Answer:
Step-by-step explanation:
<u>27.</u> the sum of 2 complementary angles=90
8x-17+5x-10=90
13x=90+27
13x=117 <u>x=9 </u>
<u>28. </u> the sum of supplementary angles=180
17x-12+3x-48=180
20x=180+60
20x=240
<u>x=120</u>
Answer:
Step-by-step explanation:
Take the beginning number and add or subtract each transaction to get a new balance. For example,
349.45
- 23.42 = 326.03
- 14.95 = 311.08
+ 276.50 = 587.58
- 219.93 = 367.65
- 76.84 = 290.81
Multiply both sides by b
a=cb
divide both sides by c
a/c=b
b=a/c
