Answer:

-144 is your answer for x.

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.

Do the opposite of PEMDAS. PEMDAS is the order of operation, and stand for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, subtract 12 from both sides of the equation:

x/6 + 12 (-12) = -12 (-12)

x/6 = -12 - 12

x/6 = -24

Next, isolate the variable x, by multiplying 6 to both sides:

(x/6) * 6 = (-24) * 6

x = -24 * 6

x = -144

-144 is your answer for x.

The graph shows the type and number of coins that three students plan to donate during a coin drivefundraiser.Coin Drive Donatio
yarga [219]

Answer:

39 dimes

Explanation:

From the graph:

• Total number of nickels = 9+4+7=20

,

• Total number of dimes = 7+10+9 = 26

The ratio of total nickels to total dimes = 20:26

If the total number of nickels the students donate is increased to 30, we have:

\frac{\text{Total Nickels}}{\text{Total Dime}}\colon\frac{20}{26}=\frac{30}{x}

We then solve for x:

\begin{gathered} 20x=30\times26 \\ x=\frac{30\times26}{20} \\ x=39 \end{gathered}

The number of dimes they should donate to keep the ratio of total nickels to total dimes the same is 39.

Solve the system of equations.<br> – 7x – 10y = 45<br> -3x - 5y = 25<br> x =<br> Y =
irina [24]

Answer:

The solution is (-5, -2).

Step-by-step explanation:

We'll use "elimination by addition and subtraction."

Multiply the second row by -2.  Our system

– 7x – 10y = 45

-3x - 5y = 25

becomes:

– 7x – 10y = 45

+6x  + 10 y = -50

-------------------------

  -x             =  5, so that x = -5.

Substituting -5 for x in the second equation results in

-3(-5) - 5y = 25, or  15 - 5y = 25.  This reduces to

-5y = 10, so that y must be -2.

The solution is (-5, -2).
