Draw a number line with 10 positives and 10 negatives. Count from 0 to 8. Now, from 8, count back 12 spots. From that spot, go back to 0, which is their original position. The number you counted there is your answer.
Answer:
42.7 cm sq.
Step-by-step explanation:
small/large = 16 / 122
16/122 = S / 56
S = 56 * (16/122) = 7.34...
however not in the choice
ah ha..
You meant : 12.2 sq. cm : 16 sq. cm = small / large
so 12.2 / 16 = S / 56 cm
S = 42.7 sq. cm
Answer:
Step 2
18 over 8 to a decimal is 2.25
Step-by-step explanation:
Step 1, 20, subtract 16 labeled as
Step 2, 40 labeled as
Step 3, subtract 40, and 0 labeled as Step 4.
Divisor = 8
Divided = 18
Quotient = 2.25
2.25
8 √18
- 16
2 0
- 16
4 0
- 40
0
The first error is at step 2
18 over 8 to a decimal is 2.25
