15% = 0.15
234.00 x 0.15 = 35.10
234.00 - 35.10 = 198.90
The camera will cost $198.90 after the discount.
Answer:
m<FAB = 75°
m<BAC = 105°
Step-by-step explanation:
First, find the value of x.
(13x - 3)° = (3x + 2)° + 55° (exterior angle theorem of a ∆)
Solve for x
13x - 3 = 3x + 2 + 55
13x - 3 = 3x + 57
Collect like terms
13x - 3x = 57 + 3
10x = 60
Divide both sides by 10
x = 6
✔️m<FAB = 13x - 3
Plug in the value of x
m<FAB = 13(6) - 3 = 78 - 3
m<FAB = 75°
✔️m<BAC = 180 - m<FAB (angles on a straight line/supplementary angles)
m<BAC = 180 - 75 (substitution)
m<BAC = 105°
For -4+2, plot -4, then move to the right 2 spaces. You should land on -2.
For -4+(-2), plot -4 then move the left 2 spaces. You should land on -6.
3t-2+t=4-7t
4t-2=4-7t
-6=-11t
6/11=t
