Answer:

In this problem you have to get rid of the 13 so you take the opposite of the number which is -13 and subtract it by 13 and when you do this you have to do the same thing on the other side so you would do 48-13 and that would give you get 35 so -5x=35. This is not the same because on B it says positive 5x, and on A it is negative 5x.

Need help asap 10 points, provide explanation please.
hram777 [196]

Answer:

Step-by-step explanation:

Use the distance formula between points to find all sides:

d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}

AB=\sqrt{13}

BC=\sqrt{13}

CA=\sqrt{26}

This is a 45° 45° 90° triangle, where two of the sides are equal and the other side is the first two sides times \sqrt{2}, so yes, it is a right triangle.

If a child accidentally swallowed 1.6 fluidounces of FEOSOL Elixir, containing 2/3 gr of ferrous sulfate per 5 mL, how many mill
GuDViN [60]

Answer:

the amount of ferrous sulphate child will digest = 213.3 mg

Step-by-step explanation:

Given,

Amount of FEOSOL Elixir swallowed by child = 1.6 Fluid ounces

                                                                           = 1.6 x 29.57 ml

                                                                           = 47.312 ml

\textrm{Amount of ferrous sulphate contained in 5 ml of of solution}=\ \dfrac{2}{3}\ grams

\textrm{So, amount of ferrous sulphate contained in 1 ml of solution}\ =\ \dfrac{2}{3\times 5}

                                                                    =\ \dfrac{2}{15}

\textrm{So,the amount of ferrous sulphate contained in the 1.6 ml of FEROSOL}=1.6\times \dfrac{2}{15}

                  =\ \dfrac{3.2}{15}

                  = 0.2133 gram

                  = 213.3 mg

So, the amount of ferrous sulphate child will digest = 213.3 mg

2x-3y=5.5<br> What is the solution to the system of equations shown above
sasho [114]

Answer:

⸻⸻⸻⸻⸻

Solving

2X + 3Y = 5.5

⸻⸻⸻⸻⸻

Simplifying

2X + 3Y = 5.5

⸻⸻⸻⸻⸻

<u>Solving for variable 'X'. </u>

<u> Move all terms containing X to the left, all other terms to the right.</u>

⸻⸻⸻⸻⸻

Add -3y to each side of the equation.

2x + 3y + -3y = 5.5 + -3y

⸻⸻⸻⸻⸻

Combine terms: 3y + -3y = 0.

2x + 0 = 5.5 + -3y

2x = 5.5 + -3y

⸻⸻⸻⸻⸻

Divide each side by 2.

x = 2.75 + -1.5y

⸻⸻⸻⸻⸻

Simplifying.

x = 2.75 + -1.5y

⸻⸻⸻⸻⸻
