Divide the first fraction by 2 you get 4/11
divide the second fraction by 2 you get 6/7
Answer:
$53.33
Step-by-step explanation:
40/1 - .25
40/.75 = $53.33
Y=x^2+3x+4
y-x=7
x^2+3x+4-x=7
x^2+2x+4=7
(factor) x^2+2x-3=0
(x+3)(x-1)=0
X= -3 and X=1
(Plug x in for y)
Y= 1^2+3(1)+4
Y=8
(Check your answer on the second equation)
8-1=7
7=7 (Which is the solution)
Answer:
To solve a literal equation means to express one variable with respect to the other variables in the equation.
Step-by-step explanation:
1.
Determine which variable you need to isolate. Isolating a variable means getting the variable on one side of an equation by itself.
2.
Use algebra to solve for the desired variable. Use inverse operations to cancel variables on one side of the equation and move them to the other side. 3.
Keep the equation balanced. Whatever you do to one side of the equation, you must also do to the other side
