Answer:
10.
Step-by-step explanation:
I am assuming that z is a whole number.
160z = x^2
z = x^2/ 160.
160 = 2*2*2*2*2*5
To make this a perfect square we multiply by 2 * 5
- this gives us 1600.
z = 1600/160 = 10.
Answer: 6
Step-by-step explanation: -8 x -8 = 64
64 - -58 = 6
Ten plus five equals 15. 8 plus 2 = 10.
-1/2+2 (-9/4)
Reduce the fraction by dividing the numerator and denominator by 2
-1/2+1 (-9/2)
Multiply the values
-1/2 - 9/2
Bring the values to the common denominator
(-1-9)/2
Calculate the difference
-10/2
Reduce the fraction by dividing the numerator and denominator by 2
-5.
