Answer:
3. 4+2+x and (4+2)+x
4. 7y-10
Step-by-step explanation:
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 = 
*********************************
x² + y = 7
()² + y = 7
+ y = 7
y = 7 -
y = 
-
y = 
Answer: (, )
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
