According to the given formula, the value of a is:

60

If b=30 then 1/2a+2/3b=50

First, replace the 30 in b.

1/2a+2/3(30)=50

According to the order of operations, we must first multiply 2/3 by 30. yes:

2/3 times 30 is equal to 20.

2/3 times 30/1. 3 is 10 times 30, so 2 times 10 = 20. Now it looks like this:

1/2a+20=50

20 and 50 are similar terms, so I'll put those two together. Move the positive 20 to the other side where the 50 is. 20 has moved to the other side, so it changes sign and becomes negative.

yes:

1/2a=50-20

50-20 = 30

1/2a=30

Multiply each side by 2, because only 2 makes the variable 1a.

1/2a × 2 = 1a

30 times 2 = 60, so:

1a=60, which is also a=60. So a perfect simplification is a= 60

If the rate of walking is 1. 4 meters per second, then 357.14 sec would take you to walk 500 meters.

We can calculate speed, distance or time using the formula s = d/t, distance equals speed times time. The Speed Distance Time formula can solve for the unknown sdt value given two known values.

Time can be entered or solved in units of seconds (s), minutes (min), hours (hr), or hours and minutes and seconds (hh: mm: ss).

We have,

The rate of walking is 1. 4 meters per second.

The distance to cover is 500 meters.

Now, we know the formula

OC (x+1)(x-8)(4)=56 indicates that the volume of the box is 56 in³ because it takes into account the length of the sides after the four corners were cut off, and the height of the box which is 4 in. The equation can be written as (length of sides)(width of sides)(height) = volume.

A volume is a three-dimensional space that contains a specific amount of material, which is commonly measured in liters, cubic meters, or gallons. It is frequently used to calculate the capacity of containers like tanks, bottles, and barrels. Volume may also refer to the quantity of space occupied by an item, such as the volume of a room or the volume of a sphere.

In the given question, OC is the correct answer: (x+1)(x-8)(4)=56. This equation reveals that the volume of the box is 56 [tex]in^{3}[/tex] because it considers the length of the sides after the four corners were taken off, which are (x+1) and (x-8), as well as the height of the box, which is 4 in.

Answer: An arithmetic sequence is a sequence of numbers in which the difference between any two consecutive terms is constant. We can call this constant difference "d".

In this sequence, we can see that the difference between consecutive terms is -6x - 5.

The 9th term of an arithmetic sequence can be found by using the formula:

a_n = a_1 + (n-1)d

Where a_n is the nth term of the sequence, a_1 is the first term of the sequence and d is the common difference.

Given the sequence -5x + 2, -11x - 3, -17x -8, ...

The 9th term is:

-5x + 2 + (9-1) (-6x-5) = -5x + 2 - 48x - 40 = -53x -38

Therefore the 9th term of the arithmetic sequence is -53x -38.

The packages of paintbrushes, p, that Mr. Grant needs to buy in order to have at least 55 paintbrushes will be at least 5 packages.

Inequalities are simply created through the connection of two expressions. In this case, it should be noted that the expressions in an inequality are not always equal. Inequalities implies that the expressions are not equal. Here, they are denoted by the symbols ≥ < > ≤.

In this case, Grant has 25 paintbrushes already and will buy more paintbrushes in packages of 6.

The inequality to illustrate this will be:

Step-by-step explanation:

In this problem, we use the variable c to represent the independent quantity.  This means that the domain is all possible values for c. Since the store only has 8 cases of water, the domain cannot be any number larger than 8. Since the store only sells complete cases, not partial cases, of water, the domain cannot be a fraction or decimal number. This means that the practical domain, or domain that makes sense for the problem situation, is {1, 2, 3, 4, 5, 6, 7, 8}.

Answer: The perimeter of a rectangle is the sum of the lengths of all four sides. If one of the sides is 6(1/2x + 5), then we can find the perimeter by multiplying that by 2.

Perimeter = 2*6(1/2x + 5)

Perimeter = 12(1/2x + 5)

To simplify the expression, we can distribute the 12:

Perimeter = 121/2x + 125

Perimeter = 6x + 60

So the perimeter of 6(1/2x + 5) is 6x + 60.

Jessica gets more rocks to skip across the surface of the pond than Henry.

To determine who gets more rocks to skip across the surface of the pond, we will take the ratio of rocks that skip to rocks that are thrown for each person.

For Henry, the ratio is 5 rocks that skip to 9 rocks thrown i.e 5/9.

For Jessica, the ratio is 7 rocks that skip to 12 rocks thrown i.e 7/12.

Now to compare the ratios, we need to convert them into like fractions. We will do this by making the denominations of both the fractions same.

We will multiply the numerator and denominator of Henry's ratio by 12 to get -

5/9 x 12/12 = 60/108

Also, we will multiply the numerator and denominator of Jessica's ratio by 9 to get -

7/12 x 9/9 = 63/108

Comparing the numerators we get 60<63.

This implies that 60/108 < 63/108.

Therefore, Jessica gets more rocks to skip across the surface of the pond.
