Answer:
chairs: $1.75, tables: $6.50
Step-by-step explanation:
x is tables, y is chairs.
3x +2y=23
5x+6y=43
then:
9x+6y=69 ( multiply all by 3)
-5x-6x=-43 (multiply by -1)
Now add
4x=26
x=6.5
plug x back in to find y
3(6.5)+2y+=23
2y=3.5
y=1.75
Answer:
36 m
Step-by-step explanation:
Just plug in the 30° into that equation.
<span>A(30°) = 16sin(30°)(cos(30°) + 1) </span>
<span> = 16(1/2)(1 + √3/2) </span>
<span> = Approx 14.9 in² </span>
<span>So A is the answer. </span>
7y + 8 + 6 (x + 5 )
7y + 8 + 6x + 30
7y + 38 + 6x. ~~~~
