Answer: the last one
Step-by-step explanation:
Answer:
Is there a x somewhere or is that litteraly how the equation is?
If so, -7 multiplied by 2 is -14,
-1 times -7 is 7,
add it together and you get
-7=28,
you could add 7 to both sides or subtract 28 from both sides and you'll get either 0=35 or -35=0
which would make the solution false since both sides are not the same
Answer:
30% of the sodas were regular sodas
Step-by-step explanation:
Add 21 and 49 to get the total number of sodas and 21+49=70. To get the percentage, divide 21 by 70 (21÷70) is 0.3 or 30%.
To check, do 30% (or 0.3) • 70 and you will get 21.
Given:
yesterday = 270
today = 216
yesterday's number of tickets sold is the basis of the percent of change. So, 270 is the 100%.
270 - 216 = 54 * value of the change in ticket sales
54/270 = 0.20 x 100% = 20% * percent of change
There was a 20% decrease in ticket sales.
