Answer:
k=4
Step-by-step explanation:
-127=2k-5(5k+7)
Distribute the -5 to the 5k and 7 to give you -25k - 35
-127=2k-25k-35
Combine like terms (2k - 25k)
-127=-23k - 35
Add 35 to both sides
-92=-23k
Divide both sides by -23
k=4
121 right because 87+34 is 121 but do i have to round the number
The answer is 1because a number is multiple by 20 then 200 and multiple by 3 -7=1
So 1/7 divided by 8
equals to 1/ 56 tons per trip
First simplify the expression: 3 x 6^2
3 x 36 = 108
