Answer:
9/24
Step-by-step explanation:
First, find the LCD: 24.
24/8=3. 3*5=15. So, 2 5/8 becomes 2 15/24.
24/12=2. 2*3=6. So, 2 3/12 becomes 2 6/24.
2 15/24 - 2 6/24 = 9/24.

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
Answer:
23 matches
Step-by-step explanation:
If the 5th grade team wins 2/5 matches, thats equal to 8/20, and 4th graders win 15/20, so together they win 23 matches out of 40
