Answer:
Step-by-step explanation:
Given,
The number of litres consumed by car in (x+20) km = 6,
So, number of litres consumed by car in 1 km = 
,
Now, number of litres consumed by car in 100 km = 100 × litres consumed by car in 1 km
Hence, the rate of fuel used by his car would be 
litres per 100 km.
Answer:
B. y ≤ |x – 2| + 4
Step-by-step explanation:
Shading is <em>below</em> the <em>solid</em> line, so the appropriate relation symbol is "less than or equal to" (≤).
Shading is <em>below</em> when y values less than those on the line are part of the solution set.
The line is <em>solid</em> when it is part of the solution set (dashed, otherwise). It is part of the solution set when y-values <em>equal to</em> those on the line are solutions to the inequality.

Hola!
Circumference of circle is 12.56 cm
Means,
2 × π × r = 12.56
r = 12.56 × 3.14 × 2
r = 1.999 cm
According to Question,
Area of Circle:
π × r²
3.14 × 1.99 × 1.99
12.547 cm² = 12.56 cm² (approximately.)
Hence,
Area of Circle is 12.56 cm²
hope it helps!
P = 2L + 2W, keep that in mind (W=width, L=length)
Just fill it in. 82=2(5+2w) + 2w. First solve for w.
82 = 10+ 10w + 2w,
82 = 10 + 12w. Now subtract the 10 from both sides, and get:
72 = 12w, now divide both sides by 12, and get:
6 = w.
W is 6.
Now to solve for L, go back to the problem we had, L = 5 + 2w. Fill in w,
L = 5 + 2(6), and then it is L = 5 + 12.
It is a simple addition equation now.
L = 17, W = 6
