Find the greatest common factor (GCF)
in this case it would be 9
divide each term by the GCF
36 / 9 = 4
9y / 9 = y
put the two "new" terms in parenthesis and the GCF in front of it
9 (4 + y)
it could also be 9 (y + 4) because of Commutative Property of Addition
Answer:
-2.5625
Step-by-step explanation:
<u>1)[-1/4/5] × [-7/10+0.95] - [-2/1/4] turn that into improper fractions</u>
2 1/4=9/4
which is 1 4/5(-7/10+0.95)9/4
<u>2) 1 4/5(-7/10+0.95)= 0.3125</u>
which is 0.3125-9/4
<u>3)Make into decimal form</u>
9/4 equals 2.25
which is 0.3125-2.25
which all equals -2.5625
500= 120+20x, where x is weeks
Subtract 120 from both sides
380=20x
Divide both sides by 20
19=x
19 weeks*7 days per week= 133 days
Final answer: 133 days
We are talking about a right triangle so the phytagoras equation can be used:
So the hypothinus is equal to approximately 8.49
