How do you write 5 plus 7n in words form?
5 plus the product of 7 and n.
How do you solve -7n-8 plus 6 equals 13-2?
-7n - 8 + 6 = 13 - 2 Add 2 to each side: -7n - 8 + 6 + 2 = 13 simplify: -7n = 13 n = -13/7 = -16/7
What is the perimeter of 7n plus 2 plus 6 plus 5n plus 7n plus 3n equals?
22n + 2.
7n plus 3 equals 59 what is n?
7n + 3 = 59 7n = 56 Subtract 3 from BOTH sides n = 8 Divide by 7 on BOTH sides to isolate n
What is the answer for 6 times a number plus 7 times the number?
6n + 7n = 13n
What is 8n plus 7 minus n minus 98?
8n + 7 - n - 98 = 7n - 91
What is the answer to 5m plus 7n equals 6.4 2-7n equals 6?
2 - 7n = 6therefore 7n = 2 - 6 = -4 and so n = -4/7 Then 5m + 7n = 6.4 becomes 5m - 4 = 6.4 so that 5m = 10.4 and then m = 10.4/5 = 2.08
How do you write 6 times a number plus 7 times the number?
6n + 7n (= 13n)
What is the equation 7n equals 7?
7n = 7 divide by 7 on both sides n = 7
What is the value of n in this equation 7n-11 n equals 3n plus 9?
7n - 11n = 3n + 9 Collecting all the terms with n on the left, (7-11-3)n = 9 -7n = 9 Divide both sides by -7 to give n = -9/7
