A shade of green paint is made by mixing blue paint and yellow paint in the ratio of 4 to 3. How many pints of blue paint and ye

nexus9112 [7]

Answer:

$Blue = 12$

$Yellow = 9$

Step-by-step explanation:

Given

$Blue : Yellow = 4 : 3$

Required

Determine the number of pints of each to make 21 of green paints

First, calculate the total ratio.

$Total = 4 + 3$

$Total = 7$

The blue and the yellow pint can be represented individually as:

$Blue = \frac{4}{7} * Green$

$Yellow = \frac{3}{7} * Green$

Number of blue paint calculated last week is:

$Blue = \frac{4}{7} * 21$

$Blue = {4} * 3$

$Blue = 12$

$Yellow = \frac{3}{7} * Green$

$Yellow = \frac{3}{7} * 21$

$Yellow = {3} * 3$

$Yellow = 9$

Can somebody help me

saveliy_v [14]

Answer:

Y=5

You must first divide b (-10) by two and square it to know what you need to make a perfect square (25). You must then add or subtract the amount to make C (-13) into that number (add 38). Don't forget to do it on the other side too! (3 becomes 41) You then factor the left side. ((Y-5)^2=41) The result is your answer. (Y=5)

HELP PLEASE!! I DONT UNDERSTAND!!!!!!!!!! THANKS SO MUCH

8090 [49]

Hello, please consider the following.

We will multiply the numerator and denominator by

$4+\sqrt{6x}$

to get rid of the root in the denominator.

First of all, we cannot divide by 0, right? So, we need to make sure that the denominator is different from 0.

$4-\sqrt{6x} =0\sqrt{6x}=4\\\\\text{Take the square}\\\\6x=4^2=16\\\\x=\dfrac{16}{6}=\dfrac{8}{3}$

We need to take any x real number different from 8/3 then and simplify the expression.

Let's do it!

$\begin{aligned}\dfrac{4}{4-\sqrt{6x}}&=\dfrac{4(4+\sqrt{6x})}{(4+\sqrt{6x})(4-\sqrt{6x})}\\\\&=\dfrac{4(4+\sqrt{6x})}{(4^2-\sqrt{6x}^2)}\\\\&=\dfrac{4(4+\sqrt{6x})}{(16-6x)}\\\\&=\dfrac{2(4+\sqrt{6x})}{(8-3x)}\\\\&\large \boxed{=\dfrac{8+2\sqrt{6x}}{8-3x}}\end{aligned}$

Thank you
