Answer:
There are 4 different terms in the simplified expression of [2x + 3xy -(x + y) + 2].
Step-by-step explanation:
We are asked to count the number of terms in the simplified expression of [2x + 3xy -(x + y) + 2].
Now, [2x + 3xy -(x + y) + 2]
= 2x + 3xy - x - y + 2
= x + 3xy - y + 2
= x - y + 3xy + 2
Therefore, there are 4 different terms in the simplified expression of [2x + 3xy -(x + y) + 2]. (Answer)
Answer:
Please check the explanation.
Step-by-step explanation:
a)
As there are 1000000 units in 1 million
i.e.
1 million = 1000000 units
A house as purchases for $6780000.
Thus, the purchase price in million will be:
6780000/1000000 = 6.78 million
b)
purchase price in millions nearest to an integer
As the number we are rounding is followed by 7, so will be round the number up.
Therefore,
$6780000 rounded to the nearest million = $7,000,000
Answer:
1 < x
Step-by-step explanation:
6x - 12 < 8x- 14
Subtract 6x from each side
6x -6x- 12 < 8x-6x- 14
-12 < 2x -14
Add 14 to each side
-12 +14 < 2x
2 < 2x
Divide each side 2
2/2 < 2x/2
1 < x
Answer:
4 tubes of paint
Step-by-step explanation:
Carmen needs 2 paint brushes which cost $6.70, so,
6.70+6.70= 13.4
So we can take Carmen's total winnings, $35, and subtract the cost of the paint brushes.
35-13.4=20.6
After buying two paint brushes, she would have $20.60 left for paint. Each paint cost $4.80, so we need to find out how many 4.8 we can get out of 20.6. We can divide to find this.
20.6/4.8=4.29166667
We take the whole number, 4, because obviously she can't buy have a tube.
We then have our answer, Carmen can get 4 tubes of paint.
So make them all x
Jenny = x
Ali = x+5
Eric - 2x
2x + x + 5 + x = 97
4x = 97 - 5
x = 23
Jenny has 23
]Ali has 28
Eric has 46
