-9/4v + 4/5 = 7/8;
First, you subtract 4/5 from each side to have variable v on a side and numbers on the other:
-9/4v = 7/8 - 4/5;
-9/4v = 35/40 - 32/40;
-9/4v = 3/40;
Then you divide each side to get the variable v alone on a side, and one number on the other:
V= (3/40) / (-9/4);
Dividing to fractions is equal to multiplying the first one by the inverse of the second:
V= (3/40) * (-4/9);
V= -12/360;
V= -1/30;
You can re-check your answer (very important):
(-9/4)*(-1/30)+4/5=7/8;
The answer has been approved.
Hope this helps! :)
The answer should be 65. The number be added is doubled. +4,+8, +16, +32 So 32+33=65 65+64=129
The word that describes it is congruent
To find the number halfway between 60 and 75, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 60 and 75 into our formula, we get:
(60 + 75)/2 = 67.5
Thus, the number halfway between 60 and 75 is 67.5.
