The answer is 40cm = 2000km
The unit rate is 50km per cm, so 40cm is 40*50 km
40*50= 2000km
5 because if you plug in to get the equation 3x+20=7x then subtract 3x from both sides and divide by 4 from both sides

Answer:
18
Step-by-step explanation:
To answer, you want to follow PEMDAS:
P = parentheses
E = exponents
M = multiplication
D = division
A = addition
S = subtraction
So, the first step is parentheses, therefore we do whatever is inside the parentheses, and that is multiplying:
(2 * 3) + (3 * 4) =
6 + 12
Now, because there are no exponents, we cannot multiply anymore, and we cannot divide, we can add:
6 + 12 =
18
And that is our final answer!
Hope this helps :)
