Answer:

r=3

Step-by-step explanation:

Simplify the expression

16-2r=3r+1

isolate r by adding 2r to both sides

16=5r+1

isolate the numbers by subtracting 1 from both sides

15=5r

divide both sides by 5 to completely isolate r

r=3

Answer:

r=3

Step-by-step explanation:

16 - 2r = -3r + 6r +1

Combine like terms

16-2r = 3r +1

Add 2r to each side

16-2r+2r = 3r+2r +1

16 =5r+1

Subtract 1 from each side

16-1 = 5r+1-1

15 = 5r

Divide by 5 on each side

15/5 = 5r/5

3 =r

QveST [7]

Answer:

6.7kg - 2.6kg = 4.1kg

Step-by-step explanation:

6 7/10 is equal to 6.7. If we have 6.7kg of pumpkins, but we can't use 2.6kg, then we subtract to find the amount that we can use.

During a certain day, a worker made 81 parts. He usually does 45 parts per day. What was the percent by which he increased the n

Lana71 [14]

Answer:

The answer is 80%.

Step-by-step explanation:

During a certain day, a worker made 81 parts.

He usually does 45 parts per day.

Number of extra parts made = $81-45=36$

The percent by which he increased the number of parts he usually makes can be given as = $\frac{36}{45}\times100$ = 80%

Therefore, on that day, the percent increased by 80%.
