If you would like to solve 32 + 5yi = 16x - 40i for y, you can do this using the following steps:
<span>32 + 5yi = 16x - 40i
</span>5yi = 16x - 40i - 32 /5
yi = 16x/5 - 8i - 32/5 /i
y = 16x/5i - 8 - 32/5i
The correct result would be <span>y = 16x/5i - 8 - 32/5i.</span>

4x -3y + z = -10...............(1)
2x +y + 3z = 0...............(2)
-x +2y - 5z = 17...............(3)
First we multiply 3*(2) and add it to (1)
6x +3y +9z =0..................+(1)..................> 10x + 10z = -10......(4)
Then we multiply -2*(2) and add it to (3)
-4x -2y -6z =0 ...................+(3)................> -5x -11z = 17...........(5)
Multiply 2*(5) and add it to (4)
-10x -22z = 34...................+(4).................> -12 z = 24 ..............>>> z = -2
Substitute z in (4)............> 10x +10(-2) = -10.............................>>> x = 1
Substitute x and z in (2).....> 2(1) +y + 3(-2) = 0..................>>> y = 4
Solution (x,y,z) = (1,4,-2)
The anwers is B hope it helps please give me Brainly
We have to calculate how would it take for a red kangaroo to jump 2 km, if he jumps at a rate of 40 km/h.
Formula for the velocity is: v = d / t, where d stays for the distance and t stays for the time.
Therefore: t = d / v
t = 2 km / 40 km/h
t = 0.05 h = 3 minutes
Answer:
It would take 3 minutes.
