Sam’s brother is 7 years older than Sam . His mother is 4 less than 3 times Sam’s age . Their combined age is 63 . How old is Sa
iren [92.7K]

Answer:

Sam is 12, sam's brother is 19, and sam's mom is 32.

Step-by-step explanation:

First the equation you need to use is S+7+S+3S-4=63(the variable s represents Sam), you combine the like terms which then equals 5S+3=63, then you use inverse operations. Subtract 3 on both sides, 5S=60, then you divide on both sides which equals S equals 12. Then you just plug in the number, S is Sam which means Sam's 12. Then 12+7 which is 19, Sam's brother. Then 3 times 12 minus 4 is 32. And if you check to make sure, 12+19+32 does equal 63.

shepuryov [24]
We have that
<span>n (n-1) -4

for n=1
a1=1*(1-1)-4------> a1=-4

for n=2
</span>a2=2*(2-1)-4------> a2=-2

for n=3
a3=3*(3-1)-4------> a3=2

for n=4
a4=4*(4-1)-4------> a4=8

the answer is
-4,-2, 2, 8

He has a 1/6 chance.
if there are two of 1-6 tiles each in separate bags, he has a chance (total) of 2/12 of getting a 2 and a . simplify the 2/12 to 1/6 and that is your answer.
