Step-by-step explanation:
Answer:
8
Step-by-step explanation:
Well 2x=16 is the same as x=8 when you divide by 2. So the dot should be on 8.
Answer:
10
4
Step-by-step explanation:
Purple: This makes two trapezoids. A=(a+b)/2 times h
1st = (4+1)/2 x 1 = 2.5
2nd = (4+1)/2 x 3 = 5/2 x 3 = 2.5x3=7.5
Total = 2.5+7.5=10
Green: if you draw a line down the center, you can divide these into two more manageable triangles. A=1/2bh
1st = 1/2x2x2 = 2
2nd = 1/2x2x2 = 2
Total = 2+2=4
Answer:
416/x = 208
Step-by-step explanation:
the opposite of multiplication is division
so divide both sides by 416
1/x = 208/416
at this point you need to flip both sides
x = 416/208
