Answer:
6x -3x^4
Step-by-step explanation:
Eliminate parentheses. Since the multiplying coefficient is +1, the parentheses can simply be dropped:
= 3x +2x^4 +3x -5x^4
Add like terms (ones with the same exponent on the variable).
= 3x +3x +2x^4 -5x^4 . . . . . . . group like terms together
= (3+3)x +(2-5)x^4
= 6x -3x^4
Answer:
11/4
Step-by-step explanation:
The question in math symbols 3/4 - 1/2(4*-1)
By Pemdas (order of operations) we start with the parenthesis
3/4 - 1/2(4*-1) = 3/4 - 1/2(-4)
Because there are parenthesis next to a number, this is a multiplication
3/4 - 1/2(-4) = 3/4 - (-2)
The double negative can be converted into a positive
3/4 - (-2) = 3/4 + 2
Then we can convert the 2 into a fraction of fourths
3/4 + 2 = 3/4 + 8/4
Now we just add the numerators and keep the denominator
3/4 + 8/4 = 11/4

Answer:
target speed for the marathon has been achieved and exceeded
Step-by-step explanation:
Given that :
Target speed = 25 mph
Current speed = 15 miles in 1/2 an hour
Current speed :
15 miles in 0.5 hours
X miles in 1 hour
0.5x = 15 miles
X = 15 / 0.5
X = 30 miles per hour
Hence, current speed in miles per hour = 30mph
This means that her target speed for the marathon has been achieved and exceeded
