Solve the equation for W

Mathematics
1 answer:
OverLord2011 [107]3 years ago
5 0

Answer:

fourth option

Step-by-step explanation:

Given

\frac{2x-1}{y} = \frac{w+2}{2z} ( cross- multiply )

y(w + 2) = 2z(2x - 1) = 4xz - 2z ( divide both sides by y )

w + 2 = \frac{4xz-2z}{y} ( subtract 2 from both sides )

w = \frac{4xz-2z}{y} - 2

melomori [17]
First you subtract 8 from 26, which is 18. Then you divide 18 by 6, which is 3. x equals 3.

If y varies inversely as x and y=32 when x=3, find x when y=15
deff fn [24]
Y=kx, k is not equal to 0
when y=32,x=3, 32=3k
                           k=32/3
so y=32/3*x
when y=15, 15=32/3*x
                     x=45/32
