Answer:
56
Step-by-step explanation:
Complete question:
Z varies jointly with x and y , x=2 and y=2, z=7. Find z when x=4 and y=8 using joint variation . (I need the problem worked out step by step)
If z varies jointly with x, and y, this is expressed as;
z = kxy
If z=7 when x= 2, y= 2
7 = k(2)(2)
7 = 4k
k = 7/4
To get z when x= 4 and y = 8
z = kxy
z =7/4 (4)(8)
z = 7*8
z = 56
Hence the value of z is 56
It’s 251 divided by 2 equals 5
For a parallelogram, we know that there are to pairs of angles that are the same and that all 4 angles add to 360.
2(5x-2)+2(48)=360
2(5x-2)+96=360
10x-4+96=360
10x+92=360
10x=268
x=26.8
Final answer: x=26.8
Hope this helps!
