is the same thing as
and
Therefore, the first option is correct.
Answer:
x=5, y=-2. (5, -2).
Step-by-step explanation:
2x+3y=4
3x+4y=7
----------------
3(2x+3y)=3(4)
-2(3x+4y)=-2(7)
----------------------
6x+9y=12
-6x-8y=-14
-----------------
y=-2
2x+3(-2)=4
2x-6=4
2x=4+6
2x=10
x=10/2
x=5
Since the height is different on both ends, we can assume that the wall is a trapezoid. Knowing that, we can replace the measures we know in the formula and our onky variable is the length of the wall - we only need to isolate it.
A= ((b+B)h)/2
26.4=((2+2.4)h)/2
52.8=4.4h
h=12
Answer:
Total area: 9/5 square cm, or in decimal form 1.8 square cm
Step-by-step explanation:
Notice that each sticker is 1/2 cm by 3/5 cm, therefore they area is 1/2 times 3/5 = 3/10 square cm.
since she uses 6 of them, we need to multiply the area of each by 6 in order to get the total area:
6 times 3/10 = 18/10 square cm = 9/5 square cm or in decimal form 1.8 square cm
To the left or the right bro?
