Answer:
12
Step-by-step explanation:
You need the greatest common factor of 168 and 60.
168 = 2^3 * 3 * 7
60 = 2^2 * 3 * 5
For the GCF, you need common factors with the lower exponent.
Between 2^3 and 2^2, choose 2^2.
Then you have 3 as a common factor.
5 and seven are not common.
GCF = 2^2 * 3 = 12
Answer: 12
Answer:
- 5
Step-by-step explanation:
Note that - (- 12) = + 12
Thus
- 17 - (- 12) = - 17 + 12 = - 5
It looks like Tom subtracted 12 from - 17, that is - 17 - 12 = - 29
Answer:
d>67
Step-by-step explanation:
Let's solve your inequality step-by-step.
−50−(−9d+7)>−d+10+9d
Step 1: Simplify both sides of the inequality.
9d−57>8d+10
Step 2: Subtract 8d from both sides.
9d−57−8d>8d+10−8d
d−57>10
Step 3: Add 57 to both sides.
d−57+57>10+57
d>67
