katelyn has taken 4 math quizzes. Her scores were 75,80,97, and 92. What must she get on her next quiz to have an average of at

Vilka [71]

To find the average add all the numbers together then divide by how many numbers there are.

75+80+97+92=344 divided by 4 = 86

So her average right now is 86.

She’d have to make 96 to get an average of 88.

75+80+97+92+96=440 divided by 5=88

The answer is 96

Quick math question ghghghujhghj

$\text{Hey there!}$

$\bf{3(4x + 1) - (5x + 7)}$

$\text{FIRST: distribute the NEGATIVE sign}$ $\text{(On the RIGHT side of the problem/equation)}$

$\bf{-1 (5x + 7)}$

$\bf{-1(5x) + -1(7)}$

$\bf{-1(5x) = -5x}$

$\bf{-1(7) = -7}$

$\bf{\underline{= -5x - 7}}$

$\text{SECOND: distribute the LEFT side of the problem/equation}$

$\bf{3(4x+1)}$

$\bf{3(4x) + 3(1)}$

$\bf{3(4x) = 12x}$

$\bf{3(1) = 3}$

$\bf{\underline{12x+3}}$

$\text{THIRD: make the new equation}$

$\text{Equation becomes: \bf{12x + 3 - 5x - 7}}$

$\text{FOURTH: COMBINE your like terms}$

$\bf{(12x - 5x) + (3 - 7)}$

$\bf{12x - 5x = 7x}$

$\bf{3 - 7 = -4}$

$\text{ANSWER}$

$\boxed{\text{Thus, your answer is: \boxed{\huge\text{\bf7x - 4}}}}}\checkmark$

$\text{Good luck on your assignment and enjoy your day!}$
