Givens

Start = S = - 700

# Correct = C = 8

Value Correct = VC = 400

# Incorrect =I = 9

Value Incorrect =VI =  - 600

Equation

Score = S + C*VC + I*VI         Substitute

Solve

Score = -700 + 8*400 + 9(-600)

Score = -700 + 3200 - 5400

Score = - 700 - 2200

Score = - 2900 <<<<< Answer

Solve using the method of elimination and determine if the system has 1 solution, no solutions, or infinite solutions
Minchanka [31]

\begin{array}{rrrrr} 10x&-&18y&=&2\\ -5x&+&9y&=&-1 \end{array}~\hfill \implies ~\hfill \stackrel{\textit{second equation }\times 2}{ \begin{array}{rrrrr} 10x&-&18y&=&2\\ 2(-5x&+&9y&)=&2(-1) \end{array}} \\\\[-0.35em] ~\dotfill\\\\ \begin{array}{rrrrr} 10x&-&18y&=&2\\ -10x&+&18y&=&-2\\\cline{1-5} 0&+&0&=&0 \end{array}\qquad \impliedby \textit{another way of saying \underline{infinite solutions}}

if we were to solve both equations for "y", we'd get

10x-18y=2\implies 10x-2=18y\implies \cfrac{10x-2}{18}=y\implies \cfrac{5}{9}x-\cfrac{1}{9}=y \\\\\\ -5x+9y=-1\implies 9y=5x-1\implies y=\cfrac{5x-1}{9}\implies y = \cfrac{5}{9}x-\cfrac{1}{9}

notice, the 1st equation is really the 2nd in disguise, since both lines are just pancaked on top of each other, every point in the lines is a solution or an intersection, and since both go to infinity, well, there you have it.

romanna [79]

Answer:

The gallons of gas the tank contain now is <u>35 1/12</u>.

Step-by-step explanation:

Given:

Fuel tank contains 1 3/4 gallons of gasoline.

Casey adds 33 1/3 gallons of  gasoline to the tank.

Now, to find the total gallons of gas the tank contain.

Converting the mixed fractions into improper.

Gallons of gasoline in fuel tank =1\frac{3}{4}=\frac{7}{4}.

Gallons of gasoline Casey adds =33\frac{1}{3} =\frac{100}{3}.

<u>According to question:</u>

By adding we get the total gallons of gasoline now tank contain:

\frac{7}{4} +\frac{100}{3}

=\frac{7\times 3+100\times 4}{12}

=\frac{21+400}{12}

=\frac{421}{12}

=35\frac{1}{12}

Therefore, the gallons of gas the tank contain now is 35 1/12.

Help clear the fractions I need more help
marishachu [46]

Answer:

x = \frac{43}{6}

Step-by-step explanation:

Given

\frac{3}{4} x - 5 = \frac{3}{8}

Multiply through by 8 ( the LCM of 4 and 8 ) to clear the fractions

6x - 40 = 3 ( add 40 to both sides )

6x = 43 ( divide both sides by 6 )

x = \frac{43}{6}
