What is 3/x+6=x/9 ? add

Mathematics
1 answer:
Mkey [24]2 years ago
4 0

Let's solve your equation step-by-step.

3x+6=x9

Step 1: Cross-multiply.

3x+6=x9

(3)*(9)=x*(x+6)

27=x2+6x

Step 2: Subtract x^2+6x from both sides.

27−(x2+6x)=x2+6x−(x2+6x)

−x2−6x+27=0

Step 3: Factor left side of equation.

(−x+3)(x+9)=0

Step 4: Set factors equal to 0.

−x+3=0 or x+9=0

x=3 or x=−9

Suppose your dog posit $250 in a new savings account paying a Yield of 3% interest if the count is left alone how much money wil
Fed [463]

Answer:

The amount after a time period of 5 years is $287.5.

Step-by-step explanation:

Principal Amount  deposited   =  $250

Time  = 5 Years

Rate of interest = 3%

Now, SIMPLE INTEREST = \frac{P \times R \times T}{100}

⇒SI = \frac{250  \times 3  \times 5}{100}   = 37.5

or, the interest amount after 5 years = $37.5

Now, AMOUNT = PRINCIPAL + INTEREST

                             =  $250  + $37.5  = $287.5

Hence the amount after a time period of 5 years is $287.5.

Use the power rule (which says to multiply the exponents)

1) n⁴ˣ⁸ = n³²

2) x³ˣ⁻⁵ = x⁻¹⁵ = \frac{1}{x^{15} }

3) c³ˣ⁵ * d³ˣ⁰ = c¹⁵ * d⁰ = c¹⁵ * 1 = c¹⁵

1/2x-9=-25 what is your answer
Elodia [21]
First, let's only the expression with x stay on the let side: let's add 9 to both sides of the equation.

\frac{1}{2} x-9+9=-25+9
which is
\frac{1}{2}x=-16


now, let's multiply everything by 2:

\frac{2}{2} x=-16*2
x=-32


so the answer is -32!

Troyanec [42]

Answer:

120

Step-by-step explanation:

Im not sure but 1.25 equals 1 1/4   and 16 cups equal a gallon.

16 divided by 1.25 is 12 which means that 12 of those ten servings equal a gallon.  10 times 12 is 120 which becomes ur answer. Once again im not sure but i hope that ive helped.
