If you would like to know how many cups of fruits are in the salad, you can calculate this using the following steps:
3/8 cup of raisins + 7/8 cup of oranges + 3/4 cup of apples = 3/8 + 7/8 + 3/4 = 10/8 + 3/4 = 5/4 + 3/4 = 8/4 = 2 cups of fruits
The correct result would be 2 cups of fruits.
Answer:
X = 9,X= -5, a = 2, b = -13
Step-by-step explanation:
For (1),
Using Cross-factorization,
it can be reduced to (X - 9)(X + 5) = 0
Equate each factor to 0:
we have X = 9 and X = -5
For (2),
It is the case of completing the Square,
add 4 so we get the completed square ( we want the form X^2 + 2a + a^2)
(X^2 + 4X + 4) - 9
can be simplified to (X+2)^2 -9
However since we added 4 it means we have to subtract 4
So it becomes (X+2)^2 -9 -4
= (X+2)^2 -13
Answer:
I believe the answer is D.
94
(85+89+92+x)/4 = 90
(266+x)/4 = 90
(Multiply by 4 on each side to get rid of it)
266+x=360
(subtract 266 from each side)
x = 94
You need more information to answer this question. Is there a table or percentage for that age group?
