A blue parachute that falls 12 feet in 6 seconds
Answer:
2. A
3. C
4. B
Step-by-step explanation:
2. To answer # 2, just add all the sides together...
(5x-7) + (3x-4) + (2x-6)
= 10x - 17
3. To answer # 3, divide/mulitply both the numerators and denominators by the same number and check to see if that answer matches the displayed answer...
a) 28 divided by 7 is 4, so divide the whole fraction by 7 to see if the fraction is proportional...
28/7 = 4
49/7 = 7
b) 4 goes into 16 4 times so multiply
by 4...
4 x 4 = 16
7 x 4 = 28
= 
c) 4 goes into 16 4 times so multiply the whole fraction by 4...
4 x 4 = 16
7 x 4 = 28
≠ 
d) 4 goes into 20 5 times to multiply the whole fraction by 5...
4 x 5 = 20
7 x 5 = 35

C is the answer because the fractions are not proportional.
4) 25% is a quarter of 100%. A third of 100% is 75%.
$120 - 0.25($120) = $90
Another expression for the for sale price is...
B) 0.75($120) = $90
Answer:
Step-by-step explanation:
Answer:
Less than 5
Step-by-step explanation:
The eason behind the answer being less than 5 is because if you multiply something by a fraction that is less than a whole number, then you will get less than the original number you multiplied the fraction with.
Hope this helps :)
Answer:
The answer to your question is:
Step-by-step explanation:
(a + b)¹²
a¹² + 12a¹¹b + 66a¹⁰b² + 220a⁹b³ + 495a⁸b⁴ + 792a⁷b⁵ + 924a⁶b⁶ + 792a⁵b⁷
+ 495a⁴b⁸ + 220a³b⁹ + 66a²b¹⁰ + 12ab¹¹ + b¹²
a. a²b¹⁰ = 66
b. a⁵b⁷ = 792
c. a⁸b⁴ = 495
