Answer: The space given up by the students is 1/4 of the total space.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
<em> Students must give up half of the exhibit space to the other school.</em> So, we have to divide 5/10 by 2.
5/10 ÷ 2/1 = (5x1 ) / (10 x2 ) = 5 /20
Simplified (by 5) = 1 /4
The space given up by the students is 1/4 of the total space.

Answer:
Step-by-step explanation:
- Let (applicable to all three lines below)
- Hard candy = x kg with price $1.60/kg
- Gummy worms = y kg with price $2.20/kg
- Total weight = 50 kg with mixed price $1.75/kg
<u>Required equations:</u>
- x + y = 50 total weight
- 1.60x + 2.20y = 50*1.75 total price
=========================================
<u><em>Note</em></u><em>. It says don't solve but the solution below for those who is interested to know the answer.</em>
<u>Simplify the second equation and solve by substitution x = 50 - y:</u>
- 1.6(50 - y) + 2.2y = 87.5
- 80 - 1.6y +2.2y = 87.5
- 0.6y = 7.5
- y = 7.5/0.6
- y = 12.5
<u>Find the value of x:</u>
<u>Hard candy</u> = 37.5 kg and <u>gummy worms</u> = 12.5 kg
-3x - 4y = 2
<u>8y</u> = <u>-6x - 4</u>
8 8
y = -0.75x - 0.5
-3x - 4(-0.75x - 0.5) = 2
-3x + 3x + 2 = 2
0x + 2 = 2
<u> - 2 - 2</u>
<u>0x</u> = <u>0</u>
0 0
x = 0
-3(0) - 4y = 2
0 - 4y = 2
<u>- 0 - 0</u>
<u>-4y</u> = <u>2</u>
-4 -4
y = 0.5
(x, y) = (0, 0.5)
