Fetures are x and y
x+y=12
23.99x+120.84y=675.28
x+y=12
multiply by -23.99 and add to other equation
-23.99x-23.99y=-287.88
<u>23.99x+120.84y=675.28 +</u>
0x+96.85y=387.4
96.85y=387.4
divde both sides by 96.85
y=4
sub back
x+y=12
x+4=12
minus 4
x=8
8 of the features costing $23.99
4 of the features costing $120.84

First, divide the shape into two shapes: the trapezoid on the very top and the large rectangle that makes up most of the bottom. Then, find the area of each, and add them together for the total area.
<u>Trapezoid:</u>
A=0.5(b1+b2)h
A=0.5(7+14)5
A=0.5(21)5
A=52.5
<u>Rectangle:</u>
A=lw
A=12(14)
A=168
52.5+168=220.5
The area is 220.5 square feet.
Hope this helps!!
Answer:
an 8 ounce package would be the lower cost per ounce
Step-by-step explanation:
one pound represents 16 ounces so 1/4 of 16 ounces would be 4 ounces
so it cost $8.25 for 4 ounces of almonds and would cost $16.50 for 8 ounces of almonds instead of the other package that is offering 8 ounces of almonds for $0.50 cheaper
hope this helps and makes sense <3
Y<-18 or y>18 would work i think
1 yard is 3 feet
4 yards is 12 feet
so 6' to 12' is 6/12
<span>or 1/2</span>
