Subtract 8 from both sides -6x< -48 (40 is a negative so -8 will just add to it)
Divide -48 and -6
X< 8 (since they’re both negative it’ll turn into a positive because we divided)

Ksenya-84 [330]

Answer:

"6 out of 10 people" means the ratio of class:no_class is 6:4

990/10 = 99, the smallest the "class" and the "no_class" add up to is 10. And, generally, the total divides with that nicely, as in this case.

99(6) = 594 ----------- probably class

99(4) = 396 ------------------ probably no class

Total  = 990

I hope this helps

Harrison went out to buy coffee for his classmates. There are 23 students in his class, counting Harrison himself. Some wanted m
NemiM [27]

Step-by-step explanation:

Let's represent the number of mochas bought with the variable M, and the number of lattes bought with the variable L.

Since there are 23 students, the total number of mochas and lattes bought must be 23. This can be represented with the following equation:

M + L = 23

We can also set up another equation based on the total amount spent on the coffe:

4.30M + 3.50L = 87.70

If we rearrange the first equation, we can solve for M:

M = 23 - L

If we substitute this into the second equation, we can solve for L:

4.30(23 - L) + 3.50L = 87.70

98.9 - 4.3L + 3.5L = 87.7

98.9 - 0.8L = 87.7

0.8L = 11.2

L = 14

Subtituting this back into the original equation, we can solve for M:

M + L = 23

M + 14 = 23

M = 9

Therefore, 9 mochas and 14 lattes were bought.
