Everything should add up to 100%. So do
20 + 40 + 10 + 5 = 75
Now subtract 75 from 100
100 -75 = 25
25%
It will be 5 pieces each to each person
Answer:
x = 5 /2 , y = 9 / 8
Step-by-step explanation:
x = 4y - 2 ....... (i)
x + 4y =7 ....... (ii)
Substituting eqn (i) into eqn (ii);
(4y - 2 ) + 4y = 7
4y - 2 + 4y = 7
8y = 7 + 2 = 9
y = 9 / 8
substitute y = 9 / 8 in eqn (i)
x = 4 (9 / 8) - 2
x = 9 / 2 - 2
x = (9 - 4 ) / 2
x = 5 / 2
Answer:
3x2+6x is a polynomial. Polynomials are algebraic expressions in which the variables have only non-negative integer powers. For example,: 5x2 - x + 1 is a polynomial.
