Answer:
Step-by-step explanation:
Work via factoring by groups:
!) re arrange the terms as follows:
then extract the common factor for the first two terms (a), and separately the common factors for the last two terms (3 b):
Now notice that the binomial factor (a-5 b) is in both expressions, so extract it:
which is the final factorization.
Answer:
c) 20
Step-by-step explanation:
The circumference is given by
C= pi *d
Substitute in what we know
62.8 = 3.14*d
Divide by 3.14
62.8/3.14 =3.14d/3.14
20 =d
Answer:
The inequality that represents this statement is 99 + 0.2*miles <= 200 and Melissa has to drive 505 miles or less on her vacation.
Step-by-step explanation:
In order to solve this problem we can first create an equation that represents the total paid in function of the miles driven. We have:
total paid = 99 + 0.2*miles
Since Melissa can oly pay $200 for the rent, then the total paid by her must be less or equal to this value so we have:
99 + 0.2*miles <= 200
0.2*miles <= 200 - 99
0.2*miles <= 101
miles <= 101/0.2
miles <= 505 miles
The inequality that represents this statement is 99 + 0.2*miles <= 200 and Melissa has to drive 505 miles or less on her vacation.
