Answer:
The correct option is (b).
Step-by-step explanation:
We need to find the equivalent to -2(4-3x)+(5x-2)
Using the associative property,
-2(4-3x) = -2(4)+2(3x)
= -8+6x
So,
-2(4-3x)+(5x-2) = -8+6x +5x-2
taking like terms together,
-2(4-3x)+(5x-2) = 6x+5x-8-2
= 11x-10
The equivalent expression is equal to (11x-10).
I think 240..
September to next September=12months
the population grows at the rate of 5% so
5×12=60%
150×60%=90
90+150=240
i dont know if im right but...
Answer: After 1.7 hours, they will be 1,000 miles apart.
Step-by-step explanation:
Let t represent the time it will take both planes to be 1000 miles apart.
If both planes leave the airport at 10.00am, it means that they would have covered a total distance of 1000 miles after t hours.
Distance = speed × time
If the northbound plane flies at 280 mph, it means that the distance covered in t hours is 280t.
If the southbound plane flies at 320 mph, it means that the distance covered in t hours is 320t.
Since the total distance covered is 1000 miles, then
280t + 320t = 1000
600t = 1000
t = 1000/600
t = 1.7 hours
Answer:
The equivalent expression would be 3^6, and without exponents this would be equal to 729.
Step-by-step explanation:
To get the equivalent expression, you have to know that terms with the same base that are multiplied simply add together exponents.
3^4 * 3^2 = 3^6
Then we can find that by expanding the terms and completing the multiplication.
3 * 3 * 3 * 3 * 3 * 3 = 729
