We have two equations d=55t and d=20g
The left sides of this equations are the same than the right sides are equal too
a) 55t=20g
b) g=(55/20)t
c) t=6h => g=(55/20) *6 = 165/10=16.5 gallons
d= 55t= 55*6=330 miles or d=20g=20*16.5=330 miles
Good luck!!!
Answer:
Perimeter, P = (24d+0.8) cm
Step-by-step explanation:
Given that,
Width of rectangle, B = (4.4d−4.3) cm
Length, l = (7.6d+4.7)
Perimeter is equal to the sum of all sides. A rectangle have 4 sides. The opposite sides of a rectangle are equal. So,
Perimeter = 2(L+B)
P = 2[(7.6d+4.7)+(4.4d−4.3)]
Collecting like terms
P = 2[(7.6d+4.4d)+(4.7−4.3)]
P=2(12d+0.4)
⇒ P = 24d+0.8
So, the expression for the perimeter of the rectangle is (24d+0.8) cm.
There are 16 oz. per 1 pound, so you have to multiply 21 by 16, which equals 336. Then you divide the 336 oz into 44 baskets. 336 / 44 = 7.64 oz
-5+5 is the pair that the sum is 0
