Answer:
Cost of one candy = 80 L.L.
Step-by-step explanation:
Let "x" represent cost of a candy
Cost of 12 candies = 12x
Cost of a chocolate bar = 1,250 L.L.
Total cost = 2,210 L.L.
The following equation represents the scenario given:
1,250 + 12x = 2,210
Solve for x (cost of a candy)
1,250 + 12x - 1,250 = 2,210 - 1,250 (subtraction property of equality)
12x = 960
Divide both sides by 12
12x/12 = 960/12 (division property of equality)
x = 80
Cost of one candy = x = 80 L.L.
Answer:
Step-by-step explanation:
Given that:
the perimeter of the fencing (rectangle) = 200
Let recall that the area equation of a rectangle = L × w
The perimeter now = 2(L + w)
The perimeter = 2L + 2w
∴
200 = 2L +2w
Dividing both sides by 2
100 = L + w
Making Length L the subject; we have:
- L = -100 + w
L = 100 - w
Thus;
A(w) = (100 - w) w
and the domain of the function is (0,100)
The slop is -1 and the y-intercept is (0,7) so then go on the graph and plot a point on the y- axis line at 7. Then go right 7 units and down 7 units and that should be it :)
