The answer is $6.00 because you multiply 15 by .4
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.

Solving for X:
1) y=-8x+6.5 y=-4x+11
2) -8x+6.5=-4x+11
3) -8x=-4x+11-6.5 (Subtract 6.5 from both sides)
4) -8x+4x=11-6.5 (Add 4x to both sides)
5)-4x=4.5
5)x=-1.125
Solving for Y:
y=-8(-1.125)+6.5
y=9+6.5
y=15.5
y=-4(-1.125)+11
y=4.5+11
y=15.5
x=-1.125
y=15.5
or
(-1.125,15.5)
Answer:
21, 23, 25
Step-by-step explanation:
Ok, so this one may seem a little tricky, so I'll try to explain it as best as I can. :)
So because they are consecutive odd numbers, that means they are odd numbers that are one after the other. This means each number is 2 apart from the next. So by using this, we know that there is a difference of 6 between the highest and lowest number. Now let's try and make an equation:
3o + 6 = 69
Now in order to get O by itself we have to subtract 6 from both sides:
3o = 63
Now we just have to divide by three on both sides:
o = 21
So now, we know that the lowest number is 21, but we have to add 2 to get 23, and then another 2 to get 25.
Hope this helps :)
