A 42-inch board is to be cut into three pieces so that the second piece is twice as long as the first piece and the third piece is 3 times as long as the first piece. If x represents the length of the first piece, find the lengths of all three pieces.
Answer:
The first piece has a length of 7 inches, the second has a length of 14 inches and the third has a length of 21 inches.
Step-by-step explanation:
x represents the length of the first piece.
Hence, the second piece has a length of 2x and the third piece has a length of 3x.
Hence, x + 2x + 3x = 42 inches.
x + 2x + 3x = 42 inches
6x = 42 inches
x = 7 inches
Hence, the first piece has a length of 7 inches, the second has a length of 14 inches and the third has a length of 21 inches.
Hope this helped!

Solve the rational equation x over 4 equals x squared over quantity 3 times x plus 3 and check for extraneous solutions.
x = 1; x = 0 is an extraneous solution
x = 0; x = −1 is an extraneous solution
x = 0 and x = 1
x = 0 and x = −1
Answer:
x is -9 is an extraneous solution
Step-by-step explanation:
Given the expression
x/4 = x²/3(x+3)
We are to find the value of x
Cross multiply
3x(x+3) = 4x²
3x²+9x = 4x²
3x²-4x² = 9x
-x² = 9x
-x = 9
x = -9
Hence the value of x is -9 is an extraneous solution

Step-by-step explanation:
6(x + 4) - 8 = 6x - 16
6x + 24 - 8 = 6x - 16
6x - 16 = 6x - 16
6x = 6x
x = x
RHS = LHS
Therefore, x can be any real number.

Twice a number is 42 less then five times a number. What is the number? Define a variable, write an equation, and then solve.
Answer:
Given - Twice a no. is 42 less than 5 times a no.
To find - The no.
Solution -
Let the no. be XAccording to the question the equation made is -
2x = 5x - 42
2x - 5x = (-42)
(-3x) = (-42)
x= (-42)/(-3)
x = 14
The no. is 14

Answer:
The answer is x= 50 and y=50.
Step-by-step explanation:
So a straight line is always equal to 180 degrees. So, to find the length of the inner angle, subtract 100 from 180= 80. Now that you've gotten the value of that angle, you'll have to find x and y. All angles of a triangle add up to 180 degrees. 180-80= 100. The small dash on both of those lines means they are equal. Do 100/2 = 50. Hope this helps!

Barry has 7 coins, all of which are quarters and nickels. In all, they're worth $1.35. How many of each kind of coin does Barry have?
Answer:
5 quarters
2 nickels
Step-by-step explanation:
Answer:
5 quarters and 2 nickels.
Step-by-step explanation:
One quarter is equal to 25. 25x5=125. So, it would be 5 quarters because you wouldn't be able to go any farther without going over. One nickel is 5 and if you have 2 nickels you get 10. 10+125=135. So, there will be 2 nickels and 5 quarters.

5 3/7 - 2 1/5
Answer:
Step-by-step explanation:
5 3/7= 38/7 (move the wholes into the fraction)
2 1/5=11/5
38/7- 11/5 we need the common denominator=35
190/35 -77/35= 113/35

In a 2^4 factorial design, the number of degrees of freedom for the model, assuming the complete factorial model, is:_____
a. 7
b. 5
c. 6
d. 11
e. 12
f. none of the above.
Answer:
None of the above
Step-by-step explanation:
Given
[tex]Design = 2^4[/tex]
Required
Determine the degree of freedom (df)
df is calculated as follows;
[tex]df = N- 1[/tex]
In this case:
N = Number of designs,
[tex]N = 2^4[/tex]
[tex]N = 16[/tex]
Substitute 16 for N in [tex]df = N- 1[/tex]
[tex]df = 16 -1[/tex]
[tex]df = 15[/tex]
Hence, none of the options answer te question
