Answer:

C = 5/8 (F - 32)

C × 8 = 5/8 × 8 (F - 32)

8C = 5(F - 32)

$\frac{8C}{5} = \frac{5(F - 32)}{5}$

$\frac{8C}{5}$ = F - 32

$\frac{8C}{5} + 32$ = F - 32 + 32

$\frac{8C}{5} + 32$ = F

C = 22

F = $\frac{8C}{5} + 32$

F = $\frac{8(22)}{5} + 32$

F = $\frac{176}{5} + 32$

F = 35.2 + 32

F = 67.2

Alexandra [31]

Answer:

Difference in scores between his 7th and 8th quizzes = 22

Step-by-step explanation:

Given: Mean score for first 6 quizzes is 33 points. After his 7th quiz his mean score was 32 points. After the 8th quiz the mean was 34.

To find: difference in scores between his 7th and 8th quizzes

Solution:

Mean scores = Total points scored in quizzes ÷ Number of quizzes

So,

Total points scored in quizzes = Mean scores × Number of quizzes

As mean score for first 6 quizzes is 33 points,

Total points scored in 6 quizzes = 6 × 33 = 198

As mean score for first 7 quizzes is 32 points,

Total points scored in 7 quizzes = 7 × 32 = 224

So,

7th score = Total points scored in 7 quizzes - Total points scored in 6 quizzes

= 224 - 198

= 26

As mean score for first 8 quizzes is 34 points,

Total points scored in 8 quizzes = 8 × 34 = 272

So,

8th score = Total points scored in 8 quizzes - Total points scored in 7 quizzes

= 272 - 224

= 48

Therefore,

Difference in scores between his 7th and 8th quizzes = 48 - 26

= 22
