Suppose BD bisects ABC. If m ABD = 12x+24 and m DBC = 20x +16 what is m ABC?
Answer:
The measure of ABC is 72
Step-by-step explanation:
if the angle ABC is bisected, it means that the two angles ABD and DBC are equal;
Thus;
12x + 24 = 20x + 16
20x -12x = 24-16
8x = 8
x = 1
The measure of angle ABC is the sum of the two angles
ABC = 12x + 24 + 20x + 16
ABC = 32x + 40
Substitute x = 1
ABC = 32(1) + 40
ABC = 72 degrees

19 points Solve for c. 5/4c+12=2
Answer:
C= -8
Step-by-step explanation:
I used a calculator
Answer:
c=-8
Step-by-step explanation:
[tex]\frac{5}{4}c[/tex] + 12 = 2
1.25c + 12 = 2 ( change 5/4 to a decimal for easy understading)
1.25c + 12 - 12 = 2 - 12 ( isolate the variable rememebr whatever you do to the right do it to the left )
1.25c = -10
1.25c / 1.25 = -10 / 1.25 (divide both sides by 1.25 )
c = -8

Find the term named in the problem.
-21, - 13, -5, 3, ...
Find a23
a(n) = a(1) + ( n - 1 ) × d
a(23) = -21 + ( 23 - 1 ) × 8
a(23) = -21 + ( 22 ) × 8
a(23) = -21 + 176
a(23) = 155

Given h(x) = -5x + 3, find h(5).
6(8-2x)=4x what is the answer to this equation?
Answer:
x=3
Step-by-step explanation:
6(8−2x)=4x
Step 1: Simplify both sides of the equation.
6(8−2x)=4x
(6)(8)+(6)(−2x)=4x(Distribute)
48+−12x=4x
−12x+48=4x
Step 2: Subtract 4x from both sides.
−12x+48−4x=4x−4x
−16x+48=0
Step 3: Subtract 48 from both sides.
−16x+48−48=0−48
−16x=−48
Step 4: Divide both sides by -16.
−16x/−16=−48/−16
