Solve the following systems of equations. 2^(2x+y−1) = 32 4^(x−2y) = 2

Rina8888 [55]

Answer:(x,y)=(2.5,1)

Step-by-step explanation:

Given

$2^{2x+y-1}=32$

$2^{2x+y-1}=2^5$

thus on comparing

2x+y=6------1

$4^{x-2y}=2$

$2^{2(x-2y)}=2$

On comparing exponent of 2

$x-2y=\frac{1}{2}$ ------2

we get x=2.5

substitute x in 1

y=1

(x,y)=(2.5,1)

Julie has 50$ which is eight dollars more than twice what john has. How much does john have

nydimaria [60]

Answer:

John has $21.

Step-by-step explanation:

Let John's "wealth" be w. Then 2w+8 = 50, or 2w = 42, or w = 21.

John has $21. Eight more than twice this is 42+8 = 50, as expected.
