You can sort them on the shapes that are the same or different
So since her balance must be at least 500, her ballance cannot reach 500
so 794-500=294
see how many 25's you can fit into 294
we know that 4 25's =100 and 294 is roughly 300
so 4 times 3=12
we minus one of the 25's because 294 is less than 300 so
the innequality is
>means more than
794-25x>500
Answer:
<u></u>
Explanation:
<u>1. Ratio of campers to counselors in june:</u>
- Ratio = number of campers / number of counselors
- Ratio = 325 campers / 26 counselors
<u />
<u>2. Ratio of campers to counselors in july:</u>
- number of campers = 325 - 265 + 215 = 275
- number of counselors = x (unknown)
<u />
<u>3. Equivalent ratios:</u>
- 325 campers / 26 counselors = 275 campers / x
Solve for x:
- x = (26counselors/325campers) × 275campers = 22 counselors ← answer
Answer:
20n² - 40n + 20
Step-by-step explanation:
(5n - 5)(4n - 4)
= 5n(4n) + 5n(-4) - 5(4n) - 5(-4)
= 20n² - 20n - 20n + 20
= 20n² - 40n + 20
Another way to do this:
(5n - 5)(4n - 4)
= 5(n - 1) * 4(n - 1)
= 20(n - 1)(n - 1)
= 20(n - 1)²
= 20(n² - 2n + 1)
= 20n² - 40n + 20
