Answer:
25/10
Step-by-step explanation:
Make the fractions improper by multiplying the whole number by the denominator and then adding the numerator (if this makes sense).
This makes 5x10=50+3=53/10
Do the same for the second fraction. 2x5=10+4=14/5
Then make the denominators the same, and in this case all you need to do is multiply both sides of 14/5 by 2, so that makes 28/10.
Now, just take it away.
53/10-28/10=25/10, which can be then simplified into 2 1/2 or 5/2.
I'm gonna say A. It makes the most sense to me.
Answer:x=90° y=58° z=32°
Step-by-step explanation:
x=90
y=180-(90+32) sum of angles in a triangle is 180
y=58
y+90+z=180 they are supplementary
58+90+z=180
148+z=180
z=180-148
z=32
Answer:
Number of bags required = 486
Total cost to fill the window box = $2415.42.
Step-by-step explanation:
Volume of the rectangular prism = l × b × h
= 12 × 9 × 9 cubic feet
Volume of 1 bag of soil = 2 cubic feet
Number of bags required = 
= 486
Cost of one bag = $4.97
Cost of 486 bags = 486 × 4.97 = 2415.42
Hence, total cost of filling the window box = 2415.42.
