How I divide by negative?? I forgot completely
Answer:
I hope this helps. If I misunderstood the question let me know
Step-by-step explanation:
1. When dividing a negative by a negative, your answer would be positive.
2. When dividing a negative by a positive, your answer will be negative.
3. When dividing a positive by a negative,your answer will be negative.
Divide like you normally would, the result will be the same as positive-number-quotients, but the quotient will be negative.
Example:
10 ÷ -5
since 5 is the dividend, 5 goes into 10 two times but note that it's negative two because of the negative division logic.
= -2

What is 2 ÷ 1/2 (fraction)
Please explain steps too
Answer:
4
Step-by-step explanation:
if you add 1/2 4 times, it will equal 2.
1/2 + 1/2 = 1
1 + 1/2 = 1.5
1.5 + 1/2 = 2
[tex]2 \div \frac{1}{2} [/tex]
solution:[tex] \frac{2}{1} \div \frac{1}{2} [/tex]
[tex] = \frac{2 \times 2}{1 \times 1} [/tex]
[tex] = \frac{4}{1} [/tex]
[tex] = 4[/tex]
hence, the correct answer is 4

Solve the following equation systems using the elimintation mathod
2y - x = 8
-3x + 2y = -12
original equation
[tex]2y-x=8\\-3x+2y=-12\\[/tex]
line up your terms
[tex]2y-x=8\\\\2y-3x=-12[/tex]
since they are both positive, subtract
[tex]2x=20[/tex]
solve for x
[tex]x=10[/tex]
substitute into one of the equations and solve for y
[tex]2y-(10)=8\\\\2y=18\\\\y=9[/tex]
verify
[tex]2(9)-(10)=8\\\\18-10=9\\\\8=8\\\\LS=RS[/tex]
[tex]-3(10)+2(9)=-12\\\\-30+18=-12\\\\-12=-12\\\\LS=RS[/tex]

Answer:
Favorite chip Answers v
Step-by-step explanation:
1. How many were surveyed? 82+8+18+62=100
2. How many said Jalepeno was their favorite? 8/100 0r 2/25 or 8%
3. How many said BBQ was their favorite?62/100 or 31/50 or 62%
4. How would it effect your final answer if the percentages did not add up to 100%? This means that your percentages are wrong. In a circle graph the percentages always equal 100%!
5. Is it possible to determine a missing percentage in a circle graph? Yes, we can always assume the total percentage is 100 so you add your given percentages together and then subtract that total from 100 to find the missing percentage.
