I just need help starting off this question!! If I subtract 2 from my grandfather’s age, the result is divisible by 7. If I subtract 3 from my grandfather’s age, the result is divisible by 5. If I subtract 5 from my grandfather’s age, the result is divisible by 11. How old is my grandfather?

Let your grandfather's age be x, then

for some integers: p, q and r.

Solving for x in the 3 equations we have:

From eqtn (4), possible values of x: 9, 16, 23, 30, 37, 44, 51, 58, 65, 72, 79, 86, 93, 100

From eqtn (5), possible values of x: 8, 13, 18, 23, 28, 33, 38, 43, 48, 53, 58, 63, 68, 73, 78, 83, 88, 93, 98

From eqtn (6), possible values of x: 16, 27, 38, 49, 60, 71, 82, 93, 104

Notice that the only number that appeared in all three is 93.

Therefore, your grandfather's age is 93 years old.

824 =20+?+4 how do you work this out

The answer is 800

20+4=24

824-24=800

800+20+4=824

20+4=24

824-24=800

800+20+4=824

It is 800 just add 20+4 then subtract 824 to that... so that makes it 800 so 824 =20+800+4

Write an expression to describe the sequence below. Use n to represent the position of a term in the sequence, where n = 1 for the first term. 9, 10, 11, 12, ...

Answer:

Step-by-step explanation:

The Given sequence is 9, 10, 11, 12

We need to find the expression to describe the sequence.

Let be the term of the sequence.

Let n represent the position of the term.

Let a be the first term in the sequence.

and d be the common difference between the sequence

Hence the expression to find the above sequence is given below;

when n=1 d= 1 a = 9

when n=2 d= 1 a = 9

when n=3 d= 1 a = 9

when n=3 d= 1 a = 9

Hence the expression is
