Answer:
x = -2, y=1
Step-by-step explanation:
x-7y=-9---------------------equation 1
-x+8y=10-------------------equation 2
From equation 1, make x the subject of formula
x=7y-9----------------------equation 3
substituting x=7y-9 in equation 2,
-(7y-9)+8y=10
Expanding bracket
-7y+9+8y=10
Collecting like terms
8y-7y=10-9
y=1
substituting y=1 in 3
x=7(1)-9
x=7-9
x=-2
Answer:
C. 16 : 22
Step-by-step explanation:
Given:
- Apple trees = 16
- Orange trees = 22
- Cherry trees = 1
Ratio of apples trees to orange trees:
⇒ apple : orange
⇒ 16 : 22
Okay. so, there are 1,440 minutes in one day. 1,440 * 365 is 525,600. There are 525,600 minutes in one year. 525,600 * 78 is 40,996,800. The average person lives 40,996,800, which is without a doubt way over 1 million minutes, so yes. The average person lives over 1 million minutes. Living 1 million minutes or less would mean that you would live less than 2 years. That's just barely starting to enter the toddler years.
