So set up the equations
q-12=d
25q+10d=1105
plug in q-12 as d in the second equation:
25q+10q-120=1105, then simplify:
35q=1225
q=35
since there's 12 fewer dimes, we know that there's 23 dimes and 35 quarters.
Answer:
Step-by-step explanation:
Use the slope formula:
*Slope is rise over run, hence y (vertical) over x (horizontal)*
Notice that the one in the denominator is positive. This is because the x value for point M is negative one and you're subtracting it from the four. When there are two negative like this, it turns into a positive (+).

Answer:
option D is true
Step-by-step explanation:
Given expression is
3x^2 -11(2y+1) + 4
A) 11 is not a constant , because 11 is multiplied with 2y+1
B) 3 in the first term is not a exponent. 3 is the coefficient of x^2
C) 4 in the third term is not a factor, 4 is a constant
D) 2 in the second term is the coefficient of y. so 2 is a coefficient. That is true
