The equation is 5c+25b=260 when c+b=12. rearrange that into 12-b=c. substitute and you get 5(12-b)+25b=260. b=10. 12-10=2, so 10 buses and 2 cars were used as transportation for the field trip.
Answer:
Highest to lowest the numbers would be (1/2)^2, (-1)^2, -1 2/5 Putting the "bar 4" somewhere
First we need the numbers exact value meaning
-1 2/5 = -1.4
(-1)^2 = -1
?4 = ?
(1/2)^2 = 0.25
Answer:
12
Step-by-step explanation:
it is a square and 144 is the area
√144
This gives us 12 for each side
20% - think of it like this, you have 100 as a full percentage, to help, bring it down to 10. Now, you just have to figure out what 10/5 is, and that’s 2, so now you know you’re looking at intervals of 2, but since your real number is 100, we add a zero to the 2, making it 20, and putting this into a percentage!!
Hope this helps!!
