Answer:

Step-by-step explanation:

→ First look at the first term of each expression and see if they can be simplified, and they can

→ Now look at the a terms, since a larger one is at the top, you subtract

→ Now simplify the b and c terms

Make it an improper fraction with two as the denominator, and you'll get 9/2. There are 9 halves in 4 1/2 meters
Answer:
x = number of bicycles = 35
y = number of cars = 55
Step-by-step explanation:
Let
x = number of bicycles
y = number of cars
x + y = 80 (1)
2x + 4y = 270 (2)
From (1)
x = 80 - y
Substitute x = 80 - y into (2)
2x + 4y = 270 (2)
2(80 - y) + 4y = 270
160 - 2y + 4y = 270
- 2y + 4y = 270 - 160
2y = 110
y = 110/2
y = 55
Substitute y = 55 into (1)
x + y = 80 (1)
x + 55 = 80
x = 80 - 55
x = 35
x = number of bicycles = 35
y = number of cars = 55
Answer:
1.2%
Step-by-step explanation:
0.012 = 12/1000
to express it as %
12/1000 * 100
= 1.2%
Start with the equation,
V = 2s^3
Now substitute s with 3.5 units and evaluate the expression.
V = 2 * (3.5 units)^3
V = 2 * 42.875 units^3
V = 85.75 units^3
Answer: The volume is 85.75 cubic units
