Answer:

a possible solution is (10,1)

Step-by-step explanation:

Here, we want to solve the given inequality and determine one possible solution

From the question, we have it that;

x + y ≤ 13

Mathematically, we have it that 1 dime is worth $0.1

A nickel is worth $0.05

0.1x + 0.05y ≥ 0.95

please check the attachment for the graph of both equations

The point of intersection represents the solution.

we have a point here as (10,1)

Answer:

160miles

Step-by-step explanation:

400miles uses15g what about 6g.

Using cross multiplication. Multiply 6x400/15 = 160miles

Answer:

160 miles

Step-by-step explanation:

If it travels 400 miles on 15 gallons, then it will travel x miles on 6 gallons

400 miles -> 15 gallons

x miles -> 6 gallons

15 * x = 6 * 400

15x = 2400

x = 2400 / 15

x = 160 miles

Answer:

B

Step-by-step explanation:

Let say, a=9,b=11,c=6

Then associative properties says that every element is related to each other, here "b" associates a &c.

Therefore, a is related to b+c

c is related to a+b

Answer:

c/2=-4

c=-8

Step-by-step explanation:

Answer:

c = -8

Step-by-step explanation:

Okay, so this is a standard equation, so we have to do the thingy thing on each side:

c/2 + 5 - 5 = 1 - 5

c/2 = -4

c/2 x 2 = -4 x 2

c = -8

So, c = -8

Answer:

other root: x = 9

p = 7

Step-by-step explanation:

first, find p:

(8)² - (3p - 4)8 + 11p -5 = 0

64 - (24p - 32) + 11p - 5 = 0 –––––> 64 - 24p + 32 + 11p - 5 = 0

91 - 13p = 0

-13p = -91

p = 7

plug in p to find the polynomial:

x² - (3(7) - 4)x + 11(7) - 5 = 0

x² - (21 - 4)x + 77 - 5 = 0

x² - 17x + 72

find the roots:

we know that 8 is one of the roots, so one factor is (x - 8)

the other number needs to be something that equals -17 when added with -8 and 72 when multiplied by -8

that number is -9

so the poly nomial factors to be: (x-8)(x-9)

so the roots are x = 8 and x = 9

Answer:

p = 7

Step-by-step explanation:

x²-(3p-4)x+11p-5=0    ...(1)    Root: 8, x-8 is factor

(x-8) (x- (11p-5)/8) = 0

x² -8x - ((11p-5)/8)*x + (11p-5) = 0

x² - (8 + (11p-5)/8) x + 11p-5 = 0   ----(2)

compare(1) and (2): 3p-4 = 8 + (11p-5)/8

24p - 32 = 64 + 11p - 5

13p = 91

p = 7

check: x²-(3p-4)x+11p-5 = x²- 17x + 72 = (x-8)(x-9)

Answer:

Angle 8 is 100 degrees.

Step-by-step explanation:

Corresponding angles (angles on the same spot in the transversal) are equal to each other. For example angle 2 will be equal to angle 6.

Answer:

4.85

Step-by-step explanation:

Given :

Negative 0.2 (x minus 4) = negative 1.7

-2(x - 4) = - 1.7

-2x + 8 = - 1.7

-2x = - 1.7 - 8

-2x = - 9.7

Divide both sides by - 2

-2x / 2 = - 9.7 / - 2

x = 4.85

Answer:

1:4

Step-by-step explanation:

Given

3: 12

To express in the form 1:n

Consider how to make 3 equal to 1, we simply divide 3 by 3 to get 1 as such, we would also divide 12 by 3

3:12

= 3/3:12/3

= 1:4

Comparing with 1:n, it is safe to say that n = 4

Answer: −8x+24y+72

-8(x - 3y - 9)

=(-8)(x + -3y + -9)

=(−8)(x)+(−8)(−3y)+(−8)(−9)

=−8x+24y+72

Step-by-step explanation:

im not entirely sure but i hope this helps

:) have a nice day !!

Step-by-step explanation:

[tex] {3}^{3x - 4} = {9}^{x} \\ {3}^{3x - 4} = {3}^{2x} [/tex]

3x - 4 = 2x

3x - 2x = 4

x = 4

Answer: 25

Step-by-step explanation:

if she has 120 and if she has 20 leftover that means she used a 100. then u divide 100 by 4 cause it's a square and u get 25

Answer: A is the answer (7,9)

Answer:

Bc = √63 ft

Step-by-step explanation:

Here, we want to get the length of BC

As we can see, there is a right angled triangle ABC, with 12ft being the hypotenuse and 9 ft the other side

So we want to get the third leg which is BC

we can use the Pythagoras’ theorem here

And that states that the square of the hypotenuse equals the sum of the squares of the two other sides

let the missing length be x

12^2 = x^2 + 9^2

144 = x^2 + 81

x^2 = 144-81

x^2 = 63

x = √63 ft
