Please help me "solve the system"&lt;br /&gt;&lt;br /&gt;<img src="https://tex.z-dn.net/?f=x%20%5E%7B2%7D%20%20%2B%20y%20%3D%207

Equation 1: x² + y = 7

Equation 2: 3x + 7 = 9

Use Equation 2 to solve for "x" and plug in "x" into Equation 1 to solve for "y".

3x + 7 = 9

3x = 2

x = \frac{2}{3}

*********************************

x² + y = 7

(\frac{2}{3})² + y = 7

\frac{4}{9} + y = 7

y = 7 - \frac{4}{9}

y = \frac{63}{9} - \frac{4}{9}

y = \frac{59}{9}

Answer: (\frac{2}{3}, \frac{59}{9})

To mix a particular shade of purple paint, red paint and blue paint are mixed in the ratio 5:3. To make 20 gallons of this shade
Gelneren [198K]

Answer:

quantity of red paint =  12.5 gallons

quantity of blue paint =  7.5  gallons

Step-by-step explanation:

Ratio of red and blue paint : 5:3

in ratio

a:b = ax:bx

let the

quantity of red paint be 5x

quantity of blue paint be 3x

then quantity of purple paint = quantity of red paint  + quantity of blue paint

                                                  = 8x

given quantity of purple paint is 20 gallons

thus,

8x = 20

x = 20/8 = 2.5

thus,

quantity of red paint = 5x = 5*2.5 = 12.5 gallons

quantity of blue paint = 3x = 3x*2.5 = 7.5  gallons
