It'd be helpful if you posted a picture of the bar model so we can actually help you lol
68 + (x / 54) = 72 68 + (x / 54) • 54 = 72 • 54 68 + x = 72 • 54 68 + x = 3,888 68 + x - 68 = 3,888 - 68 x = 3,888 - 68 x = 3,820 I'm pretty sure this is right. Good luck!
Answer:
37
Step-by-step explanation:
35 is 1×35/ 5×7
36 is 1×36/ 2×18/ 3×12/ 4×9/ 6×6/ 2²×3²
37 is 1×37
38 is 1×38/ 2×19
Answer:
73 nails
Step-by-step explanation:
Number of 1 inch = 255
Boxes of 2 - inch = 5
Each box of 2 _inch has equal amount of nails
Total number of nails = 620
Number of nails in each box of 2_inch nails:
Let Number of nails in each box = b
Number of 1_inch + 5 * number of 2_inch = 620
255 + 5b = 620
5b = 620 - 255
5b = 365
5b / 5 = 365 / 5
b = 73
Hence, there are 73 nails in each box of 2_inch nails
Since the triangles are the same, just flipped that means that all angles and segments are the same as well
I'm not sure if that's the "correct" way to prove it but that's why they're equal
