First: let’s get Ben’s current age:
16+4=20
Next let’s get Dunn’s current age:
4/7=20/x
Cross multiply and divide:
x=35
Let’s now add 10 to both ages:
Ben 20+10=30
Dunn 35+10=45
Lastly, let’s find the lowest common multiple of 30 and 45 to determine the ratio:
30:45
Both 30 and 45 can be divided by 15.
30/15=2
45/15=3
Answer:
2:3
The slope of the line that represents the relationship is 0.7692
<h3>slope of a line</h3>
The formula for calculating the slope of a line is expressed as;
Slope = y2-y1/x2-x1
Using the coordinate points (1.3, 1) and (2.6, 2)
Substitute
Slope = 2-1/2.6-1.3
Slope = 1/1.3
Slope = 0.7692
Hence the slope of the line that represents the relationship is 0.7692

Answer:
3y +22
Step-by-step explanation:
y + 6 + 2(y + 8)
Distribute the 2
y+6+2y+16
Combine like terms
3y +22
9x + 3 = 7x +19
2x + 3 = 19
2x = 16
x = 8
So, x (8) is the number of chairs in each row with these setups.
9(8) + 3 = 75
There are 75 chairs total
