Is there a picture or something because how many tiles does he wanna make
distance = rate * time.
distance is number of miles the car has traveled.
rate = number of miles per hour the car is traveling at.
time = number of hours the car has been driven.
let D = distance.
let T = time.
let R = rate
the general equation is D = R*T
as long as the car will always be driven at 55 miles per hour, you can substitute 55 for R and that becomes your constant.
The equation then becomes D = 55 * T.
example:
you drive 5 hours.
D = 55 * T = 55 * 5 = 275 miles.
If you drive at 55 miles per hour for 5 hours, you will have driven 275 miles.
Hope this helps!
The answer is 1/6 because 2/3-1/2 the command denominator is 6 so 2 goes in six 3 times then you do 3×1 =3 so you got 3/6 then you do 3 goes in 6 2 times then you do 2×2=4 and 4-3=1 so you get 1/6
15 x .30 = 4.50 discount 15-4.50= 10.50
10.50 x .40 = 4.20
Final cost of shirt 10.50-4.20 = $6.30
Answer:
length of side = 10x + 3
Step-by-step explanation:
The area of a square = s² ( s is the length of the side )
given
A = 100x² + 60x + 9 ← perfect square in the form
(a + b)² = a² + 2ab + b²
100x² = (10x)² ⇒ a = 10x
9 = 3² ⇒ b = 3
and 2ab = 2 × 10x × 3 = 60x, hence
100x² + 60x + 9 = (10x + 3)²
s = 
= 10x + 3 ← length of side
