Answer:
Step-by-step explanation:
"length is 4 meters less than 2 times the width"
L = 2W+4
"perimeter is 40 meters"
2L+2W = 40
L+W = 20
(2W+4) + W = 20
3W + 4 = 20
W = 16/3 meters
Answer:
Step-by-step explanation:
The process here is to find out how far the tire travels in one rotation, then multiply that by 100. That means we need to find the circumference of the tire since the circumference tells us how far around the outside of the tire it is in inches.
C = πd where d is the diameter of the tire.
C = 3.1415(26) so
C = 81.679 inches. Multiply that by 100 to get
8167.9 inches, which in miles is a little over 1.5 miles
A ton is 2,000 pounds. So 40,000 pounds would be 20 tonnes.
Answer:
y=2x+17
Step-by-step explanation:
y-y1=m(x-x1)
y-1=2(x-(-8))
y-1=2(x+8)
y=2x+16+1
y=2x+17
Answer: (x−2)(x−4)
Step-by-step explanation: Let's factor x2−6x+8
x2−6x+8
The middle number is -6 and the last number is 8.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get -6
Multiply together to get 8
Can you think of the two numbers?
Try -2 and -4:
-2+-4 = -6
-2*-4 = 8
Fill in the blanks in
(x+_)(x+_)
with -2 and -4 to get...
(x-2)(x-4)
