Answer:
16
Step-by-step explanation:
7x-5+4x-7+x=180
11x-12+x= 180
12x-12=180
+12 = +12
12x = 192
/ 12 / 12
= 16
The answer for b is 18 ; 2×6 +3×2
then for c. 24; 2×6×2

Answer:
855.8
Step-by-step explanation:
hundreds tens ones . tenths hundredths thousandths
8 5 5 . 7 8 8
We are rounding to the nearest tenth, so we look at the next number which is 8. 8>= 5 so we will round the 7 up
855.788 rounds to 855.8
If b=2 and c=3, then
a= √(3²-2²) = √(9-4) = √5
If a=3 and c=6, then
b= √(6²-2²) = √(36-9) = √27 = 3√3
If a=4 and b=6, then
c= √(4²+6²) = √(16+36) = √52 = 2√13
