Logan has two aquariums. One aquarium contains 2.5 cubic feet of water and the other contains 1.7 cubic feet of water. The water in the larger aquarium weighs 49.92 pounds more than the water in the smaller aquarium. Complete the equation with a variable on both sides to represent the situation. Use x to represent the weight of 1 cubic foot of water. Then find the weight of 1 cubic foot of water.

Answer:

C

Step-by-step explanation:

Since the ratio is 5:3, that means if Adam has 5 songs, his mother has 3. That means we can eliminate the last table. We can also eliminate the first table since it isn't possible. Let's look at B, 5x6 is 30, but 3x6 is not 18, so that is incorrect. This means the table is C. Let's make sure, though. The first row is correct. 5x2 is 10 and 3x2 is 6, so the second row is correct. 5x5 is 25 and 3x5 is 15, so the entire table is correct.

Answer:

4(x+8)

Step-by-step explanation:

5.5 is the constant numerical value of y ÷ 3(4 - 2) + 5.5

An expression is combination of variables, numbers and operators.

Given,

y ÷ 3(4 - 2) + 5.5

y divided by 3 times of four minus two plus five point five.

y/3(4-2)+5.5

3(4-2) we can use distributive property

y/12-6+5.5

Now subtract 12 minus 6 we get six

y/6+5.5

Constant term whose value does not chang.

Hence, 5.5 is the constant numerical value of y ÷ 3(4 - 2) + 5.5

Step-by-step explanation:

=================================================

Let,

x = number of pounds of chocolate

y = cost of buying x pounds of chocolate

If you buy x = 2 pounds, then you spend y = 9.98 dollars.

So k = y/x = 9.98/2 = 4.99 is the cost per pound. This is known as the unit price or unit cost. It's the cost of one pound of chocolate.

Now if you buy x = 5 pounds, then you'll be charged a total of y = 24.95

So, k = y/x = 24.95/5 = 4.99

We get the same constant of proportionality here, and therefore, this is a direct proportional relationship. Each time x goes up by 1, y goes up by 4.99; in other words, each time you buy 1 extra pound of chocolate, you pay $4.99 more. This is to be expected whenever you're at the grocery store as long as you ignore things like coupons or bulk discounts or things of that nature.

The equation of this line is y = 4.99x

This shows the slope is 4.99 and the y intercept is 0.

------------------

An alternative approach:

Again we define x and y as stated above. We see that the two points are (2,9.98) and (5,24.95)

Computing the slope gets us

m = (y2-y1)/(x2-x1)

m = (24.95-9.98)/(5-2)

m = 14.97/3

m = 4.99

So this matches what we got earlier.

Now turn to y = mx+b. Plug in that value of m along with (x,y) = (2,9.98)

Doing so gets us 9.98 = 4.99*2+b

Let's solve for b

9.98 = 4.99*2+b

9.98 = 9.98+b

0 = b

b = 0

I subtracted 9.98 from both sides to isolate b. The fact we get the y intercept is 0 helps show that we have a direct proportion. All direct proportion linear equations go through the origin (0,0). This is to reflect that buying 0 pounds of chocolate means you pay 0 dollars.

We get the same result as the previous section.

Answer:

The fencing will cost about $740.16.

Step-by-step explanation:

Find how much fencing is needed around the garden by finding the perimeter of the semicircular garden. To find the perimeter of a semicircle, add half of the circumference of the circle to the diameter of the circle.

P =   1 / 2 πd + d Use the circumference formula and divide it by 2 because the garden is a semicircle. Add the diameter to take into account all sides of the semicircle.

P ≈   3.14(36) /2  + 36 Substitute for the diameter and π.

P ≈ 92.52 Simplify.

The perimeter of the semicircular garden is about 92.52 feet, therefore the fence will be 92.52 feet long.

Find how much the fencing will cost altogether. Multiply the length of the fence by the cost per linear foot of the fencing.

92.52 × 8.00 = 740.16

Step-by-step explanation:

6x + 18 = 3(2x + 7) - 3

open the brackets by using 3 to multiply the bracket behind it

6x + 18 = 6x + 21

collect like terms. when + crosses = sign it changes to -

6x - 6x = 21 - 18 - 3

0 = 21 - 21

0

4(0.5a + 3) = 2a + 12

multiply contents of the bracket with 4

2a + 12 = 2a + 12

collect like terms. when + crosses = sign it changes to -

2a - 2a = 12 - 12

0

x + 4 - 6x = 6 - 5x - 2

collect like terms. when + crosses = sign it changes to -

x + 5x - x = 6 - 4 - 2

6x - 6x = 6 - 6

Answer:

The correct answer's B, give brainly if this helped :)

Step-by-step explanation:

Answer: 1. x=9, 2. x= -6/5 or x = -1.2

------------------

We create the equation

2x+3=3x-6

add 6 to each side

2x+9=3x

Subtract 2x from each side

9=x

The value of x is 9h

We'll use substitution.

In the first equation y equals x-4 so we can replace the y in the second equation with that

x-4=6x-10 Now solve

add 4 to each side

x=6x-6

subtract 6x

-5x=6

divide each side by -5

[tex]x = - \frac{6}{5} [/tex]

Answer:

Step-by-step explanation:

Well you see the y is always 12 so it just stays like that. Then you see the x goes up by 4 every time so its 4/12. Or simplify it.
