Marcus made a mistake in Step 2. 5/2.5 is 2 not 3.
-11 -(-42) A double negative makes a positive
-11 + 42
31
Answer:
3.75 or 15/4
Step-by-step explanation:
8x+5=35
Subtract 5 from the left side to cancel it out, do the same thing to 35.
8x=30
Divide 8x by 8 to get x alone, do the same thing to 30.
x=3.75, or once you simplify 30/8, you get 15/4.
Answer:
<u>Equations for each salesman:</u>
- A. p(s) = 65s
- B. p(s) = 40s + 300
- C. p(s) = 900
<u>When s = 0, s= 1, s = 10 each of the gets paid:</u>
- A. p(0) = 0, p(1) = 65, p(10) = 650
- B. p(0) = 300, p(1) = 340, p(10) = 700
- C. p(0) = p(1) = p(10) = 900
<u>The above numbers as ordered pairs:</u>
- <u> A B C </u>
- s = 0 | (0, 0) | (0, 300) | (0, 900)
- s = 1 | (1, 65) | (1, 340) | (1, 900)
- s = 10 | (10, 650) | (10, 700) | (10, 900)
Answer is 4 and I will attach a photo of my work
Step-by-step explanation:
C = 2πr = 53.38cm
r = C / 2π = 53.38cm / 2π = 53.38/ 6.283185307179586 = 8.4956cm
A = πr^2 = π × (8.4956cm^)2 = 226.4cm^2
