The solution is $ 96

The cost of 40 pints of ice cream is given by the equation A = $ 96

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the cost of 40 pints of ice cream be A

Now , the equation will be

The cost of 6 pints of ice cream = $ 14.40

So , the cost of 1 pint of ice cream = cost of 6 pints of ice cream / 6

Substituting the values in the equation , we get

The cost of 1 pint of ice cream = 14.40 / 6

The cost of 1 pint of ice cream = $ 2.40

Now ,

The cost of 40 pints of ice cream A = 40 x cost of 1 pint of ice cream

Substituting the values in the equation , we get

The cost of 40 pints of ice cream A = 40 x 2.40

The cost of 40 pints of ice cream A = $ 96

Therefore , the value of A is $ 96

Hence , the cost is $ 96

Answer: 11 magazines

Step-by-step explanation:

1)     20/5 = $4 per magazine

2)     44/4 = 11 magazines

Answer:

10 magazines

Step-by-step explanation:

5 magazines cost $20.00

You have $44.00

If 5 magazines cost $20.00

Then 10 magazines would cost $40.00

Since the maximum amount of money you can spend is $44.00, you can only buy 10 magazines for $40.00 and be left with $4.00.

Step-by-step explanation:

Answer: n = 152 m

Step-by-step explanation:

write a proportion to find n.

46/n = 92/204

n = 102 m

The length of the lake shown in the provided image using similar triangles and a proportion is 102 meters.

In the two similar triangle, the ratio of two sides of one triangle is equal to the ratio of corresponding sides of the other triangle.

In the figure shown,

The total length of the base of the larger triangle is,

[tex]112+92=204\rm\; m[/tex]

The height of this triangle is n meters, which is equal to the length of lack. Thus, by the similar triangle proportion property,

[tex]\dfrac{n}{204}=\dfrac{46}{92}\\n=\dfrac{46\times204}{92}\\n=120\rm\; meters[/tex]

Thus, the length of the lake shown in the provided image using similar triangles and a proportion is 102 meters.

Half the perimeter is the length + the width.

Let the width = x

The length is x + 4. ( 4 feet more than the width)

Now you have x + x + 4 = 20

Combine like terms:

2x + 4 = 20

Subtract 4 from both sides:

2x = 16

Divide both sides by 2:

X = 8

The width is 8 feet

The length is 8 + 4 = 12 feet

Answer: 3

Step-by-step explanation:

f(x)= -x + 4

Therefore f(-1)= -(-1)+4= 1+4= 5

h(x)= (3/2)x - 1

Therefore h(2)= (3/2)(2) -1= 3-1= 2

f(-1) - h(2)= 5 - 2= 3

Answer:

depends on the other side, so... maybe

Step-by-step explanation:

If you have a rectangle and you know one side is 5.25, then if the perpendicular side looks about the same length or longer, then the area of the rectangle is at least 25.

Imagine you have a rectangle with a known base of 5.25, then if the rectangle is at least as tall as it is wide, then the area is over 25.  If the rectangle is very close to a square then the area should be near 25, and if the rectangle is visually shorter than it is wide then the area is less than 25
