answer:
y = 114° and x = 120°
step-by-step explanation:
part A:
- second inner angle: (180°-87°) = 93°
- third inner angle: (180°-30°) = 150°
- fourth, beside y angle: 360° - 150° - 93° - 51° = 66°
- then y = 180° - 66° = 114°
part B:
- there are 6 sides, so inner angle: (6-2)*180 = 720°
- 160° + 123° + 107° + 90° + x + x = 720°
Answer:
Cost price = 200
Profit = 230-200 = 30
Step-by-step explanation:
x + 15/100x = 230
x + 3/20x = 230
20x + 3x = 4600
23x = 4600
x = 200
Um if that is the whole number it would be ^
if its .9245 it would be .92
A.4d+$13.00-$6.00=$13.20 is your answer.
The reason for this is :
Step One : Start with what you know
($13.00-$6.00)
Then make a full equation based on what you need to find out.($7.00+4d)/4=(13.20)/4
Start simplifying.
(1.75+d)-1.75=(3.3)-1.75
Continue to simplify for your answer.
d=1.55
1.55 is the answer.
(A is your answer.)
