pedro has scores of 88,80.83 and 74 after four tests. what score must he make on his fifth test to have an average of 76 or grea
daser333 [38]

We start to solve this by looking for the formula that let us calculate an average value, this formula would be:

save=\frac{1+s2+s3+s4+s5}{5}

where Save is the average score and s is the score of each exam, Since we know the value of the score Save and 4 of the exams we can replace them in the formula, like this:

And we can solve for s5, which is the score that we need to find, like this:

\begin{gathered} 74\times5=\frac{88+80+83+74+s5}{5}\times5 \\ 74\times5=88+80+83+s5 \\ 74\times5-88-80-83-74=88+80+83+74-88-80-83-74+s5 \\ 74\times5-88-80-83-74=s5 \\ s5=74\times5-88-80-83-74=55 \end{gathered}

Then, Pedro must have a 55 score on the fifth test

Solve the inequality 2x2 + 10x < –8
BigorU [14]

Answer:

-4<x<-1

Step-by-step explanation:

To solve the problem, we divide the whole expression by 2:

2x^2 + 10x < –8 → x^2 + 5x < –4

→  x^2 + 5x + 4 < 0

Factorizing

→ (x+4)(x+1) < 0

The expression is ONLY negative when:

x>-4 and x<-1

Therefore, the solution is:

-4<x<-1
