Um I’m so confused , help ?

Answer:

A). 15

B). -1.2

Step-by-step explanation:

A). [10(x+3)]-20 = 160

10x+30-20 = 160

10x+10 = 160

10x = 160-10

10x = 150

x = 150/10

x = 15

B). 5{[4(8+(5x))]-9} = 85

5(32+20x+9) = 85

5(32+9+20x) = 85

5(41+20x) = 85

205+100x = 85

100x = 85-205

100x = -120

100x/100 = -120/100

x = -1.2

open the bracket, you will have

5x-2x+13=40

collect like terms

5x-2x=40-13

3x=27

divide both side by 3

3x/3=27/3

x=9

Answer: 9

Step-by-step explanation:

5x-(2x-13)=40

Open bracket by -1

5x-2x+13. = 40

3x. = 40-13

3x. =. 27

Divide both sides by 3

x. = 27/3.

x. = 9

Answer:

too blury I can't see can you make another?

Answer:

Number of pencils in stock = 1200

Average number of pencils sold by the manager per day = 24

Number of pencils that would be sold before reordering = 1200 - 500

                                                                                        = 700

Then

The number of days after which the manager will reorder = 700/24

                                                                                            = 29.16

So the manager has to reorder after about 30 days. Since the answer comes in fraction of more than 29 days, so it has to be 30 days. I hope the procedure is clear for your understanding.

Just to be clear, this answer is not mine, but I remember seeing this question so I just copied someones' answer. Still, you might find this helpful.

Answer:

x = 1.58 and y = 0.105

Step-by-step explanation:

Given equations are :

5x+y =8 ...(1)

x+4y=2 ...(2)

Multiply equation (2) by 5.

5x+20y=10 ..(3)

Subtract equation (1) from (3).

5x+20y-(5x+y) = 10-8

5x+20y-5x-y = 2

19y = 2

y = 0.105

Put the value of y in equation (2).

x+4(0.105)=2

x = 2-0.42

x = 1.58

Hence, the values of x and y are 1.58 and 0.105.

What are the effects on the graph of y=x^2 caused by the values of a, h, and k in the function y=a(x-h)^2+k

Answer:

a) f(10) = 18

b) g-¹(x) = 5x-5

c) 3((3(x-4))

= 3((3x-12)-4))

= 3(3x-16)

= 9x-48

The value of f(10) = 18, g'(x) = 1/5 and ff(x) = 9x - 48​

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.

Given that, The functions f and g are such that f(x) = 3(x – 4) and

g(x) = x/5+1

a) f(10) = 3(10-4)

= 3(6)

= 18

b) g'(x) = d/dx(x/5+1)

= 1/5d/dx(x) = 1/5

c) ff(x) =

= 3((3(x-4))

= 3((3x-12)-4))

= 3(3x-16)

= 9x-48

Hence, The value of f(10) = 18, g'(x) = 1/5 and ff(x) = 9x - 48​
