Answer:

Step-by-step explanation:

Alright, lets get started.

Arithmetic sequence is when a certain number is added in each term to get the next term of sequence.

The first term is given as -20 in option B

When we add -7 in it, we will get -27

When we add -7 in -27, we will get -34

When we add -7 in -34, we will get -41

When we add -7 in -41, we will get -48

It means this is a arithmetic sequence with common differnce -7.

hence the sequence is -20, -27, -34, -41, -48   :   Answer

Hope it will help :)

Please help me find x using pythagorean theorem
astra-53 [7]

a2+b2=c2

a=x

b=24

c=26

a2+24 squared=26 squared

a2+576=676

-576 -576

a2=100

Then, square root both sides.

It should be a/x=10

Answer:

Step-by-step explanation:

The correct question is

Zena needs a salesperson. Salesperson A is offering his services for an initial $50 in addition to $5 per hour. salesperson B is offering her services for an initial $40 in addition to $7 per hour. When will the two coaches charge the same amount of money?

Let

x ----> the number of hours

y ----> the total charge

we know that

Salesperson A

------> equation A

Salesperson B

------> equation B

To find out when the two coaches charge the same amount of money, equate equation A and equation B and solve for x

7x+40=5x+50

7x-5x=50-40

2x=10

<h2>x=5 hours i think just im not sure but i tried</h2>

Solve the system by substitution.<br> -8x - y = 30<br> -2y = x
masya89 [10]

Answer:

Solution:  (-4, 2),   x= -4 and  y =2

Step-by-step explanation:

-8x - y = 30

-2y = x

Substitute for x

-8*(-2y)   - y = 30

16y  - y = 30

15y = 30

y = 30/15 = 2

Then  x = -2y = -2*(2) = -4

Solution:  (-4, 2),   x= -4 and  y =2
