Use the method of simultaneous equations and you can solve it. Once you do that you should get (-4,9)
Answer:
A. $3.63
Step-by-step explanation:
You can choose the correct answer simply by estimating.
The almonds are about $5.50 for each of the 2 kg, so will total about $11. Since the total amount paid is just over $25, the amount paid for cashews is about $25 -11 = $14.
That amount pays for 4 kg of cashews, so 1 kg will be half of half that amount, or about $3.50 -- certainly, less than $7.26.
_____
If you want to write an equation, you can write ...
2(5.49) +4(c) = 25.50
4c = 14.52 . . . . . . . . . . . . subtract 10.98
14.52/4 = c = 3.63 . . . . . divide by the coefficient of c
1 kg of cashews has a price of $3.63.
Answer:
19/15
Step-by-step explanation:
1 2/3=5/3
So 5/3 - 2/5 ( + - is -)
Making the denominator equal we get
(25-6)/15=19/15
Answer: 2 terms
Step-by-step explanation:
There are two terms because
One is __x the other is the constant
9x + 4 - 3x + 7
6x + 4 - 7
6x - 3 has two terms
