Answer:
6
Step-by-step explanation:
1. re-write the given system:
cx+3y=c-3; => y= -cx/3 +(c-3)/3
12x+cy=c; => y= -12x/c+c/12
2. according the condition the rule for the parallel graphs is:
-c/3= -12/c
3. to calculate the unknown 'c':
c²=36; ⇔c=±6
Answer:
92 inches
Step-by-step explanation:
When a tire's size = P220/65 R 18, it means that:
- the rim is 18 inches wide (or 457 millimeters)
- the width of the tire is 8.7 inches (or 220 millimeters)
- the sidewall of the tire is 5.65 inches (or 144 millimeters)
- the 65 shows the relationship between tire width and sidewall (65%)
the total diameter of the tire = 5.65 + 18 + 5.65 = 29.3 inches
the circumference = 2 x π x radius or diameter x π = 29.3 x 3.141592 = 92 inches
Answer: 8 Units
btw have a good day :)
X = y - 8
Step by step
Y = x + 8
x + 8 = y
-8 -8
x = y - 8
