Answer:
12 = 2.5h + 4
Step-by-step explanation:
Answer:
-2
Assumption:
Find the value of x such that
.
Step-by-step explanation:



Combine like terms:

This is not too bad too factor on the left hand side since 2(2)=4 and 2+2=4.


So we need to solve:

Subtract 2 on both sides:

Let's check:






0 was the desired output of
.
Answer:
21:27 and 14:18
Step-by-step explanation:
We can solve this by using common factors
one of the common factors of 54 and 42 is 3
42/3=14
54/3=18
so one of the ratios is 14:18
another common factor is 2
42/2=21
54/2=27
so another ratio is 21:27
The expanded form is adding all the digits so the answer is
700+50+7+0.9+0.02+0.003
