Answer:
x = 10.25
y = 6.7
Step-by-step explanation:
X = 8 - (-2.25) = 10.25
Y = 6 - 4.2 - (-4.9) = 6.7
24 boxes
6 cookies each
How many dozen cookies do you need
Because theres 24 boxes and there's 6 cookies in each you multiply 6 by 24. That gives you 144. Then because it's asking for dozen (12), you divide 144 by 12 which gives you 12.
Answer:
1. False, 16=8
2. False, 15=243
3. True, 125=125
4. False, 8=9
5. False, 16=64
6. False, 0.0625=2
7. False, 0.0625=0.125
8. True, 64=64

Answer:
(-3, 0)
Step-by-step explanation:
Let's solve this system using the elimination by addition/subtraction method. Begin by writing the two equations one above the other:
5x +2y =-15
2x - 2y =-6
Notice that the y terms cancel each other out:
5x +2y =-15
2x - 2y =-6
------------------
7x = -21
Dividing both sides by 7 results in x = -3.
Subbing -3 for x in either of the given equations leads to finding y:
5(-3) + 2y = -15, or -15 + 2y = -15. This results in 2y = 0, or y = 0.
The solution is (-3, 0).
