Maria scored 72, 97, and 82 on her first three math tests. She wants to have a mean score of 82 for the quarter. How many points

Rom4ik [11]

Answer:

She needs 77 on her last test to earn an 82 for the quarter.

Step-by-step explanation:

Maria scored 72, 97, and 82 on her first three math tests.

She wants to have a mean score of 82 for the quarter.

Let us assume that she must score x on her last test to earn an 82 for the quarter.

So the average score will be,

$=\dfrac{72+97+82+x}{4}$

But the average score is given as 82, so

$\Rightarrow \dfrac{72+97+82+x}{4}=82$

$\Rightarrow 72+97+82+x=82\times 4$

$\Rightarrow 72+97+82+x=328$

$\Rightarrow x=328-72-97-82$

$\Rightarrow x=77$

(High points) please solve both with explanation. I’ll give brainliest.

lawyer [7]

Answer:

$36\frac{9}{16}$

area: 136 cm

perimeter: 48 cm

Step-by-step explanation:

For the first one just subtract

$45\frac{1}{2}=\frac{91}{2}=\frac{364}{8}\\8\frac{7}{8}=\frac{71}{8}\\\frac{364}{8}-\frac{71}{8}=\frac{293}{8}\\\frac{293}{8}=\frac{586}{16}\\\\\frac{586}{16}-\frac{1}{16}=\frac{585}{16}=36\frac{9}{16}$

for the second one you just have to break it into smaller, more digestible pieces (work below)
