Let x represent the width of the garden(s). Then the length of the second garden is (3x+3). The area is the product of length and width,
90 = x(3x+3)
30 = x(x+1)
At this point, you can recognize that 5 and 6 are factors of 30 that will satisfy this equation, or you can solve the quadratic
x² +x -30 = 0
(x +6)(x -5) = 0
x = 5 . . . . . . . the negative solution does not apply
The width of the garden is 5 m.
If we put the value of X as 0 we will get the answer zero, So I guess the value of X as 0 will make sense.
Answer:
$3x+$5y=C and the total cost is $ 78
Step-by-step explanation:
the equation first is going to be $3x+$5y=C
x: small balloons
y: large balloons
c: total cost
Now to find the how much the total cost is, you should substitute the variables and then solve the equation.
x: 11
y:9
3(11)+5(9)= 33+45
78
