Answer:
8.9
Step-by-step explanation:
64<80<81
√64<√80<√81
8<√80<9
Now evaluate (8.8)² = 77 and 11/25
hence the next decimal place must be greater than eight. Hence 8.9 is an estimate to the nearest tenth.
8=-2/5c
8 divided by -2/5
answer: -20
Answer:
(56/45)x^7
Step-by-step explanation:
28x^4 20
---------- ÷ ----------- becomes
27 24x^3
28x^4 24x^3
---------- * ----------- if we invert the divisor fraction and then multiply.
27 20
We get: (28)(24)
-------------- x^7
(27)(20)
which reduces to (7)(24) x^7 (7)(8)x^7
--------------- = ------------- = (56/45)x^7
27(5) 9(5)
Answer:
See below
Step-by-step explanation:
"Like terms" are terms with the same variable or exponents.
You can add or subtract these just like you would with regular numbers.
Examples:
2x + 4x = 6x
5xy + 7xy = 12xy
6 + 5 = 11
Let me know if you need more examples or have any questions :)
The second one and the 4th one are the correct answers, if I'm not mistaken
