Answer:
$9.70
Step-by-step explanation:
Use PEMDAS:
Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
Problem:
C(x) = 0.06x + 8.50
Substitute x for 20:
C(20) = 0.06(20) + 8.50
Multiply 0.06 and 20:
C(20) = 1.2 + 8.50
Add 1.2 and 8.50:
C(20) = $9.70
The total cost for an order of 20 copies is $9.70
Answer:
1. 3cm
2. 6m
Step-by-step explanation:
If all angles are right angles, it means that both lengths on the right side add up to the length on the left side.
For the first one, the length on the left is 7cm, and there are two lengths on the right: 4cm and an unknown we can call 'x'.
We know that both of the right lengths add to the left length so we can represent this as so:
4+x=7
To solve for x we can minus 4 from both sides:
x+4-4 = 7-4
x = 7 -4
x = 3cm
We can solve the second one in a similar fashion:
x + 6 = 12
x + 6 - 6 = 12 - 6
x = 12 - 6
x = 6m
Hope this helped!
Answer:
542 miles
Step-by-step explanation:
St. Paul to Madison, Wisconsin = 260 miles
St Paul to Bismarck, North Dakota = 437 miles
4 round trips to Madison = 4 * 2 * 260 = 2080 miles
3 round trips to Bismarck = 3 * 2 * 437 = 2622 miles
Difference in miles traveled :
2622 miles - 2080 miles = 542 miles
