Answer:
5 yards
Step-by-step explanation:
Since the area is 25 yards and 5 x 5 is 25. You know that the length of one side is 5 yards! A = 25 and P = 20.
Answer:
1 metre = 100 centimeters
Therefore 2 meters = 200 centimeters
A.T.Q.
More sprinkler pipe Alex needed = 200 centimetres - 89 centimeters
= 111 centimeters
100 centimeters = 1 metre (As above)
Therefore, 89 cm = 111/100
= 1.11 metres

Answer:
15%
it is the best because it is the option that offers the lowest price
Step-by-step explanation:
900 reduction : 6975 - 900 = 6075
15% discount :
0.15 x 6975 = $1046.25
6975 - $1046.25 = 5928.75
7/8 x 6975 = 6103.13

- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
15s + t = 5
4s = 3t + 34
<u>Step 2: Rewrite</u>
15s + t = 5
- Subtract <em>t</em> on both sides: 15s = -t + 5
- Multiply both sides by 3: 45s = -3t + 15
<u>Step 3: Redefine Systems</u>
45s = -3t + 15
4s = 3t + 34
<u>Step 4: Solve for </u><em><u>s</u></em>
<em>Elimination</em>
- Combine equations: 49s = 49
- Divide 49 on both sides: s = 1
<u>Step 5: Solve for </u><em><u>t</u></em>
- Define equation: 15s + t = 5
- Substitute in <em>s</em>: 15(1) + t = 5
- Multiply: 15 + t = 5
- Isolate <em>t</em>: t = -10
