Answer: 7
Step-by-step explanation:
Answer:
7 is the GCF of 21 and 28
Step-by-step explanation:
The GCF of 21 and 28 is 7. To calculate the greatest common factor (GCF) of 21 and 28, we need to factor each number (factors of 21 = 1, 3, 7, 21; factors of 28 = 1, 2, 4, 7, 14, 28) and choose the greatest factor that exactly divides both 21 and 28, i.e., 7.
-268=-6(-6-6k)+2k
k= ???
Answer:
k = - 8
Step-by-step explanation:
- 268 = - 6(- 6 - 6k) + 2k ← distribute parenthesis by - 6
- 268 = 36 + 36 k + 2k ( subtract 36 from both sides )
- 304 = 38k ( divide both sides by 38 )
- 8 = k

Which pitcher has the lowest number of runs allowed per inning?
The pitcher that has the lowest number of runs allowed per inning is Randy.
Which pitcher has the lowest number of runs per inning?In order to determine the pitcher that has the lowest number of runs per innings, divide the number of runs of each player by the number of innings of that player.
Division is the mathematical operation that is used to calculate the quotient of two or more numbers. It entails grouping a number into equal parts using another number.
Number of runs per innings = number of runs / number of innings
Number of runs per innings for Randy : (2 / 3) = 0.667
Number of runs per innings for Felix : (4 / 5) = 0.80
Number of runs per innings for Johan: (5 / 7) = 0.714
Here is the complete question:
A baseball team has three different pitchers. Randy pitched 3 innings and allowed 2 runs, Felix pitched 5 innings and allowed 4 runs, and Johan pitched 7 innings and allowed 5 runs.

The system of equations has no solutions, meaning that the two lines never intersect, as shown by the image at the end of the answer.
What is a system of equations?A system of equations is a set of equations in the context of a problem, and these equations are solved to find the numeric value of each variable of the problem.
When the system involves linear equations, such as is the case in this problem, the solution is given by the intersection point between these two lines.
In this problem, the equations are given as follows:
2x - 4y = 4.x - 2y = 8.From the second equation, it is found that:
x = 8 + 2y.
Replacing on the first equation, the solution for y can be obtained as follows:
2(8 + 2y) - 4y = 4
16 + 4y - 4y = 4
0y = -12
Which is a contradiction, hence the system has no solutions and the two lines do not intersect.

The integer in the set S:{−24, 2, 20, 35} that will make the inequality five-sixths m minus five is less than one-half m plus 3 false is 35
What is inequality?Inequalities are created through the connection of two expressions. It should be noted that the expressions in inequality aren't always equal. Inequalities imply that the expressions are not equal. They are denoted by the symbols ≥ < > ≤.
In this case, based on the information we will replace m with 35. This will be illustrated thus:
= 5/6(35 - 5) < 1/2(35 + 3)
= 5/6(30) < 1/2(38)

Calculate capital if assets are £451,100, liabilities are £20,500, income is £351,200 and expenses are £270,600.
The capital is £430,600.
Define capital.
The money that a company has on hand to support both its current operations and potential expansion is known as capital. One source of funding for it is the earnings from its operations. When calculating a company's capital worth, all of the company's physical assets and financial assets would be included (minus its liabilities).
The capital account—also referred to as the capital and financial account—records the net flow of investment transactions into an economy and is used in macroeconomics and international finance.
Solution Explained:
Given, Assets = £451,100 and liabilities = £20,500
Capital = Assets - Liabilities
= 451100 - 20500
= £430,600

6) Tomás está haciendo compras en el supermercado. Primero eligió

gramos más debe comprar si quiere llegar a 5 kg?
With the help of unitary method it can be found out that Tomás has to buy more 3650 grams of oranges if he wants to reach 5 kg.
It is given to us that -
Tomás first chose a tray with oranges whose label says 1,350 gram
We have to find out more grams of oranges that he should buy if he wants to reach 5 kilogram.
We know that
1 kilogram = 1000 grams
=> 1000 grams = 1 kilogram ----- (1)
By unitary method, we can find out the number of kilograms equivalent to 1350 grams of oranges.
From equation (1), we have
1000 grams = 1 kilogram
=> 1350 grams = (1/1000) * 1350
=> 1350 grams = 1.35 kilograms ----- (2)
Now, from equation (2), we can see that Tomás first chose 1,350 grams of oranges which is equal to 1.35 kilograms of oranges.
This implies that the more kilograms of oranges that Tomás has to buy to reach 5 kilograms is given by -
(5 - 1.35) kilograms
= 3.65 kilograms
From equation (1), we have
1 kilogram = 1000 grams
=> 3.65 kilograms = 3.65 * 1000 grams
=> 3.65 kilograms = 3650 grams.
Thus, by solving through unitary method we find out that Tomás has to buy more 3650 grams of oranges if he wants to reach 5 kg.
