Restaurant 1 : y = 7k + 39
restaurant 2 : y = 2k + 44
7k + 39 = 2k + 44
7k - 2k = 44 - 39
5k = 5
k = 5/5
k = 1
y = 2k + 44
y = 2(1) + 44
y = 2 + 44
y = 46
Dinner would cost $ 46 at either restaurant if Lina's lobster weighed 1 kilogram.
I hope this helps you
x= -3
y=3. (-3)+2
y= -9+2
y = -7
Answer:
Step-by-step explanation:
If the sector wasn't there, the area would be that of a circle. The formula for a circle = pi * r^2
But the sector is there and so you have to account for it.
Area sector = (60/360) * pi * 11^2
Area sector = 1/6 * pi * 121
1/6 of 121 = 20.17
Area of sector = 20.17 pi square cm

Step-by-step explanation:
This is a great question!
If x were the length of this rectangle, then we could conclude the following,
2( 38 ) + 2( x ) > 692,
As you can see there is a greater than sign present, as the perimeter is at least 692 centimeters. In this case the perimeter is given to be at least 692 centimeters, but can also be calculated through double the width and double the length together. And of course we are given the width to be 38 cm -
2( 38 ) + 2x > 692,
76 + 2x > 692,
2x > 616,
x > 308
<u><em>Solution = Length should be at least 308 cm</em></u>
