Answer:
Step-by-step explanation:
Let x and y represent the cost of a cupcake and cookie respectively.
Given that;
Five cupcakes and two cookies cost $19.75.
Two cupcakes and four cookies cost $17.50.
Let's solve the simultaneous equation by elimination;
Multiply equation 1 by 2;
Subtract equation 2 from equation 3;
divide both sides by 8
Since we have the value of x, let substitute into equation 1 to get y;
therefore , the cost of cupcakes and cookies are;

Answer:
x = 12
y = 6√3
Step-by-step explanation:
✅Apply the intersecting secant theorem to find x. Thus:
6(6 + x) = 7(7 + 8³/7)
Convert the mixed fraction to improper fraction
6(6 + x) = 7(7 + 59/7)
36 + 6x = 49 + 59
36 + 6x = 108
6x = 108 - 36
6x = 72
Divide both sides by 6
x = 72/6
x = 12
✅Apply the tangent-secant theorem to find y. Thus:
y² = 6(6 + x)
Plug in the value of x
y² = 6(6 + 12)
y² = 6(18)
y² = 108
y = √108
y = 6√3

Answer:
6x
Step-by-step explanation:
The area is given by the formula ...
A = LW
Fill in the given values and solve for width.
24x^3 = (4x^2)W
W = (24x^3)/(4x^2) = 6x
The width of the rectangle is 6x.
