Answer:

Step-by-step explanation:
∠ADC = 112°
∠ADC =6x + 7 + 12x - 3
Equate both:
6x + 7 + 12x - 3 = 112
Solve for x :
6x + 7 + 12x - 3 = 112
Combine like terms:
18x + 4= 112
Take away 4 from both sides:
18x = 108
Divide both sides by 18:
x = 6
Find ∠ADB:
6x + 7 = 6(6) + 7 = 43
Answer: ∠ADB = 43°

MAKE MY ANSWER BRILLINEST PLEASE:)
Step-by-step explanation:
LET:
j = the points that Jessica scored
t = the points that Tina scored
Jessica scored 147 more points than Tina:
j = t + 1497
Together, Bradley and Harner scored 1601 points:
j + t = 1601
by solving the system of equations:
j = t + 147
j + t = 1601
we find
j = 856 points
t = 707 points
Jessica Bradley scored 856 point.
Tina Harner scored 707 points.
There is one answer, -24.
While yes, absolute value does indicate both a positive and negative will work, for every x value there will be only one y value associated with it; if there were more, then it would not meet the criteria to be a function.
