Cross multiply
12x=900 Divide both sides by 12.
x=75 hammers to begin with.
it is true because al triangles angles MUST add up to 180

Step-by-step explanation:
Answer:
$50
Step-by-step explanation:
If the original price was $10 more than the sale price, so we know that in this case, 20% = $10. Because 20% is equivlalent to
, multiply $10 by 5 to get the answer of $50.
-2 | 8-x| - 6 = -12...add 6 to both sides
-2 |8-x| = -12 + 6
-2 |8-x| = - 6...divide both sides by -2
|8-x| = -6/-2
|8-x| = 3
8 - x = -3 -(8 - x) = -3
-x = -3-8 -8 + x = -3
-x = -11 x = -3 + 8
x = 11 x = 5
