1) Solve the equation 7x+5 = 7x-3

no solutions

7x + 5 = 7x - 3

5 = -3                  [ subtract 7x from both sides ]

Since we end up with 5 = -3, a clearly false equation, we conclude that the original equation has no solutions.

i hope this helps! :D

empty set

Step-by-step explanation:

Let's solve your equation step-by-step:

7x+5=7x−3

Step 1: Subtract 7x from both sides.

7x+5−7x=7x−3−7x

5=−3

Step 2: Subtract 5 from both sides.

5−5=−3−5

0=−8

So that There is no solution.( empty set .∅)

please make as brilliant.

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
