Answer:
a. 12.8 cm b. 3.125
Step-by-step explanation:
To find any scale drawing use a proportion with one unit of values on the top and the other on the bottom. For example 8cm/5km = x/8km. So you would multiply 8 cm and 8 km and then divide by 5 to get 12.8 cm. For the second question plug in 5m in the numerator and solve for its denominator.
Answer:
None
Step-by-step explanation:
There are actually 2 answers, 3 and -3. Although if you put it in a calculator, it would show "math error" or undefined. That's because the index is even (4) and the radicand is negative (-81)
You have to do the opposite
22-17=5
5x3=15
15+13=28
28/4=7
The answer is 7. You can check this by doing what it says and if it makes 22, it’s correct. (I’ve already checked it) :)
