10. 25% of 40 or 0.25 times 40 gives you 10.
also 25% = 1/4
so 1/4 x 40 = 10
1. ab= 6 x 3 = 18 1) = 18
2. c + 4 = 2 + 4 = 6 2) = 6
3. a/b = 6/3 = 2 3) = 2
4. a - b - 6 - 3 = 3 4) = 3
5. 2c = 2(2) = 4 5) = 4
6. b/3 = 3/3 = 1 6) = 1
7. a - 1 = 6 - 1 = 5 7) = 5
8. 6 + c= 6 + 2 = 8 8) = 8
Step-by-step explanation:
1. Use exterior angles (each adds up to 360) to find interior angles
2. Add this together
3.Take it away from 360
Z = 114 + 2p
p = 46
Plug in 46 for 'p' in the first equation.
z = 114 + 2p
z = 114 + 2(46)
Multiply:
z = 114 + 92
Add:
z = 206
So the Zigzag river is 206 miles long.
(-11,-3) (-6,7)
7+3/-6+11= 10/-5
Slope is -2
