23) x =
= -6.666.
24) x =
= -1.7142.
25) x =
= -7.4.
Step-by-step explanation:
Step 1; For
=
, we cross multiply the denominators and get,
3 × (x + 4) = 12 × (x + 6),
3x + 12 = 12x + 72.
We take all the x terms to the LHS and keep the constants on the RHS.
3x - 12x = 72 - 12,
-9x = 60, x =
= -6.6666.
Step 2; For
=
, we cross multiply the denominators and get,
-5 × (x + 12) = 9 × (x - 4),
-5x - 60 = 9x - 36.
We take all the x terms to the LHS and keep the constants on the RHS.
-5x - 9x = -36 + 60,
-14x = 24, x =
= -1.7142.
Step 3; For
=
, we cross multiply the denominators and get,
6 × (x - 8) = 11 × (x - 1),
6x - 48 = 11x - 11.
We take all the x terms to the LHS and keep the constants on the RHS.
6x - 11x = -11 + 48,
-5x = 37, x =
= -7.4.
Answer:
x=0
Step-by-step explanation:
7x - 42x = 0
Combine like terms
-35x = 0
Divide each side by -35
-35x/-35 = 0/-35
x = 0
Answer:

Step-by-step explanation:

Answer:
$13.20 or $2.20
Step-by-step explanation:
Since percents are decimals, we can figure out the tip by multiplying the total by the decimal percent.
11 x .20 = 2.2
Now the answer depends on what you need the answer to be. if you need the total, it's $13.20.
If you need the tip, it's $2.20.
