Answer:

c<=25

Step-by-step explanation:

-1/5c>=-5

*-1         *-1

1/5<=5

*5      *5

c<=25

lets check

-1/5(25) +1>=-4

-5+1>=-4

-4>=-4

its correct :D

Hey there!

5x - 6y - 3a

= 5(-2) - 6(3) - 3(-4)

= -10 - 18 - 12

= -28 - (-12)

= -28 + 12

= -16

Therefore, your answer is: -16

Good luck on your assignment and enjoy your day!

Answer:

The selling price is $17.40

Step-by-step explanation:

x = selling price

x = 12 + 0.45(12)

x = 12 + 5.4

x = 17.4

The final selling price is $17.40.

Percentages are percents of a whole. This means that 45% = 0.45. You can use this to your advangage when solving these types of equations.

Answer:

$17.40

Step-by-step explanation

Find what 45% of 12 is.

You can do this by multiplying 0.45 by 12 which is 5.4

Then you just add 5.4 to 12 which gives you 17.4  

Answer:

Answer:

the perimeter of the square is 104

Step-by-step explanation:

to find the perimeter of a square we need to use the formula P = 4a

P is perimeter and a is the side of the square

if a is the side and the formula of Area is A = a^2

that means the side of the square is a = 26 because 26 * 26 = 676

now we take 26 and place it in the a spot of the perimeter formula

P = 4 * 26   (P = 104)

can i get brain if this helps and is correct plz and thxs <(^w^)>

Answer:

It should be ben because if it is ben then you would divide 4  1/2 into 1/4

Step-by-step explanation:

he will have 18 peices in total(But thats not what the question is asking)

The answe is Ben/B

Answer:

ben had a 4 1/2 foot-long sandwhich. he cuts the sandwich into a 1/4 foot-long pieces. how many pieces of sandwich does Ben have?

Step-by-step explanation:

this one is correct because the other 3 aren't for division.

Answer:

17)  x=7

18) x= -26

19) x= -8

20) x= 6

Step-by-step explanation:

17) is congruent

18) is supplementary

19) is congruent

20) is congruent

Answer:

Q17. 6x+8=50 (alt angles, u//v)

6x=50-8

=42

x=42÷6

=7

Q18. 80°+x+106°=180° (int angles, u//v)

x+186°=180°

x=180°-186°

=-6

Q19. x+68=60 (vert opp angles)

x=60-68

=-8

Q20. 20x=120°

x=120÷20

=10

Answer:

Slope = -2

Y-intercept = 13

y = -2x + 13

Step-by-step explanation:

(5-3)/(4-5) = 2/-1 = -2

3 = -2(5) + b

3 = -10 + b

b = 13

y = -2x + 13

hopefully this helps !

Answer:

$1.20 in pennies, $3 in nickels

Step-by-step explanation:

(i fell like im wrong :{ )

Answer:

Step-by-step explanation:

See the steps below:

First Method: (By splitting the middle term)

We have to find p and q such that p+q = 20 and

pq = 3×(-7) = -21

Let us looks for the pair of factors of -21 such that their sum is 20 and product is -21.

20 = 21 - 1 and -21 = 3(-7)

∴ 3x² + 20x - 7 = 3x² + 21x - 1x - 7

= 3x(x + 7) -1(x + 7)

= (x + 7)(3x - 1)

Second method: (Using the factor theorem)

Answer: y = -5/4x+5

Because those points are bold. So these are the given points

Answer:

(m+10)(m-9)

Step-by-step explanation:

To factor this equation we want to find two numbers that multiply to -90 but also add/subtract to 1.

Those two numbers are 10 and -9 (10×-9=-90, 10-9=1)

Answer:

[tex](m-9)(m+10)[/tex]

Step-by-step explanation:

When you are given an expression in this format

[tex]ax^2+bx+c[/tex]

You must find two numbers that add up to b while the product is c.

You do trial and error to figure it out for your equation.

[tex]m^2+m-90[/tex]

Hmm... what two numbers add up to 1 and multiplied together equal -90.

Start off with pairs that can equal 90.

45 2

18 5

9 10

Ok, well 45 * 2 does equal 90 but 45 + 2 = 47and 45 + -2 = 43 but there's no way I can make it equal to 1. Next!

18 * 5 equals 90 but 18 + -5 = 13 and 18 + 5 = 23, I can just tell that there's no way I can make this equal to 1.

9 * 10 equals 90, 9 + 10 = 19 but 9 + -10 = -1. Now, that's interesting, We have -1 but we need 1. All we have to do is flip the order. 10 + -9 = 1. And -9 * 10 = -90, PERFECT!

Now use the two numbers and put it in factored form.

[tex](m-9)(m+10)[/tex]

Answer:

equals x cuz x is in definite number

Step-by-step explanation:

Hi there!  

»»————-　★　————-««

I believe your answer is:  

Yes, it is a solution.

»»————-　★　————-««  

Here’s why:  

⸻⸻⸻⸻

I am assuming that 'r' is supposed to be 'x'.

⸻⸻⸻⸻

[tex]y=11r-4\\------------\\\rightarrow -4 = 11(0) - 4\\\\\rightarrow -4 = 0 -4\\\\\rightarrow \boxed{-4=-4}[/tex]

⸻⸻⸻⸻

The ordered pair is a solution. You can also tell that it is a solution because the equation given is in slope-intercept form, and '-4' is in b's spot.

⸻⸻⸻⸻

[tex]y = mx+b[/tex]

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.
