Step-by-step explanation:
area = length x width
area = 1,792 sq cm
length = 56 sq cm
width = ?
equation = 1,792-56= 1,736
Answer:
1,736 sq cm
Eliminate x's
multiply 2nd equation by -2 ad add to first
2x+3y=9
<u>-2x-10y=-16 +</u>
0x-7y=-7
-7y=-7
divide by -7
y=1
sub back
2x+3y=9
2x+3(1)=9
2x+3=9
minus 3
2x=6
divide 2
x=3
x=3
y=1
(x,y)
(3,1)
D
Answer:
18.50 times 3 equals 55.5, the answer is 55.50
X= -10.5+9.5
X=1
