112.5 +1500 = 1612.5
False, they are both quadrilaterals though.
7 3/4.
i got this by adding 1/5+2/5=3/4 and then 4+3 which are the whole numbers.
Change the fractions to decimals for as easy algebraic solution.
.5 - (.2 + .25) = .05. Only 1/10 of the clay is left.
Answer:
x1= -4, x2 = 7
Step-by-step explanation:
Move expression to the left-hand side:
1/4x-3/4-7/x=0
Write all the numerators above a common denominator:
x^2 - 3x - 28 /4x =0
When the quotient of expressions equal 0, the numerator has to be 0
x^2 + 4x - 7x - 28 = 0
x(x+4) - 7(x+4) =0
(x+4) × (x-7) =0
Separate into possible cases:
x+4=0
x-7=0
