If you're solving for W, your answer is w = 2 1/6
First, we would simplify our fractions:
w + 2/3 = 2 5/6 =
w + 2/3 = 17/6
Lastly, we subtract 2/3 on both sides of the equation:
w + 2/3 - 2/3 = 17/6 - 2/3 =
w = 13/6 or w = 2 1/6
2y - x = 5
x^2 + y^2 - 25 = 0
x = 2y - 5
(2y-5)^2 + y^2 - 25 = 0
(2y-5)(2y-5) + y^2 - 25 = 0
4y^2 - 20y + 25 + y^2 - 25 = 0
5y^2 - 20y = 0
y = 0 , y = 4
x = 2y - 5 , when y = 0
x = - 5
x = 2y - 5 , when y = 4
x = 8 - 5
x = 3
Answer:
Step-by-step explanation:
b = 2/3
a = 7/3
b)
Cross multiply,
2b + 1 = a*(3b - 1)
2b + 1 = a*3b - 3*a
2b + 1 = 3ab- 3a
2b = 3ab - 3a - 1
2b - 3ab = -3a - 1
b(2 - 3a) = -3a - 1
2(4+39) = 39 + 4 = 43
43 x 2 = 86
-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.
