Answer:
7 and 6
Because in math, a coefficient is a number used to multiply a variable. Here, the variable is M and R therefore the coefficient is 7 and 6.
You subtract 15 from both sides to turn the equation into y = 3x - 15.
BD = BC + CD
7x - 10 = (4x - 29) + (5x - 9)
7x - 10 = 9x - 38
2x = 28
Ans: x = 14
BC = 4x - 29
= 4(14) - 29
= 27
Ans: BC = 27
CD = 5x - 9
= 5(14) - 9
= 61
Ans: CD = 61
BD = 61 + 27
= 88
Ans: BD = 88
