Step-by-step explanation:

★ $\underline{\large\sf\orange{AnsWer:-}}$

The first question of the poll is concerned about the access of children and adolescents to a computer. Parents had

to check one of 5 response options. Results show that 0.87% of children don’t have access a computer, 68.47% have

only one computer in the household, and usually they have to share it with their siblings or parents, 30.12% have

their own computer and 0.52% have more than one computer in the household.The second question refers to the programme of the children to the computer. Results show that 35.17% of

parents are negotiating with their children an access programme to a computer, while 34.34% of parents impose arigorous programme and 30.47% of children may access the computer anytime they want. Other studies conducted by Stanger and Gridina (1999, apud Subrahmanyam et. al, 2001:9) report that children between 2 and 17 years spend approximately 1h and 37 min a day on computers, including video games.

The next question refers to the purpose the computer is especially used. The computer is mostly used for playing

games (36.28%), rather than for Internet access (22.88%), social networks (14.44%) or homework (26.30%). Another question of the poll asked parents about their opinion on the ways of supervising their children’s activities at the computer.

Answer 2

Answer:

$\frac{x + 6}{4} + \frac{x - 3}{5} = 5x - 4 \\ \\ = > \frac{5(x + 6) + 4(x - 3)}{20} = 5x - 4 \\ \\ = > \frac{5x + 30 + 4x - 12}{20} = 5x - 4 \\ \\ = > \frac{9x + 18}{20} = 5x - 4 \\ \\ = > 20(5x - 4) = 9x + 18 \\ \\ = > 100x - 80 = 9x + 18 \\ \\ = > 100x - 9x = 18 + 80 \\ \\ = > 91x = 98 \\ \\ = > x = \frac{98}{91} \\ \\ = > x = 1.076$

hope this much helps uh ❣️
