Answer:
1)0.6x=54 2)90
Step-by-step explanation:
1) 60% is the same as 0.6 and finding 60% is the same as as doing 0.6 times whatever the number is and here we don't know the number so it would be x. so 0.6 times x or 0.6x=54. You could also just write 60% of x=54
2) You would have to do the opposite of finding 60%.
So you would do 54/6=9 and 9*10=90. this is because to find 60% you have to do divide by 10 and times by 6. So you do the opposite. you can check your answer by doing 60% of 90. So 90/10= 9 and 9*6=54. Therefore his fundraising goal is $90

Answer:
2/3
Step-by-step explanation:
The slope is rise over run so all you have to do is make a triangle from the two points, count how many go up, which is 2, and how many go to the side, which is 3. The rise (2) goes on the top of the fraction, the run (3) goes on the bottom and then that's your answer.

what is the value of k ?
Answer:
27-degrees
Step-by-step explanation:
these are vertical angles which are equal to each other *congruent
39 + k = 66 --> *subtract 39 from both sides*
k = 27
Answer:
27°
Step-by-step explanation:
Remember the angle opposite of another angle in two straight lines are equal
So 66=39+k
Then put k by itself by subtracting 39 from both sides
66-39=k
k=27°

a florist orders sunflowers every 6 days, starting from the sixth day of the year, and daisies every 4 days starting from the fourth day of the year. when is the first THREE TIMES she will order the flowers on the same day?
Answer: 12th day
Step-by-step explanation:
Given , A florist orders sunflowers every 6 days and daisies every 4 days.
When it started from same day, then the next day she orders both kinds of flowers on the same day will be LCM (6,4), where LCM = Least Common Multiple.
Prime factorization:
6 = 2 x 3
4 = 2 x 2
LCM(6,4) = 2 x 2 x 3 = 12
Hence, she will order both kinds of flowers every 12 days.
