Answer:
3(x-1)
Step-by-step explanation:
you need to out the x minus 1 in brackets as you multiply the whole thing by 3
-2(7)*18
You do -2 times 7 you get an answer then with that number you multiple with 18
Answer: ~ 6.8 or round up to ~7 minutes
Step-by-step explanation:
You first subtrat the $8 monthly cost pay from the $12.08
Which leaves you with $4:08
Divide 4.08 by 6 and you get .68
Move the decimal over and you get your answer
The solution is (2, -4).
We can solve this with the elimination method. Multiply the first equation by -2 and then add the two equations.
-20x + -12y = 8
20x + 10y = 0 Add the two equations
-2y = 8
y = -4
Now, just input -4 for y into either equation, you will get 2 for x.
5.76 since length times width is area so you do 2.4 x 2.4
