the answer is 5 since the sides are kinda equal to each other it looks like
Answer:
Step-by-step explanation:
Each pitcher is 314 liters
Therefore quantity in 4 pitchers is = 314 x 4 = 1256 liters
Answer:
Step-by-step explanation:
£21000/7=3000
I got seven by adding 2 and 5
3000 times 2=6000
3000 times 5 = 15000
6000:15000
6000 for the venue
15000 for the band

- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
x - 2y = 12
5x + 3y = -44
<u>Step 2: Rewrite Systems</u>
x - 2y = 12
- [Multiplication Property of Equality] Multiply everything by -5: -5x + 10y = -60
<u>Step 3: Redefine Systems</u>
-5x + 10y = -60
5x + 3y = -44
<u>Step 4: Solve for </u><em><u>y</u></em>
<em>Elimination</em>
- Combine 2 equations: 13y = -104
- [Division Property of Equality] Divide 13 on both sides: y = -8
<u>Step 5: Solve for </u><em><u>x</u></em>
- Define original equation: x - 2y = 12
- Substitute in <em>y</em>: x - 2(-8) = 12
- Multiply: x + 16 = 12
- [Subtraction Property of Equality] Subtract 16 on both sides: x = -4
