Answer:
D (-3, 5)
Step-by-step explanation:
270 counter clockwise is the same as 90 clockwise.
For a 90° clockwise or 270° counter clockwise, take the opposite of the x coordinate then switch the coordinates.
(-5, -3) -----> (5, -3) ------> (-3, 5)
You can also rotate your screen 90° clockwise to see the new coordinates for A.
Answer: 112.5
Step-by-step explanation:
The question really is asking whats 45% of 250
1. Calculate 10% of the total
2. Calculate 5% of the total
3. Solve for 40% of the total
4. Add 5% of the total
1. 10% of 250
250 = 100%
*divide both sides by 10*
25 = 10%
2. 5% of 250
25 = 10%
*divide both sides by 2*
12.5 = 5%
3. 40% of 250
10% + 10% + 10% + 10% = 40%
25 + 25 + 25 + 25 = 40%
50 + 50 = 40%
100 = 40%
4. 45% of 250
100 = 40%
12.5 = 5%
100 + 12.5 = 40% + 5%
<em>112.5 = 45%</em>
A) if 18 muffins = 1 box,
1020 muffins = 1020/18 boxes
= 56.67 boxes
So they used 56 full boxes.
b) if 25 cookies = 1 bag
2820 cookies = 2820/25 bags
= 112.8 bags
So they used 112 full bags.
c) the remainders from a and b represent muffins and cookies left over.
Answer:

Step-by-step explanation:
Given equation:

Solving for unknown variable 
Adding 8 both sides by additive property of equality.


Squaring both sides to remove the square root.


Adding 5 both sides by additive property of equality.


Dividing both sides by 6 to isolate 

∴ 
2(n+7) =3n
n = 14
