Answer:
33.75 miles in 45 minutes,
45 miles in an hour
Step-by-step explanation:
45 minutes: 2 1/3= 7/3 ---> 7/3*3=7,
1 3/4= 7/4 ---> 7/4*3=5.25
car travels 5.25 miles for every 7 minutes,
45/7*5.25= 33.75 miles
1 hour (60 minutes):
using that the car travels 5.25 miles for every 7 minutes,
60/7*5.25= 45 miles
Hope that makes sense!
Answer:
Step-by-step explanation:
1)
total area = rectangle area + 2 triangle area
= length * width = 2 ( * base * height )
= 7.5 * 6 + 2 ( * 3 * 4 )
= 57 ft²
2)
separate it into two rectangles:
length * width + length * width
6 * 2 + 9 * 4
48 cm²
3)
parallelogram area = base * height
= 20 * 25
= 500 in²
Answer:
x=-11
Step-by-step explanation:
3+3x=6=-24
3x+9=-24
3x=-33
x=-11
The sum of a number and three is (n+3)
The difference of 8 and the number is (8-n)
And if we multiply them we get:
(n+3)(8-n) if you wanted it expanded...
8n-n^2+24-3n
-n^2+5n+24
