Multiply both sides by 100
1.55y -(5y-17)/100 * (100) = (0.02)*(100)
1.55y -(5y-17) = 2
Simply both sides of the equation
-3.45y + 17 = 2
Subtract 17 from both sides
-3.45y + 17-17 = 2-17
-3.45y = -15
Divide both sides by -3.45.
-3.45y = -15
-3.45 -3.45
y = 4.347826
Answer:
you use the FOIL method
Step-by-step explanation:
First
Inner
Outer
Last
you just distribute the numbers to all of the others then simplify.
ex.
(x+4)^2
(x+4)(x+4)
x^2+4x+4x+16
x^2+8x+16
in this, x times x is x^2. then x times 4 is 4x and 4 times x is 4x and 4 times 4 is 16. then combine like terms
