Answer:
1. 175
2. 28
Step-by-step explanation:
If you're converting from another base, just multiply each digit, then add up the numbers:
ones digit × 8^0,
tens digit × 8^1
hundreds × 8^2

The second problem gives you a new operation. Follow the rule by squaring the first number and taking away the first×second. Do the parenthesis first!

10 • 4 = _ • 5
10•4=40
40/5=8
Answer:
x = 3
Step-by-step explanation:
7x - 9 + 3x = 2x + 18 - x
10x - 9 = x + 18
10x - x = 18 + 9
9x = 27
x = 3
A straight angle is equal to 180 degrees. 180-80=100. 100-60=40. so y=40. vertical angles are congruent so x=40 degrees.
8x + 3c = 2200
11xc= 2200
2200÷11
200
200xc
