Answer:
r = -29/20 or r = -1.45
Step-by-step explanation:
I believe you are saying that the equation is -2 1/4 = r - 4/5. If so, then I would solve it in this way:
-2 1/4 = r - 4/5
-9/4 = r - 4/5
-9/4 (20) = r (20) - 4/5 (20)
-45 = 20r - 16
20r = -29
r = -29/20
r = -1.45
Check:
-2 1/4 = r - 4/5
-9/4 = r - 4/5
-2.25 = r - 0.8
-2.25 = -1.45 - 0.8
-2.25 = -2.25
-9/4 = -9/4
Answer:
answer is 3
there are two ways to solve it. I hope you understand.
Answer:
Theory
Step-by-step explanation:
Take any 18 objects
For example in this case
Take 18 chocolates
means one sixth , which practically means how many groups of 6 can be formed
So, Try to divide 18 into groups of 6
Count how many such groups are formed(it will be 3)
So one sixth of 18 is 3
That is, 18 comprises of 3 groups, each group containing 6 chocolates
Answer:
False
Step-by-step explanation:
If this number is larger than 6, then its square is larger than 36.
If x > 6, then x² > 36
The number is not larger than 6.therefore Its square is not larger than 36.
x ≤ 6; therefore, x² ≤ 36
-7 is < 6; however -7² > 36 as -7² = 49
