Answer:
- 27 is 18 multiplied by 3/2
- 18 is 2/3 of 27
Step-by-step explanation:
The ratio of the two numbers is 18/27 = (2·9)/(3·9) = 2/3.
So, if you're starting with 27 and you want to scale it down to 18, you multiply by the scale factor 2/3.
If you're starting with 18 and you want to scale it up to 27, you use the inverse of the above scale factor. That inverse is 3/2.
Answer:
-11xy
Step-by-step explanation:
-14xy -(-3xy)
multiply the bract first - sign * minus sign is plus sign
-14xy+3xy
since they are like terms u can subtract them.u should subtract them because minus and plus means subtract and we should put minus sign in front of the answer because 14 is the highest number and it's sign is negative .
-11xy
2 angles are Complementary, if the sum of their measures = 90°.
Let the 2 angles be A and B, and let their measures be m(A)=a, m(B)=b.
Let A be the larger angle.
"the larger angle is six more than three times the smaller angle."
can be 'translated' into algebra as: a = 6 + 3b
Also, since A and B are complementary, we have a+b=90°.
substitute a=6+3b in the second equation:
a+b=90°
(6°+3b+b)=90°
4b=90°-6°
b=84°/4=21°
Then, a = 90°-21°=69°
Answer: a= 69°, b=21°
