How many solutions does the equation have? f + 7 = f - 3

Answers

Answer:

there is no solution

Step-by-step explanation:

Answer:

no solutions

Step-by-step explanation:

Given

f + 7 = f - 3

Given any value for f then f + 7 ≠ f - 3

Hence the equation has no solution

Through solving we obtain

f + 7 = f - 3 ( subtract f from both sides )

0 + 7 = - 3

7 = - 3 ← not possible, thus no solution

three rock climbers started a climb with each person carrying 7.8 kilograms of climbing equipment. A fourth climber with no equipment joined the group The group divided the total weight of climbing equipment equally among the four climbers

Answers

Answer:

Each carried 1.95 kg weight

Step-by-step explanation:

Given :Three rock climbers started a climb with each person carrying 7.8 kilograms of climbing equipment.

A fourth climber with no equipment joined the group The group divided the total weight of climbing equipment equally among the four climbers

To Find : How much did each carry ?

Solution :

Each person out of three is carrying weight = 7.8 kg

So, Total weight carried by 3 climbers = 7.8 * 3 =23.4

Now A fourth climber with no equipment joined the group

Total weight is divided among 4

So, weight carried by each climber = (7.8)/(4)=1.95

Hence each carried 1.95 kg weight

The correct answer is:

Each climber is carrying 5.85 kg.

Explanation:

3 of the 4 climbers is carrying 7.8 kg each; this is 3(7.8) = 23.4 kg.

Dividing this equally among the 4 climbers, we have 23.4/4 = 5.85 kg each.
