Mathematics

Step 1. Factor out the common term 2

n - 2 = 2(5n + 2)/2

Step 2. Cancel 2

n - 2 = 5n + 2

Step 3. Subtract n from both sides

-2 = 5n + 2 - n

Step 4. Simplify 5n + 2 - n to 4n + 2

-2 = 4n + 2

Step 5. Subtract 2 from both sides

-2 - 2 = 4n

Step 6. Simplify -2 - 2 to -4

-4 = 4n

Step 7. Divide both sides by 4

-1 = n

Step 8. Switch sides

n = -1

Answer:

n= -1

Step-by-step explanation:

n−2= 10n+4 /2

n+−2=5n+2(Distribute)

n−2=5n+2

Subtract 5n from both sides.

n−2−5n=5n+2−5n

−4n−2=2

Add 2 to both sides.

−4n−2+2=2+2

−4n=4

Divide both sides by -4.

−4n

−4

=

4

−4

n= -1

Estimate the value 9.03 + 19.87 x 3.11 - 4.97
dybincka [34]

Answer:

82

Step-by-step explanation:

For this problem you would first round everything. 9.03 becomes 9, 19.87 becomes 20, 3.11 becomes 3 and 4.97 becomes 5. You then just do the problem. 9 + 20 = 29, multiplied by 3 makes 87, 87 - 5 = 82.

(d) Jim walks three miles in 45 minutes. How long does it take for him to walk 5 miles?​
kramer

Answer:

  • 5 miles = 75 minutes

Step-by-step explanation:

<u>We know that:</u>

  • 3 miles = 45 minutes

<u>Solution:</u>

  • 3 miles = 45 minutes
  • => 1 mile = 45/3 minutes
  • => 5 miles = 45/3 x 5
  • => 5 miles = 15 x 5
  • => 5 miles = 75 minutes

Hence, it takes 75 minutes for Jim to walk 5 miles.
