Get common denominators, and solve for each expression
7/5 - 3/4 = 28/20 - 15/20 = 13/20
1/4 + 2/5 = 5/20 + 8/20 = 13/20
These two fractions are equivalent
Answer:
The first one: 19/15a
second one: b²-4ac = D
Step-by-step explanation:
for first one: take LCM and solve
for second one: you square the expression on both sides then b²= D + 4ac, then when you take 4ac to the left hand side, it becomes b²-4ac= D
Answer:
No
Step-by-step explanation:
Think of it like this. 6/10 is 60% and 5/20 is 25%. These two values aren't the same.
2 is the answer you're looking for.
2*7=14
14-8=6
2*3=6
Answer:
So F=19
Step-by-step explanation:
8=f-(13-2)
8=f-11
+11 +11 You plus 11 by both sides
19=f
You can check you answer by plugging it in
8=19-(13-2)
your answer would still be 19
