9m - 14n
1/2*(n*5) = n*2.5
5 plus the product of 7 and n.
8¾
4 more than the product of 2 and n
Gather the m's and n's by rewriting it. 7m - 11n - n + 5m 7m + 5m -11n - n (7m + 5m) + (-11n - n) 12m - 12n ■
5m-13n-n+4m= (5+4)m+(-13-1)n= 9m-14n
9m - 14n
5m+2n, n-3m, 7-3n (5m+2n)+(n-3m)+(7-3n)=2m+7
If we are to find the product of 5 and m and n/2 (which is half of n), we have: 5 times m times n/2 = 5 x m x n/2 = 5mn/2
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
The answer depends on what you mean by 11 in(n) a half - which is not an expression that is recognised.
1/2*(n*5) = n*2.5
m+6n
5 plus the product of 7 and n.
