Answer:
Picture 3
Step-by-step explanation:
The easiest method is to see if (0,0) is the solution.
1. <em>The line y ≤ -3x + 2 is the line pointing down, and y - x ≥ 2 is the line pointing up</em>, since negative slopes go bottom-right.
2. y - x ≥ 2 --> plug in numbers: 0 - 0 ≥ 2 --> Not true --> the line pointing up's shading will go up, to avoid (0,0) --> <em>Picture 3 is right</em>.
3 (not needed in this situation). y ≤ -3x + 2 --> 0 ≤ 0 + 2 --> True --> The line pointing bottom right has (0,0) --> <em>Picture 2 or 3 is right</em>.
The overlap of possible answers is picture 3.

2/3 of a basket of apples rot. We eat 4/5 of the rest and use the remaining 25 to make jam. How many apples were in the basket
Answer:
375
Step-by-step explanation:
Since the basket was full, ⅔ rot so the remaining for any use will be 1-⅔=⅓
Since we only eat 4/5 of this remaining quantity, we use the 1-4/5=1/5 of ⅓ for making jam
1/5 of ⅓=1/5*⅓=1/15
If 1/15 equals 25 pieces then the full basket had
25*15/1=375 pieces

Perimeter
3 * (1/2) * (6π) + (1/2) * (18π) = 18π cm
Area
3 * (1/2) * ((3 ^ 2) π) + (1/2) * ((9) ^ 2π) = 54π cm ^ 2

Perimeter
6 * (1/2) * (4π) + 2 * (4) = (12π + 8) cm

Perimeter
2 * (1/2) * (6π) + (1/2) * (12π) + 2 * (6) = (12π + 12) cm
Area
2 * (6 * 6) + (1/2) * ((6) ^ 2π) = (18π + 72) cm ^ 2
Answer:
D. 15G > 9
Step-by-step explanation:
Given: G = 3/5
Here we have to check each options and find which is true.
Let's start from A.
G - 1 > 2/5
G > 2/5 + 1
G > 7/5 is not true.
B. -10G > 6
Dividing both sides by -10 , we get
G < -6/10
G < -3/5 Is not true.
C. 1 2/5 + G > 3
Now convert 1 2/5 to improper fraction.
1 2/5 = 7/5
7/5 + G > 3
G > 3 - 7/5
G > (15 - 7)/5
G > 8/5 is not rule.
D. 15G > 9
Dividing both sides by 15, we get
G > 9/15
Now we have to simplify 9/15
G > 3/5 which is true.
Answer: D. 15G > 9
Thank you.
