What value makes the two expressions equivalent? 45x + 72y __(5x + 8y)

Mathematics

zimovet [89]3 years ago
3 0

Answer:

9

Step-by-step explanation:

This is because of the distributive property.

The outside number is multiplied by each inside number.

So, if it's 9(5x+8y), then do 9*5x which is 45x and 9*8y which is 72y.

Two miners are trying to push a stationary mine cart filled with gold. Miner A is exerting 25 N while miner B is exerting 20 N.
Oliga [24]

Answer:

b. 45 N

Step-by-step explanation:

The sum of the forces exerted by the two miners = 25 + 20

                                           = 45 N

Since after applying a force of 45 N by the two miners the cart remained stationary, it implies that a resistance force of at least 45 N acts against their push. Thus, the force exerted by the road could be equal to 45 N or greater than 45 N.

Probably, if the sum of the forces applied is 46 N, the cart would move. Which depends on the value of resistance force applied by the road. Thus, the appropriate answer from the given option is B.

Since the force applied on the cart equals the resistance force exerted by the road, the cart would not move.
