Answer:
Because the base of this expression is not same.
(a) Without solving the equation we can't determine whether its true or false.
(b) If x = 3
4x + 1 = 2x + 5
4(3) + 1 = 2(3) + 5
12 + 1 = 15 + 5
13 = 20
No, if x = 3, the equation will not be true.
(c) 4x + 1 = 2x + 5
4x - 2x = 5 - 1
2x = 4
x = 4/2
x = 2
This shows that x = 2 makes the equation true.
27.5 / 3.5 = 7.86; The average yearly snowfall was 7.86 inches.
-6 belongs to a set of real numbers and also a set of rational numbers.
Real numbers are all integers: positive and negative whole numbers. So -6 is a real number.
Rational numbers are all numbers that can be expressed as a fraction i.e numerator/denominator form. So -6 = -6/1 which is a rational number.
