Answer:

x = 22,  y = 22/7

Step-by-step explanation:

solve for y using first equation:

-2 + 3y = 20

3y = 22

y = 22/7

substitute 22/7 into second equation:

7y = x

7(22/7) = x

x = 22

Darina [25.2K]

Answer:

30% probability that it is either red or yellow

Step-by-step explanation:

We have that:

10% of the candies are green

10% of the candies are red

20% of the candies are yellow

20% of the candies are blue

20% of the candies are orange.

The rest is brown. The percentage of brown candies is not important to this problem.

If you pick a candy at random, what is the probability that it is either red or yellow?

10% are red

20% are yellow

10 + 20 = 30%

30% probability that it is either red or yellow

labwork [276]

\large{\dag\:{\underline{\underline{\frak{\pmb{\red{Answer:-}}}}}}}

  • Cricket = 55%
  • Football = 30%
  • Other games = Remaining (?)

So, the percent of people who like <u>other games</u> equals:

= 100 – (55 + 30)

= 100 – 85

= 15%

<u>If </u><u>the </u><u>total </u><u>no.</u><u> </u><u>of.</u><u> </u><u>people</u><u> </u><u>is </u><u>6</u><u>0</u><u>,</u><u>0</u><u>0</u><u>,</u><u>0</u><u>0</u><u>0</u>:

★ Cricket

= 60,00,000 × 55/100

= 33,00,000

★ Football

= 60,00,000 × 30/100

= 18,00,000

★ Other sports

= 60,00,000 × 15/100

= 9,00,000

The angle by which AB turns clockwise about point B to coincide with BC is ? degrees. If from point B, a point E is drawn direct
dedylja [7]

Answer:

Step-by-step explanation:

We have the statement AB turns clockwise to coincide with BC.

= ABD + DBC

= 33.3° + 30.6°  

= 63.9°

Now we have the statement a point E is drawn directly opposite point C. B, E, and C are on the same straight line

EBC is a straight line, so sum of angles =180°

ABE + ABD + DBC = 180°

ABE + 33.3° + 30.6° = 180°

ABE + 63.9° = 180°

ABE = 180 - 63.1

ABE = 116.9° ....
