Pachacha [2.7K]

Answer:

<em>4 is the unit's digit of the 20th number.</em>

Step-by-step explanation:

Let us try to find out a pattern for the unit's digit of the terms.

1st term is 1, so unit's digit of 1st term is 1.

2nd term $1^{2} + 3 = 4$ so unit's digit is 4.

3rd term $4^{2} + 3 = 19$ so unit's digit is 9.

4th term $19^{2} + 3 = 364$ so unit's digit is 4.

5th term's unit digit: Square of unit's digit of 4th term + 3

$4^{2} + 3 = 19$ i.e. 9.

We can see that the pattern is

3rd, 5th, 7th ...... terms have 9 as the unit's digit.

2nd, 4th, 6th.... terms have 4 as the unit's digit.

So, 20th term will have 4 as the unit's digit.

If $\frac{9u-11}{2} = \frac{19u+11}{3}$, what is the value of $u$? Ps i need the answer

klio [65]

I believe you are referring to this equation: (9u-11)/2 = (19u +11)/3. To solve this step-by-step, first, multiply each side by 6 which is the least common denominator of 2 and 3. This then results to: 27u - 33 = 38u + 22. Second, combine like terms on one side such that: 11u = -55. Finally, the value for u is calculated to be -5.

Keith bought 8 new baseball trading cards to add to his collection. The next day his dog ate half of his collection. There are n

Nat2105 [25]

Answer:

52 cards

Step-by-step explanation:

call the amount he started with " x "

then he bought 8 cards

so the new equation is

x+8

then he lost half of his cards

so now the equation is

(x + 8 )/2

that amount to 30 cards as per what is given in the problem

so now the equation is

( x + 8 )/2 = 30

solve using inverse operations and simplifying

( x + 8 )/2 = 30

*2 *2

x + 8 = 60

-8 -8

x = 52
