The total weight is 170 pounds. | 45 + 2 ( 45 + 10 + c ) + c = 170 |
How many pounds does each clamp weigh? | 45 + 2 ( 45 + 10 + c ) + c = 170 |
170 lbs
=
How many pounds does each clamp weigh? | 45 + 2 ( 45 + 10 + c ) + c = 170 |
Multiply the weight of the plates and clamps since there is one of each on each side. | 45 + 90 + 20 + 2c + c = 170 |
170 lbs
=
How many pounds does each clamp weigh? | 45 + 2 ( 45 + 10 + c ) + c = 170 |
Multiply the weight of the plates and clamps since there is one of each on each side. | 45 + 90 + 20 + 2c + c = 170 |
Combine the weight of the bar and plates. | 155 + 2c + c = 170 |
170 lbs
=
How many pounds does each clamp weigh? | 45 + 2 ( 45 + 10 + c ) + c = 170 |
Multiply the weight of the plates and clamps since there is one of each on each side. | 45 + 90 + 20 + 2c + c = 170 |
Combine the weight of the bar and plates. | 155 + 2c + c = 170 |
Combine the weight of the three clamps, 3c. | 155 + 3c = 170 |
170 lbs
=
How many pounds does each clamp weigh? | 45 + 2 ( 45 + 10 + c ) + c = 170 |
Multiply the weight of the plates and clamps since there is one of each on each side. | 45 + 90 + 20 + 2c + c = 170 |
Combine the weight of the bar and plates. | 155 + 2c + c = 170 |
Combine the weight of the three clamps, 3c. | 155 + 3c = 170 -155 -155 |
Subtract the weight of the plates and bar from the total weight. | 3c = 15 |
15 lbs
=
How many pounds does each clamp weigh? | 45 + 2 ( 45 + 10 + c ) + c = 170 |
Multiply the weight of the plates and clamps since there is one of each on each side. | 45 + 90 + 20 + 2c + c = 170 |
Combine the weight of the bar and plates. | 155 + 2c + c = 170 |
Combine the weight of the three clamps, 3c. | 155 + 3c = 170 -155 -155 |
Subtract the weight of the plates and bar from the total weight. | 3c = 15 3 3 |
Divide the remaining weight by three to find that each clamp weighs five pounds. | C = 5 |
