Answer:
x=−2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−3x−32=−2(5−4x)
−3x+−32=(−2)(5)+(−2)(−4x)(Distribute)
−3x+−32=−10+8x
−3x−32=8x−10
Step 2: Subtract 8x from both sides.
−3x−32−8x=8x−10−8x
−11x−32=−10
Step 3: Add 32 to both sides.
−11x−32+32=−10+32
−11x=22
Step 4: Divide both sides by -11.
−11x
−11
=
22
−11
What we know:
1/6 = what Cody wathed
1 stands for the unit that cody has watched a move (minutes)
6 = stands for the entire length of the movie (minutes)
Tharefore: If 6 stands for the entire length of the movie the movie is equal to 3 hours. However we are giving the unit in minutes not in hours, it would be:
3 x 60 = 3 stands for the ours 60 stands for minutes in an hour. That equals to 180.
This means that the 6 = 100% = 180min of the movie.
To figure what 1 stands for we need to divide 1/6. That will equal to 0.1(6). 0.1(6) x 180 (minutes of the entire movie) = 30 which would be the answer. Here is what you should have done using mathematical communication:
converting 3 h to minutes:
3 x 60 = 180 minutes
180 = the length of the entire movie
1/6 = 0.1(6)
0.1(6) x 180 = 30
... 30 /180 is the fraction of minutes that Cody spend watching the movie
in other words Cody just spent 30 min watching the movie.
Answer:
it is exponent less than 1
A. -5 i think it is the right answer
Answer:
48
Step-by-step explanation:
7x+42=11(3x+8)−2(13x−1)
Step 1: Simplify both sides of the equation.
7x+42=11(3x+8)−2(13x−1)
7x+42=(11)(3x)+(11)(8)+(−2)(13x)+(−2)(−1)(Distribute)
7x+42=33x+88+−26x+2
7x+42=(33x+−26x)+(88+2)(Combine Like Terms)
7x+42=7x+90
7x+42=7x+90
Step 2: Subtract 7x from both sides.
7x+42−7x=7x+90−7x
42=90
Step 3: Subtract 42 from both sides.
42−42=90−42
0=48
