<h3>
Answer: B) $1.75</h3>
===================================================
Explanation:
To get the unit cost, we divide the total cost over the number of pounds.
We can do this for any row
- row one: ($17.50)/(10) = $1.75
- row two: ($35.00)/(20) = $1.75
- row three: ($52.50)/(30) = $1.75
- row four: ($70.00)/(40) = $1.75
You don't need to show all four row calculations. You can simply pick one row.
This tells us that each pound costs $1.75
Put another way: the price is $1.75 per pound
The area of a triangle is A=1/2b*h
You have the base (b) and you have the area (A)
So, if you plug in what you know, you get this:
45.5=1/2*10*h
Simplify it:
45.5=5h
Now solve for h
Divide by 5 to get h alone:
9.1=h
Your height is 9.1cm

Answer: B (x = 4)
- x = 2 - 3x + 6 combine like terms
- x = -3x + 8 add 3x
2x = 8 divide by 2
x = 4
Answer:
B
Step-by-step explanation:
1) 38cm
2) 2304cm^2
3) 64cm^2
To find the area you multiply the sides
To find the perimeter you add the sides
