Answer: z=1−x+w/r
Step-by-step explanation:
Subtract x from both sides.
z-w/r=1-x
Add w/r to both sides.
z=1−x+w/r

Answer:
Step-by-step explanation:
Multiplier: -175/3 Decrease: 23⅓ %
Step-by-step explanation: 75 = 250 - 3(d) d = -175/3 Y = 250 - (175/3)m
Where m is the no.
of months Y is the new value
(175/3)/250 × 100 = 70/3 %
Or 23⅓ %
Answer: It is B - 40
Step-by-step explanation:
40-23 = 17
Answer:
B
Step-by-step explanation:
Givens
a^2 + b^2 = c^2
a = 4x
b = x + 2
c = 3x + 4
Solution
(4x)^2 + (x + 2)^2 = (3x + 4)^3 Remove all the brackets.
16x^2 + x^2 + 4x + 4 = 9x^2 + 24x + 16 Collect like terms on the left
17x^2 + 4x + 4 = 9x^2 + 24x + 16 Subtract the terms on the right
8x^2 - 20x - 12 = 0
This factors into
(4x - 12)(2x + 1)
There are 2 answers
4x - 12 = 0
4x = 12
x = 12/4
x = 3
or
2x + 1 = 0
2x = - 1
x = - 1/2
You have to look at x = -1/2 carefully. The problem is that 4x = 4*(-1/2) = - 2 which is not possible in Euclidean Geometry.
So the only answer is x = 3
after subtracting the two numbers which would equal 207 you round which would 210
