Solve for x and y
x=5
x+y=12

x = 5, y = 7

Step-by-step explanation:

We are given the value of x, that is x = 5

Substitute x = 5 into the other equation and solve for y

5 + y = 12 ( subtract 5 from both sides )

y = 7

Step-by-step explanation:

hello : x=5

         x+y=12  

so  :  5+y =12

y=7

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.
