Answer:

Step-by-step explanation: as you see the 45 went down by 10, going to 45 to 35 you should do the same in all sides. so 27 minus 10 is 17

Answer:

3 / 5

Step-by-step explanation:

Favourable outcomes -> 2, 4, 5, 6, 8, 10, 12, 14, 15, 16, 18, 20

Number of favourable outcomes = 12

Total number of possible outcomes = 20

P (multiple of 5 or 2) = Number of favourable outcomes / Total number of

possible outcomes

= 12 / 20

= 3 / 5

Hope it helps :)

Help and explain please! 2x+3y=12 Solve for y.

kenny6666 [7]

your question: 

Help and explain please!

Help and explain please! 2x+3y=12

Help and explain please! 2x+3y=12Solve for y.

answer: 

2x + 3y = 12

so basically we want to get y by its self.

first were going to get y on the left side and everything else on the right. in order to do that we have to subtract 2x from the left and do the same on the other side.

2x + 3y=12

-2x. -2x

3y = 12 -2x

then we divide everything by 3 on the other side to get y by its self.

3y = 12-2x

--- ----. ----

3. 3. 3

y= 4 -2/3x

should be your answer.

Hope this helps, have a great day!

7. In triangle ABC, side AB is 2 cm shorter than side

Mamont248 [21]

Answer:

AC = 21, AB = 19, and BC = 22

Step-by-step explanation:

If x is the length of AC, then:

AB = x − 2

BC = x + 1

The perimeter is the sum of all three sides:

62 = x + x − 2 + x + 1

62 = 3x − 1

63 = 3x

x = 21

Therefore:

AC = 21, AB = 19, and BC = 22
