1. Seven multiplied by three
7*3 the little star mean times

2. Twice the opposite of eleven= 2x+11
22 less than 3 times the number
3x-22
3x-22=2x+11
3x-2x=11+22
x= 33
So , it would be 2x+11 x is 33

Hope this helps good luck

The sum of a and 46 is equal to k. Let k = 97. Which equation can be used to find the value of a? A. a + 46 = 97 B. a – 97 = 46

lawyer [7]

Sum means to add, so you are adding a and 46 to get k. k is given as 97 so your equation used to solve for a is a + 46 = 97, choice A from above.

I need this one please I don’t understand it

Dovator [93]

Answer:

Hi! your answer should be C. √34

Step-by-step explanation:

a^2+b^2=c^2 (leg^2+leg^2= hypotenuse^2)

5^2+3^2=c^2

25+9=c^2

34=c^2

square root both sides.

√34=c

the hypotenuse is C. √34

Which function describes the arithmetic sequence shown?

Assoli18 [71]

Answer:

The function $a_n=2n-3$ describes the arithmetic sequence.

Step-by-step explanation:

Given the sequence

-1, 1, 3, 5, 7, 9, 11, 13

An arithmetic sequence has a constant difference 'd' is defined by

$a_n=a_1+\left(n-1\right)d$

Compute the differences between all the adjacent terms:

$1-\left(-1\right)=2,\:\quad \:3-1=2,\:\quad \:5-3=2,\:\quad \:7-5=2,\:\quad \:9-7=2,\:\quad \:11-9=2,\:\quad \:13-11=2$

As the difference between all of the adjacent terms is the same and equal to

$d=2$

As the first element is

$a_1=-1$

so the term will be:

$a_n=a_1+\left(n-1\right)d$

$a_n=2\left(n-1\right)-1$

$a_n=2n-3$

So, the function $a_n=2n-3$ describes the arithmetic sequence.
