Answer:
8/21
Step-by-step explanation:
The total job is 1
Mike has done 1/3 and Dena has done 2/7 of the job We still need to do x of the job to complete it
1/3 + 2/7+ x = 1
We need to get a common denominator 3*7 = 21
Multiply each side by 21
21(1/3 + 2/7+ x) = 1*21
21(1/3) + 21*(2/7)+ 21x = 21
7+ 3*2 +21x =21
7+6+21x = 21
13+21x = 21
Subtract 13 from each side
13-13+21x=21-13
21x = 8
Divide each side by 21
21x/21 = 8/21
x = 8/21
We need to complete 8/21 of the job
Answer:
4. 2(3k+4y-14).
5. 76+34.9.
6.10t-8
Step-by-step explanation:
4.since it's 6k+8y-14 all of the numbers can be divided by 2 then the you just put a 2 in front of everything and then(3k+4y-14).
5. (22+11.5x)+(54+23.4x).
=(22+54)+(11.5x+23.4x).
=76+34.9x.
=34.9x+76.
6.(9t-3)+(-5+t).
=(9t+t)+(-3-5).
=10t-8.
