-8
2(8 + 5) = 2(13) = 26
The answer is -9 because -5 +2a = -13. -5 on both sides looks like this 2a = -18. Divide 2 on both sides because the variable has to be alone. a = -9
Then the number is 3

Five more than twice a number is -13 find the number
Twice the difference between a number and thirteen can be written as 2 (b - 13) Five more than twice the difference between a number and thirteen can be written as 2 (b - 13) + 5. The algebraic expression is 2 (b - 13) + 5.
-8
2(8 + 5) = 2(13) = 26
2n+13
5+2n=13-5 -52n 8n=4Explain the answerFirst, subtracting -5 the both of sides. Next, divided by 2 the both sides.Finally, the n will be equal 4.5 + 2n = -132n =-13 - 5 = -18n = -9
Division. 13/5. 5 goes into 13 twice, so that is our whole number, 2. 13 - 10 = 3. The 1 fifth is put in. 3/5. So our answer is 2 and 3/5 For further clarification, message me on my message board. Thanks!

The element with an atomic number twice that of aluminum (13) is magnesium, which has an atomic number of 12.
Then the number is 3
