Answer:
The english class would have half as more so divide the amount that the math class has by 2 and then add i to the english class
Step-by-step explanation:
Number which is not a composite number is given by the equation A = 2
What are Factors of a Number?
Numbers that divide an original number evenly or precisely are known as its factors. A factor is a whole number that can divide a larger number in two equal parts. A factor is a number that divides another number, leaving no remainder
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 equation be represented as A
Now , the value of A is
Let the set of number be in set C = { 2 , 9 , 15 , 21 }
And , composite number is a positive integer that can be formed by multiplying two smaller positive integers
So , the factors of 9 = 1 , 3 , 9
The factors of 15 = 1 , 3 , 5 , 15
The factors of 21 = 1 , 3 , 7 , 21
And , the factors of 2 are 1 and the number 2 itself
Therefore , the value of A = 2
Hence , the number 2 is a composite number

3x-2y=19
Y=x-7
Answer:
x = 5 and y = -2
Step-by-step explanation:
Here you have given what y is equal to, this means you can sub this into the first equation:
3x - 2(x - 7) = 19
Expand the brackets:
-2 * x = -2x
-2 * -7 = 14
3x -2x +14 = 19
Move the +14 over to the other side making it a -14:
3x - 2x = 19 - 14
3x - 2x = 5
3x - 2x = x
So x = 5
Now sub this into the first equation:
3(5) - 2y = 19
15 - 2y = 19
Move the -2y over to the other side making it a +2y, and move the +19 over to the other side making it a -19:
15 - 19 = 2y
-4 = 2y
Divide both sides by two:
y = -2
So x = 5 and y = -2
a. yes; k = -5 b. no c. yes; k = 4/5 d. yes; k = - 4
Answer:
4/5
Step-by-step explanation:
4x-5y=0
subtract 4x on both the sides
4x-4x-5y = 0-4x
-5y = -4x
divide by -5 on both the sides
-5y/-5 = -4x/-5
y =( 4/5 )x
