Answer:

x=-9, y=-6. (-9, -6).

Step-by-step explanation:

4x-5y=-6

-6x+7y=12

----------------

6(4x-5y)=6(-6)

4(-6x+7y)=4(12)

-----------------------

24x-30y=-36

-24x+28y=48

-----------------------

-2y=12

y=12/-2

y=-6

4x-5(-6)=-6

4x+30=-6

4x=-6-30

4x=-36

x=-36/4

x=-9

Order from least to greatest. 10/8, 1.2, 0.556, 0.8%
Vsevolod [243]

The order from least to greatest is 0<u>.8%, 0.556, 1.2 and 10/8</u>

<h3>Ordering of numbers</h3>

In order to order the given numbers, we will first have to write them as a percentage as shown.

Given the number below

10/8, 1.2, 0.556, 0.8%

Convert to percentage

10/8 = 125%

1.2 = 120%

0.556 = 55.6%

0.8%

Hence the order from least to greatest is 0<u>.8%, 0.556, 1.2 and 10/8</u>

A cat requires a 3 mL injection of a 0.5% solution. How many milligrams will it receive per injection?
Kay [80]
<h2>Hello!</h2>

The answer is: 15mg

<h2>Why?</h2>

0.5% means that there are 0.5 grams per 100 mL,  and a 0.5 grams are equal to 500 milligrams.

So, to calculate how many milligrams will be received per injection, we need to make the following calculations:

3mL*\frac{500mg}{100mL}=15mg

Have a nice day!
