Answer:
25
Step-by-step explanation:
In her first 5 days, she reads 80 pages. That means that per day, she reads 16 pages. Then, she had 400 pages left, since 480-80 = 400.
So, you divide 400/16 = 25 days.
Answer:
11%
Step-by-step explanation:
<em>Percentage increase = (New average- previous average)/previous average x 100</em>
<em>New average: 1554</em>
<em>Previous average: 1400</em>
Percentage increase = (1554-1400)/1400 x 100
Percentage increase = 154/1400 x 100
Percentage increase = 0.11 x 100
Percentage increase = 11%
Therefore, the average increased by 11%.

Answer:
1. x = 30
2. x = 39
Step-by-step explanation:
1.
4x and ( 3x + 30 ) are alternate exterior angles,
Alternate exterior angles are equal.
4x = 3x + 30
4x - 3x = 30
x = 30
2.
x and ( 3x + 24 ) are co - interior angles.
Sum of co - interior angles is 180,
x + 3x + 24 = 180
4x + 24 = 180
4x = 180 - 24
4x = 156
x = 156 / 4
x = 39
