Answer:
c.) P=4s
Step-by-step explanation: All sides of a square are equal, therefor, since there are 4 sides, then 4 times s is the answers.
1 hour = 1/4 inch
6 hours = 1/4 x 6 = 6/4 = 1 1/2 inches
Answer: 1 1/2 inches
Answer:
See below
Step-by-step explanation:
<u>1. Solve for y</u>
- x = 0
- z = 5x + 3 ⇒ z = 5*0 + 3 = 3
- 4y + 6z = 26 ⇒ 4y + 6*3 = 26 ⇒ 4y = 26 - 18 ⇒ 4y = 8 ⇒ y = 2
- y = 2
- Option B
<u>2. Solve for x</u>
- -7x - y = 6 ⇒ y = -7x - 6
- x - 3y = 18 ⇒ x - 3(-7x - 6) = 18 ⇒ x + 21x + 18 = 18 ⇒ 22x = 0⇒ x = 0
- x = 0
- Option C
<u>3. Solve for x</u>
- y = -4
- z = 3x - 12
- 3x + 3y = -6 ⇒ 3x + 3(-4) = -6 ⇒ 3x = 12 - 6 ⇒ 3x = 6⇒ x = 2
- x = 2
- Option B
<u>4.....................</u>
- 0 = 1
- The equation is false so it means no solution
<u>5...................... </u>
- 0 = 0
- The equation is true so it means infinitely many solutions
