Answer:
The least common multiple of 6 and 7 is 42
Step-by-step explanation:
One way to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.

the sum of two factors of 48 is nineteen. the larger factor, x, is one more than five times the smaller factor, y. which system of equations can be used to find the numbers
a. x = 19 - y
x = 5y +1
b. x = 19 + y
y = 5x + 1
c. x = y + 19
y = 5x -1
d. x = y - 19
x = 5y +1
The equations that can be used to find the numbers are:
x = 19 - y and x = 5y +1.
Option A is the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
We know that the sum of two factors of 48 is nineteen, so we can write an equation:
x + y = 19
We also know that the larger factor, x, is one more than five times the smaller factor, y, so we can write another equation:
x = 5y + 1
Now we can substitute the second equation into the first equation to eliminate x and solve for y:
(5y + 1) + y = 19
6y + 1 = 19
6y = 18
y = 3
Now we can substitute y = 3 into the second equation to find x:
x = 5y + 1
x = 5(3) + 1
x = 16
So the two factors of 48 that add up to 19 are 3 and 16.
Now let's check which system of equations can be used to find the numbers.
a.
x = 19 - y
x = 5y +1
Substituting the first equation into the second equation, we get:
19 - y = 5y + 1
18 = 6y
y = 3
Substituting y = 3 into the first equation, we get:
x = 19 - y
x = 16
So this system of equations can be used to find the numbers.
b.
x = 19 + y
y = 5x + 1
Substituting the first equation into the second equation, we get:
y = 5(19 + y) + 1
y = 96 + 5y
4y = 96
y = 24
Substituting y = 24 into the first equation, we get:
x = 19 + y
x = 43
So this system of equations does not give us the correct solution.
c.
x = y + 19
y = 5x -1
Substituting the first equation into the second equation, we get:
y = 5(y + 19) - 1
y = 94
Substituting y = 94 into the first equation, we get:
x = y + 19
x = 113
So this system of equations does not give us the correct solution.
d.
x = y - 19
x = 5y +1
Substituting the first equation into the second equation, we get:
y - 19 = 5y + 1
-4y = 20
y = -5
Substituting y = -5 into the first equation, we get:
x = y - 19
x = -24
So this system of equations does not give us the correct solution.
Therefore,
The equations are x = 19 - y and x = 5y +1.

explain why 0.3 x 0.9 doesn't equal 2.7
Answer:
equals 0.27
because of the 0
Step-by-step explanation:
When multiplying decimals 0.3 x 0.9, the correct product is 0.27 not 2.7.
Due to the fact that multiplying decimals requires taking into account the place value of each decimal digit, the product of 0.3 times 0.9 does not equal 2.7.
To reach the result in the hundredth place when multiplying 0.3 by 0.9,
and, multiply the tenth place (0.3) by the tenth place (0.9).
So, 0.3 x 0.9 = 0.27
The product is 0.27, not 2.7.
When the entire numbers 3 and 9 are multiplied, gives number 27.
When the decimal places are ignored, gives 2.7.
Thus, the correct product is 0.27, not 2.7.
