3x + (5+35x) = 3x -30
38x + 5 = 3x -30
38x = 3x -35
35x = -35
x = -1
Answer:
10 7/12 hours
Step-by-step explanation:
so we have to multiply 2 2/3 twice since he does that many hours for 2 days. We then have to multiply 1 3/4 three times since he does that many hours for 3 days. Lets first convert 2 2/3 into a mixed fraction. 2 2/3 = 3 times 2 =6 +2=8 over 3. 1 3/4=4 times 1=4+3=7 over 4. 8/3 times 2 equals 16/3 which eqials
5 1/3 hours. 7/4 times 3 equals to 21/4 which equals to 5 1/4. Lets now add
5 1/3 and 5 1/4. 5+5=10 but the fractions are not the same. Therefore, we need to make it to a common denominator. 4 times 3 equals to 12 so 4/12 plus 3/12 equals 7/12. Final answer equals to 10 7/12.
27x-6=9x-1
27x-9x =-1+6
18x = 5
x = 5/18
