step explanation:

It is given that the number of measles cases increased by 13.6% and the number of cases after increase is 57.

We need to find the number of cases prior to the increase.

Let x be the number of cases prior to the increase.

x + 13.6% of x = 57

$x+x\times \frac{13.6}{100}=57$

$x+0.136x=57$

$1.136x=57$

Divide both the sides by 1.136.

$\frac{1.136x}{1.136}=\frac{57}{1.136}$

$x=50.176$

$x\approx 50$

Therefore the number of cases prior to the increase is 50.

London found an equivalent ratio to the ratio shown below by multiplying both side of 7. What is the equivalent ratio London fou

Xelga [282]

Answer:

<em>It can also be expressed as 35/14.</em>

Step-by-step explanation:

<u>Equivalent Ratio</u>

A ratio is a relation between two numbers a, b in the format a:b and it's equivalent to the division a/b.

Since it's equivalent to a division or a fraction, it can be simplified or amplified by multiplying or dividing both sides by the same number.

The ratio 5:2 can be amplified by multiplied by 7 as follows:

5*7:2*7 = 35:14.

It can also be expressed as 35/14.

What two rational numbers are less than 1.6 but greater than -1.6

Harlamova29_29 [7]

let's firstly convert the decimal to a fraction, namely a rational.

so we have one decimal, thus let's use 1 zero at the denominator and lose the dot on the numerator.

$\bf 1.\underline{6}\implies \cfrac{16}{1\underline{0}}\implies \stackrel{simplified}{\cfrac{8}{5}}$

so then, what rationals are between -8/5 and +8/5? well, a huge amount hmmm let's pick two.

$\bf \boxed{-\cfrac{8}{5}}\rule[0.35em]{9.5em}{0.25pt}~~-\cfrac{3}{5}~~\rule[0.35em]{2em}{0.25pt}0\rule[0.35em]{10em}{0.25pt}~~\cfrac{6}{5}~~\rule[0.35em]{2.5em}{0.25pt}\boxed{\cfrac{8}{5}}$
