7. Let x be the money she began with, then
1/3 (x - 4/5 x) = 15
1/3 (1/5 x) = 15
1/15 x = 15
x = 15 * 15 = $225
Therefore, she started with $225
Let x be the number of students surveyed, then
1/2(x - 1/3x - 1/6x) = 9
1/2(1/2x) = 9
1/4x = 9
x = 4 * 9 = 36
Therefore, the number of students surveyed is 36.

Answer:
N = 4 × 3 × 1 = 12 outcomes.
The number of outcomes in the event that Pablo picks one marble of each color N = 12 outcomes
Step-by-step explanation:
Given;
Number of red marbles = 4
Number of green marbles = 3
Number of yellow marbles = 1
The number of outcomes in the event that Pablo picks one marble of each color N;
That means he picks 1 red, 1 green and 1 yellow marble.
N = 4 outcomes for red × 3 outcomes for green × 1 outcome for yellow.
N = 4 × 3 × 1 = 12 outcomes.
The number of outcomes in the event that Pablo picks one marble of each color N = 12 outcomes
Answer:
25 bananas
Step-by-step explanation:
You halved the strawberry number (from 40 to 20) ....half the banana number = 25
The point ton the line is parallel to the x-axis, and at a distance 5 units from the origin in <span>the negative direction of y-axis.
</span>⇒ (0, -5)
When y = -5,
4x + 7y = -11
4x + 7(-5) = -11
4x - 35 = -11
4x = 24
x = 24 ÷ 4
x = 6
