(0.12,∞) is the correct answer
Answer:
Each bouquet included 2 foil balloons and 8 latex balloons.
Step-by-step explanation:
Let f represent the number of foil balloons in each bouquet. Then 10-f is the number of latex balloons. The problem statement tells us the cost of all of the bouquets is ...
18(1.94f +0.17(10-f)) = 94.32
We can divide by 18 to get ...
1.94f +1.70 -0.17f = 5.24
1.77f = 3.54 . . . . . . . . . . . . subtract 1.70
f = 3.54/1.77 = 2 . . . . . . . . divide by the coefficient of f
The number of latex balloons is 10-2 = 8.
Each bouquet included 2 foil and 8 latex balloons.
4x + y = 12
Get y by itself
Subtract 4x
y = -4x + 12
Since you know what y is, you can plug the value into the second equation
6x + 2(-4x + 12) = 18
6x - 8x + 24 = 18
-2x = -6
x = 3
Plug the value 3 into x for y = -4x + 12 in order to find y
-4(3) + 12 = y, y = 0
Solution: x = 3, y = 0
Answer:
Step-by-step explanation:
2x + 10 = 28
Bringing like terms on one side
2x = 28 - 10
2x = 18
x = 18/2 = 9
Answer:
1900
Step-by-step explanation:
1 kg = 1000g
1.2kg = x
<u>1</u><u> </u><u>kgx</u> = <u>1</u><u>2</u><u>0</u><u>0</u><u> </u><u>kg.g</u>
1kg. 1kg
x = 1200 g
1 decagram = 10g
40 decagram = x
<u>1</u><u> </u><u>dg.x</u> = <u>4</u><u>0</u><u>0</u><u> </u><u>dg.g</u>
1 dg. 1 dg
x = 400g
so the total= 1200g +300 + 400g=1900g
without the unit = 1900
