Answer:
Width = 30
Step-by-step explanation:
Area = 18x * 10y = 180xy
Length = 6xy
Width = ?
Since the shape of the office complex is a rectangle,
Area of a rectangle = length × width
180xy = 6xy × width
Width = 180xy / 6xy
Width = 30
Answer:
113
Step-by-step explanation:
Let the number of adult tickets sold =a
Let the number of student tickets sold =s
A total of 259 tickets were sold, therefore:
a+s=259
Adult tickets were sold for $24 each and student tickets were sold for $16 each.
Total Revenue = $5,312
Therefore:
24a+16s=5,312
We solve the two derived equations simultaneously.
From the first equation
a=259-s
Substitute a=259-s into 24a+16s=5,312
24(259-s)+16s=5,312
6216-24s+16s=5,312
-8s=5,312-6216
-8s=-904
Divide both sides by -8
s=113
Therefore, 113 student tickets were sold.

this is because, when dividing an inequality by a negative number, you must flip the inequality sign
-3x < 21
x > -7
Answer:
15 years
Step-by-step explanation:
<u>Given:</u>
- Number of trees = 167
- This year limit = 4 trees
- Yearly limit following years = 6 trees per year
- Target number of trees = 50
<u>Building inequality:</u>
- 167 - 4 - 8x < 50
- 8x > 113
- x > 113/8
- x > 14.125
Adding current year to 14 we get 15 years as answer
After reducing the fraction it becomes equal to 5/12. Let the common element which was cancelled out be x. So we can say the original fraction was

.
The denominator of the fraction is 147 greater than the numerator. We can write it as:
12x = 147 + 5x
12x - 5x = 147
7x = 147
x = 21
So, the numerator of the fraction was 5 x 21 = 105
Denominator of the fraction was 12 x 21 = 252
So our original fraction was
