Mexico won the mexican american war
Answer:
x-7
Step-by-step explanation:
7x - 18 = 10x + 3
Subtract 7x from each side
7x-7x - 18 = 10x-7x + 3
-18 = 3x+3
Subtract 3 from each side
-18-3 = 3x
-21 = 3x
Divide by 3
-21/3 =3x/3
-7=x
Answer:
16
Step-by-step explanation:
Lets assume x is Elgas' age
And y is Alvins age
we know that alvin is 11 years younger than Elga which means,
x=y+11
and the sum of their age is 43
x+y=43
solve it and you get 16
Probability of picking a yellow marble = no of yellow marbles/total number of mables = 6/(4 + 12 + 6) = 6/22 = 3/11
Probability of picking a blue marble = 12/22 = 6/11
Probability of picking a yellow marble and a blue marble = 3/11 x 6/11 = 18/121
