Answer:
Metallic Balloons = 74
Bunches of Helium Balloons = 38
Step-by-step explanation:
The question basically asks for the number of "metallic balloons" sold and the number of bunches of "helium balloons" sold.
We will do it in our way. Let B be number o metallic balloons and H be number of bunches of Helium balloons.
Since Metallics cost 2 each and Heliums cost 3.5 per bunch and totaled sales is 281, we can write and equation as:
2B + 3.5H = 281
and, since they sold 36 MORE metallic than helium ,we can write an equation as:
B - 36 = H
We can put 2nd equation in 1st one and solve for B first:
B = 74
Now, we find H:
H = B - 36
H = 74 - 36 = 38
H = 38
Answer:
x-y
Step-by-step explanation:
Combine like terms
2/3x + 1/3x - 3y + 2y
1x - 1y
x - y
1/6 = 1/2 hr
2/6 = 1 hr
6/6-1/6 = 5/6 left of the test
2/6 + 2/6 = 4/6 = 2 hours
4/6 + 1/6 = 2 + 1/2 = 2 1/2
so 2 1/2 more hours
24-8 (difference) = 16
16/ 2 numbers = 8 is smallest number
8 + 8(difference) = 16 is largest number
The smaller number is 8
