Answer:
Step-by-step explanation:
MR=2x-1. First equation
RP=9x+3 second equation
MP=MR+RP third equation
MP= 2x-1+9x+3 first equation plus second equation
MP=11x+2
MP=57
57=11x+2 replaced MP value
57-2=11x
55=11x
55/11=x
X=5
Answer: 1. When you estimate, it is not an exact measurement. 3ft 8 in gets rounded to 4ft and 12 ft 3 in rounds to 12ft. now find the perimeter. P=2l+2w P= 2*12 +2*4 P=32feet
2. 3ft 8in = 3 8/12 or reduced to 3 2/3 12ft 3in = 12 3/12 or reduced to 12 1/4 The fractional part is referring to a fraction of a foot.
3. The perimeter of the room is P=2l+2w or P=2(12 1/4) + 2(3 2/3) p=24 1/2 + 7 1/3 P= 31 5/6 feet
4. The estimate and the actual are very close. They are 1/6 of a foot apart.
5a. Total baseboard 31 5/6ft - 2 1/4 ft = 29 7/12 feet needed.
5b. Take the total and divide it by 8ft = 29 7/12 divided by 8= 3.7 You are not buying a fraction of a board so you would need 4 boards.

Part B:
40 - 40 = 0 overtime hours.
44 - 40 = 4 overtime hours.
48 - 40 = 8 overtime hours.
52 - 40 = 12 overtime hours.

Answer: 13,I
Step-by-step explanation:
set the 3 number is 3/5, x,y
product of them
3 /5 xy = 7:6
xy = 7:6 x 5 /3
Xy = 13
So the two number is 13, 1
Step-by-step explanation: hope this helped, Meow!
Answer:
The value of x is incorrect he should be using 28/21 instead of 21/28
Step-by-step explanation:
tan = opp/adj
tanx = 28/21
The value of x is incorrect he should be using 28/21 instead of 21/28
