Answer:
35
Step-by-step explanation:
Here we see 5 black keys for every 7 white keys.
So the ratio is 5:7
If we need 49 white keys, find the amount we scale the original ratio by:
49/7 = 7
So we are scaling by a factor of 7.
The number of black keys would be 5 * the scale of 7. = 35
So there should be 35 black keys.
Answer:
The number of flower pots that were sold is 50
Step-by-step explanation:
Let x represent the number of flower pots that the store owner bought and sold.
A store owner bought some flower pots for $1,200. Therefore, the cost price for each flower pot would be
1200/x
The flower pots were sold for $2,700, with a profit of $30 per pot. The means that the selling price of each flower pot would be
2700/x
Profit = selling price - cost price
Therefore
2700/x - 1200/x = 30
Multiplying both sides of the equation by x, it becomes
2700 - 1200 = 30x
30x = 1500
x = 1500/30 = 50
5x+4+8x-3=79
13x=79-1
x=6
DBC=34
ABC=45
6x+20+2x+4 = 180
8x = 156
x=19.5
TQS=137
RQS=43
For this case we must indicate the factors of the following expression:
To factor we must find two numbers that when multiplied result in -20 and when added, result in -12.
There are no two numbers that meet this condition. Thus, the expression is not factorizable with rational numbers.
Answer:
The expression is not factorizable with rational numbers.
