Answer:
a = Negative one-fifth
Step-by-step explanation:
The given equation is :
We need to find the value of a.
Subtract 2/5 from both sides.
So, the correct answer is Negative one-fifth. Hence, the correct option is (b).
Answer:
NOT a rational expression.
Step-by-step explanation:
A rational expression is a fraction of two polynomials.
Since the denominator contains a square-root radical, it is not considered a polynomial.
Therefore the given exprssion is NOT a rational expression.
Answer:
p = -2
Step-by-step explanation:
O we have to solve this equation:
24p + 12 - 18p = 10 + 2p - 6
First, we will operate what we have in both sides:
24p - 18p + 12 = 10 - 6 + 2p
6p + 12 = 4 + 2p
We substract 2p in both sides and 12 too.
6p + 12 - 2p - 12 = 4 + 2p - 2p - 12
4p = -8
Now, we divide both sides by 4
4p/4 = -8/4
Answer:
The shorter piece is 28 inches
The long piece is 56 inches
Step-by-step explanation:
First, we need to write an equation:
-> Let x be the shorter piece after they are cut.
84 inches = x + 2x
84 inches = 3x
28 inches = x
x = 28 inches
Now we will find the length of each piece,
-> The shorter piece is 28 inches
[] x = 28 inches
-> The long piece is 56 inches
[] 2x = 2(28) = 56 inches
Checking work:
56 + 28 = 84
-> This solution should work
