Answer: 9*10 + 9*11 + 9*12

Step-by-step explanation:

The distributive property of multiplication states that when a number is multiplied by the sum of several numbers, the first number can be distributed to all of those numbers and multiplied by each of them separately.

9(10 + 11 + 12) = 9*10 + 9*11 + 9*12

Answer:

90 + 99 + 108

Step-by-step explanation:

The 3 number being added should be multiplied by 9.

10 x 9 = 90.

11 x 9 = 99.

12 x 9 = 108.

Therefore, 90 + 99 + 108.

Which sequence is generated by the function f(n + 1) = f(n) – 2 for f(1) = 10?
PSYCHO15rus [73]

Answer: The sequence generated is 10, 8, 6, 4, 2, ...

This sequence is arithmetic with starting term 10 and common difference -2. This means we add -2 to each term to get the next one (same as subtracting 2 from each term). This common difference is directly connected to the -2 from the recursive rule f(n+1) = f(n)-2

Whatever the nth term f(n) is, we subtract off 2 to get f(n)-2 to get the f(n+1) term, which is right after the nth term.

Answer:

UMBC scored 10,14 and 12 one - point free throws, two point baskets and three point baskets respectively.

Step-by-step explanation:

Let's start defining the variables.

X : ''Number of 1 - point free throws''

Y : ''Number of 2 - point baskets''

Z : ''Number of 3 - point baskets''

UMBC scored a total of 74 points. Therefore,

X.1+Y.2+Z.3=74 (I)

Where X.1 represents the total points from 1 - point free throws.

Where Y.2 represents the total points from 2 - point baskets.

And finally Z.3 represents the total points from 3 - point baskets.

Reading the exercise, we can write two more equations :

Y=Z+2\\Z=X+2

Let's write Y and X in terms of Z

Y=Z+2 (II)

Z=X+2 ⇒ X=Z-2 (III)

Replacing (II) and (III) in (I) :

(Z-2).1+(Z+2).2+Z.3=74

Z-2+2Z+4+3Z=74

6Z+2=74\\6Z=72\\Z=12

We find that the variable Z is 12. Replacing this value in (II) and (III) ⇒

Y=12+2=14\\Y=14

X=12-2=10\\X=10

Finally, UMBC scored 10 baskets from 1 - point free throws,14 baskets from of 2 - point and 12 baskets of 3 - point.

We can verify by replacing X = 10 , Y = 14 and Z = 12 in equation (I) :

10.1+14.2+12.3=74\\10+28+36=74\\74=74

a furniture rental store charges a down payment of $100 and $72.50 per month for a table. Hilde paid $535 to rent the table. Sol
elixir [45]

We are given : In a furniture rental store a down payment  = $100.

Monthly charge of the table = $72.50 per month.

Total amount to be paid for the table = $535.

Let us assume number of months be n for which Hilde rented the table.

We are given equation also 72.50n + 100 = 535.

We need to solve the equation for n.

72.50n + 100 = 535.

<em>Subtracting 100 from both sides, we get </em>

72.50n + 100-100 = 535-100

72.50n = 435

<em>Dividing both sides by 72.50, we get </em>

72.50n/72.50 = 435/72.50

n = 6.

<h3>Therefore, for 6 months Hilde rented the table.</h3>
