These are linear equations that can be solved simultaneously;
5m+3n=41
3m-6n=9   (multiplying the first equation by 3 and the second by 5)

15m+9n=123
15m-30n= 45 (subtracting the two equations)
         39n = 78
             n = 2, 
and for m, 3m = 9+6(2)
                        = 21
                     m = 7
Therefore, n=2 and m=7

2a+b=15.7 what’s the possible values of b
Fiesta28 [93]

Answer:

b = 15.7 -2a

Step-by-step explanation:

You are asking us to solve for b

2a +b = 15.7

Subtract 2a from each side

2a-2a+b = 15.7 -2a

b = 15.7 -2a

Jamal states that ax + b = a(x + c), given a, b, and c are not equal to 0. What must be the value of c for Jamal's statement to
Anna35 [415]

ANSWER

For Jamal statement to be true,

c = \frac{b}{a}

EXPLANATION

The given statement is:

ax + b = a(x + c)

We expand the left hand side to obtain,

ax + b = ax + ac

Subtract ax from from both sides of the equation.

b=ac

We know that, a≠0 , so we can divide through by 'a'.

\frac{b}{a}  = c
