Answer:
PQR=133°
Step-by-step explanation:
PQR+RQS = 180
(3x -5)+(x+1)=180
4x -4=180
4x =180+4
4x =184
x=184/4
x=46
PQR= 3x-5=3(46)-5=138-5=133
I hope I helped you^_^
Hello! Could you possibly give an example of what kind of bacteria? The answer varies until you give me a specific situation.
They want you to combine the variables. So
−12x4 + 7x3 + 6x4 − 2x3 =
5x3 − 6x4
So you combine the coefficients, not the variable number, for instance -12+6=-6, and then you simply put the variable in the same place it was. You don't do anything else with it except what I just showed you
hope it helps
Answer:
do you need the value of x?
x=7+6y+2z
-2(7+6y+2z)+5y+2z=-1 -7y=13+2z
-14-12y-4z+5y+2z=-1
-14-7y-2z=-1
-7y-2z=-1+14
-7y-2z=13
To do this you have to divide 3/4 by 1/6. To do this multiply 3/4 by the reciprocal of 1/6. The reciprocal of 1/6 is 6/1. So you have to multiply 3/4 and 6/1. This will give you 18/4. You now simplify it to 4 2/4, which can be simplified even more to 4 1/2. It will take Trevor 4 1/2 days to paint 3/4 of the fence.
BTW- In case you are wondering how long it'll would take him to paint the entire fence, it would be 6 days.
