Help me pleaseeeeeeeee
topjm [15]

Answer:

x = 6, y = 3

Step-by-step explanation:

Let Sally's age be x and Tomas's age be y.

Sum of Sally's age plus twice Tomas's age: x + 2y = 12

Difference of Sally's age and Tomas's age: x - y = 3

Multiply the second equation by two and add it to the first equation to get

3x = 18, which means x = 6.

Plug 6 in for x in the second equation to get 6 - y = 3, which means y = 3.

The length of a rectangle is twice it’s width. If the perimeter is 60 feet, find the dimensions.
Irina-Kira [14]
Perimeter = length * 2 + width * 2. x = width. 2x = length. perimeter = 2(x) + 2(2x). perimeter = 2x + 4x. 60 (perimeter) = 6x. divide both sides by six. x = 10. width = 10. length is 2(width), so length is 20.

Picking a number that is divisible by 5 from a jar with papers labeled from 1 to 12
kogti [31]
Total number of possible outcomes:12
Number of favourable outcomes:2( since only two numbers divisible by 5 in that range are 5 and 10)
The possibility that you'll pick a number divisible by 5 is 2/12 or 1/6
Hope that's what you're looking for since you didn't specify.
