Answer:
Spelling word questions = 10
vocabulary word questions = 16
Step-by-step explanation:
Let
Spelling word questions = x
vocabulary word questions = y
Total points = 100
Total questions = 26
x + y = 26 (1)
2x + 5y = 100 (2)
From (1)
x = 26 - y
Substitute x = 26 - y into
2x + 5y = 100
2(26 - y) + 5y = 100
52 - 2y + 5y = 100
- 2y + 5y = 100 - 52
3y = 48
y = 48 / 3
= 16
y = 16
Substitute y = 16 into
x + y = 26
x + 16 = 26
x = 26 - 16
= 10
x = 10
Spelling word questions = 10
vocabulary word questions = 16

Answer:
$13.10 represents the rate of change
Step-by-step explanation:
13.1 is the only value in the equation with a variable (g). There is an additional $13.10 charge for every gigabyte used over the limit, and this is the rate of change.
For example, if 5 gigabytes were used over the limit, the charge would be 13.1(5) or $65.50
If the number on the right of the number you're trying to round is greater than 5, round it up. If the number on the right of the number you're trying to round is less than 5, round down.
So you're trying to round to the nearest whole number, look on the number on the right, it's bigger than 5, it's a 7. Therefore, round the whole number up so it would be 7.
