What is the answer to the equation 3(x+4.5)=36?

kozerog [31]

Answer:

$x = 7.5$

Step-by-step explanation:

$3(x + 4.5) = 36$

$3x + 13.5 = 36$

$3x = 36 - 13.5$

$3x = 22.5$

$x = \frac{22.5}{3}$

$x = 7.5$

Jake's test scores are 86, 70, 72, 100, 96, and 80. What must Jake earn of his last test to earn a mean grade of exactly 85%?

kompoz [17]

Answer:

91

Step-by-step explanation:

Mean is calculated as

mean = $\frac{sum}{count}$

let x be his test score of his last test , then

$\frac{86+70+72+100+96+80+x}{7}$ = 85 ( multiply both sides by 7 )

504 + x = 595 ( subtract 504 from both sides )

x = 91
