Answer:
look at explanation (I go down the first column of scenarios and then move on to the right column)
Step-by-step explanation:
1) The first one will be same as original because the decrease and increase are the same, and happen right after each other so you get the same amount
2) Second one you get greater than original. You're doubling the initial value, and then decreasing by a smaller percentage, so you still get greater than your initial value
3) Third you get greater than original. You're adding 50% of the initial value, and decreasing by 33.5% of the new value, which will still give you more than the original
4) Fourth, you get greater than original. You're adding 60% of the initial value, and then decreasing by 40% of the new value, which will still give you greater than the initial value
5) Fifth you get less than the original. You're decreasing by 75%, and then adding 50% of the new value, which still gives you less than the initial value
Answer:
n is
, p is
, and r has infinitely many different lines that have this property.
Step-by-step explanation:
If two lines have no solutions, that means that they are parallel. The slopes of two lines are the same if they are parallel. So n's slope is
. The y-intercept can be anything except -5, or +b. If two lines have infinitely many solutions, those two lines are exactly the same. So p is just m. If two lines have one and only one solution, that just means the slopes and y-intercepts are different. Since we don't know anything else about line r, we an't model an equation for it.
Answer:
Cheryl is correct.
Step-by-step explanation:
Cheryl solved a problem : 84 ÷ 0.01 = 8,400.
This is absolutely right.
When we divide any whole number with the divisor having decimal, we change the divisor to a whole number before performing the division.
To do this, we multiply both the numbers (divisor and dividend) by the same power of 10, until the divisor is a whole number.
= 
to make divisor a whole number we will again multiply both the numbers by 10.
=
= 8,400
Now answer would be 8400.
Therefore, Cheryl is correct.
