Answers:
Angle A = 104 degrees
Angle B = 76 degrees
=================================
Supplementary angles add to 180 degrees.
A+B = 180
(3x-7)+(2x+2) = 180
5x-5 = 180
5x-5+5 = 180+5 ... add 5 to both sides
5x = 185
5x/5 = 185/5 .... divide both sides by 5
x = 37
Use x =37 to find
Angle A = 3x-7 = 3*37-7 = 111-7 = 104 degrees
Angle B = 2x+2 = 2*37+2 = 74+2 = 76 degrees
As a check: A+B = 104+76 = 180 so that helps confirm the answer
Answer:
C. 3.33 hours
Step-by-step explanation:
Use the algebra work equation:
= 
+ 
, where tb is the time to work together, t1 is the time it takes one person, and t2 is the time it takes the other person
Plug in the values we know:
= 
+ 
= 
+ 
= 
20 = 6tb
3.33 = tb
So, it would take them 3.33 hours when working together.
I hope I’m not too late but (2,2)
Answer:
yo i only got number 4 for you but here it goes.......: 0.70x+18y-5
Step-by-step explanation:
(0.75x - 12y) + (-5 + 6y - 0.5x)
regroup to the variables : (0.70x-0.5x) + (12y+ 6y-5)
put it together: (0.70x)+(18y-5)
you cant add unlike terms so you remove the parenthesies and your done.
If the rounding is to the nearest ten, then the greatest one
is 67,404 and the smallest one is 67,395 .
If the rounding is to the nearest hundred, then the greatest one
is 67,449 and the smallest one is 67,950 .
