Answer:

Step-by-step explanation:

we have 105 marbles

number of blue marbles= x

green marbles= x+25

x+x+25=105

2x=105-25

2x=80

x=40 blue marbles

The perimeter of a rectangular movie screen at a local cinema is 148 feet. If the length of the screen is 30 feet longer than th
Rudiy27

The perimeter of a rectangle = 2(l + w)

l = length

w = width

In this problem,

w = x

l = x + 30

the perimeter = 148

Let's plug our values into the perimeter formula above.

148ft = 2(x + x + 30ft)

Combine like terms.

148ft = 2(2x + 30ft)

Distribute the 2

148ft = 4x + 60

Subtract 60 from both sides

88ft = 4x

Divide both sides by 4

22ft = x

The width = x = 22ft

The length = x + 30 = 22 + 30 = 52ft

Answer:

Derrick mistakenly combined the numbers adding it together but the numbers are not the same value to be combined. You cannot add yards and ft together.

Width = 55ft

Area = 4950 sq ft

Cost = $9900

Step-by-step explanation:

Derrick mistakenly combined the numbers adding it together but the numbers are not the same value to be combined. You cannot add yards and ft together.

You have to convert the yards to ft to add it to the other ft.

1 Yard = 3 ft

So the width is  18 yards 1 ft = 54ft + 1ft = 55ft

To calculate the  area is L x W

The length is 30 yards. Convert that to ft = 90ft

So 90 x 55 = 4950 sq ft

At $2 per sq ft, you multiply the 4950 sq ft by $2

2 x 4950 = $9900

Find the values of x for which the combined function h(x) = is undefined if f(x) = 5x + 1 and g(x) = x2 - 9.
Rama09 [41]
We need to know the definition of the "combined function" h(x).  I'm going to guess--by looking at answers--that the function is h(x)=\frac{f(x)}{g(x)} making it

h(x)=\frac{5x+1}{x^2-9}

This function is undefined wherever the denominator is equal to 0 (division by zero is undefined).  Factor the denominator.

h(x)=\frac{5x+1}{(x+3)(x-3)}

The two values of x that make the denominator 0 are 3 and -3, otherwise written x=\pm 3.
