Answer:

Answer:

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

WILL MAKE BRAINLIEST
Tasya [4]
If Hannah gives her younger sister 3 shirts, it does not matter what order she hands them to her. No matter the order, it will still be the same group of 3 shirt. Since order is not important this problem can be solved using a combination. 
Specifically, we are asked to find 8C3 (sometimes called "8 choose 3"). This is a fraction. In the numerator, we start with 8 and count down 3 numbers. In the denominator, we start with 3 and count all the way down to 1.
your answer is 56
