The second one I believe because it’s basiclalu going up one half everytime to get to one
4/10 x 0.04 = (of means multiply)
0.4 x 0.04 =
0.016
To be a parallogram the 2 angles shown need to equal 180 degrees
so we have: 34 + (4x-2) = 180
now we can solve for x
34 + 4x -2 = 180
simplify the left side by subtracting 2 from 34
32+4x =180
subtract 32 from each side:
4x = 148
divide both sides by 4 to get x
x = 148 / 4
x = 37
The answer is B
25 cuz 18/3=6 and 22+9=31. 31-6=25
2.964 bolts
Because 7.8*.38=2.964
