Answer:
9. -6x+10
10. -24x +18y
11. 15y - 10z
12. -8x- 28
13. -7x + 14
14. -24x +12
Step-by-step explanation:
Y = -7
x = -19
Steps:
Add the two equations together:
y - x + y + x = -14
2y = -14
y = -7
-7 + x = -26
x = -19
Answer:
1/15
Step-by-step explanation:
Ms. Fox loves to eat cereal and she notices that she only has 1/3 of the box of cereal left. If she spread that amount across 5 days, how much cereal will she have for each day?
The amount of cereal she would have per day is calculated as:
5 days = 1/3 of the box
1 day = x
Cross Multiply
5 days × x = 1 day × 1/3 of the box
x = 1/3 ÷ 5
x = 1/3 × 1/5
x = 1/15 of the box
