Answer:

Hence, the system of equations that is used to represent the situation is:

23x+7y=94-----(1)

16x+14y=38------(2)

Step-by-step explanation:

Let x represent the amount of points received for a correct answer and y represent the amount of points for an incorrect answer.

  • You’ve gotten 23 questions correct and only 7 wrong,giving you a total score of 94 points.

So, the equation formed is:

23x+7y=94

  • Your friend, on the other hand, got 16 questions correct and 14 wrong for a total score of 38 points.

So, the equation formed is:

16x+14y=38

Hence, the system of equations that is used to represent the situation is:

23x+7y=94-----(1)

16x+14y=38------(2)

Combine like terms to create an equivalent expression. -3.6-1.9t+1.2+5.1t−3.6−1.9t+1.2+5.1t
Andreyy89

Question

Combine like terms to create an equivalent expression.

-3.6-1.9t+1.2+5.1t

Answer:

3.2t - 2.4

Step-by-step explanation:

Given;

-3.6 - 1.9t + 1.2 + 5.1t

Combining like terms means bringing terms that have "t" together and separately, those that don't have "t" together. i.e

=> − 1.9t + 5.1t - 3.6 + 1.2

=> 3.2t - 2.4

Therefore, the equivalent expression is;

3.2t - 2.4

Step-by-step explanation:

1) Set a linear quation

\frac{22.30}{x}  =  \frac{15}{100}

2) Cross multiply

15x = 22.30 \times 100

3) Multiple the right side

15x = 2230

4) Divide both side by 15

\frac{15x}{15}  =  \frac{2230}{15}

5) Solve the linear equation

x = 148.6666667
