Answer:

it's ¢.34

Step-by-step explanation:

a gallon has 16 cups

since there are two gallons that's 32

the price of the two gallons divided my 32 is how much each cup would be so 10.88/32 would be ¢.34

Answer:

Smaller number: 12

Greater number: 31

Step-by-step explanation:

Hi there!

Let x equal to the smaller number.

Let y be equal to the greater number.

1) Translate the information into equations

"One is 7 more than twice the other"

⇒ [tex]y=2x+7[/tex]

"The sum of the numbers is 43"

⇒ [tex]x+y=43[/tex]

2) Use substitution to solve for the smaller number

[tex]x+y=43[/tex]

Plug the equation [tex]y=2x+7[/tex] into the above equation

[tex]x+(2x+7)=43\\x+2x+7=43\\3x+7=43[/tex]

Subtract both sides by 7

[tex]3x+7-7=43-7\\3x=36[/tex]

Divide both sides by 3 to isolate x

[tex]\frac{3x}{3} = \frac{36}{3} \\x=12[/tex]

Therefore, the smaller number equates to 12.

3) Use substitution to solve for the greater number

[tex]x+y=43[/tex]

Plug in x as 12

[tex]12+y=43[/tex]

Subtract both sides by 12 to isolate y

[tex]12+y-12=43-12\\y=31[/tex]

Therefore, the greater number equates to 31.

I hope this helps!

Answer:

a) 42

b) -24

Step-by-step explanation:

Recordar las reglas de los signos:

(-)*(-) = (+)

(+)*(-) = (-)

(-)*(+) = (-)

(+)*(+) = (+)

Tambien la propiedad distributiva:

A*(B + C + D) = A*B + A*C + A*D

Queremos calcular:

a) (-7)*(+3)*(-2)  

Los primeros dos terminos dan:

-(7*3)*(-2) = -(21)*(-2) = (-21)*(-2) = +(21*2) = +42

b) -4*( + 3 - 2 + 5)

= (-4)*(3) + (-4)*(-2) + (-4)*(5)

= - 12 + 8 - 20 = 8 - 32 = -24

Answer:

this is the correct answer

Answer:

The sequence is geometric

The common ratio is 0.5

Step-by-step explanation:

In the arithmetic sequence, there is a common difference between each two consecutive terms

In the geometric sequence, there is a common ratio between each two consecutive terms

Let us check the given sequence

∵ The first 3 terms are 12, 6, 3

∵ 6 - 12 = -6

∵ 3 - 6 = -3

∵ There is no common difference between the consecutive terms

∴ The sequence is not an arithmetic sequence

∵ 6 ÷ 12 = 0.5

∵ 3 ÷ 6 = 0.5

∴ There is a common ratio between each two consecutive terms

∴ The sequence is a geometric sequence

∴ The common ratio is 0.5

Answer:

10.2% but there is a chance of it being 8.8%

Step-by-step explanation:

there are total of 18 marbles to start

of this at the begining there is a 8/18 chance to draw a marble, now here is where it can get tricky so ive organized them into different groups, A and B

Option A: The Marbles are removed after

this would make the problem be 8/18 x 7/17 x 6/16

4/9 x 7/17 x 3/8 or 84/1224

simplify 42/612

simplify 21/306

(21/306) x 100 = 10.2%

Option B: The Marbles arent removed after

8/18 x 8/18 x 8/18

4/9 x 4/9 x 4/9

64/729 = .08779

.08779 x 100 = 8.8

8.8%

It depends on what youve learned in class, i would go with option A

-Gage Millar, Algebra 2 tutor

Given x+x-¹ = 11

now square both the side

(x+x-¹)² = 11²

now open the bracket of RHS and apply (a+b)²

you'll get,

x²+2x/x+ 1/x² =121

simplify above equation you'll get,

x²+ 2 + x-² = 121

shift the equation,

x² + x-² = 121 - 2

x² + x-² = 119 !

Answer:

$207.66

Step-by-step explanation:

30% off is the same as saying there is 70% not off, and 70% is the same as 0.70

0.70*349= 244.30

15% off is the same as saying 85% is not off, and

85% is the same as 0.85

0.85*244.30=207.655

because it's money, you round to 2nd decimal place

$207.66

Answer:

y = -1/4x^2 - x + 3

Step-by-step explanation:

(-6,0)

(-4,3)

(2,0)

36a - 6b + c = 0

16a -4b + c = 3

4a + 2b + c = 0

c = -4a - 2b

36a - 6b - 4a -2b = 0

16a - 4b -4a - 2b = 3

32a -8b = 0

12a - 6b = 3

4a - b  = 0

4a - 2b = 1

b = -1

4a + 1 = 0

4a = -1

a = -1/4

c = 1 + 2 = 3

y = -1/4x^2 - x + 3

Answer:

Step-by-step explanation:

y = ax² + bx + c

( - 6)²a - 6b + c = 0 ⇒ 36a - 6b + c = 0

( - 4)²a - 4b + c = 3 ⇒ 16a - 4b + c = 3

2²a + 2b + c = 0 ⇒ 4a + 2b + c = 0

A = [tex]\left[\begin{array}{ccc}36&-6&1\\16&-4&1\\4&2&1\end{array}\right][/tex] = - 96

[tex]A_{a}[/tex] = [tex]\left[\begin{array}{ccc}0&-6&1\\3&-4&1\\0&2&1\end{array}\right][/tex] = 24

[tex]A_{b}[/tex] = [tex]\left[\begin{array}{ccc}36&0&1\\16&3&1\\4&0&1\end{array}\right][/tex] = 96

[tex]A_{c}[/tex] = [tex]\left[\begin{array}{ccc}36&-6&0\\16&-4&3\\4&2&0\end{array}\right][/tex] = - 288

a = [tex]\frac{A_{a} }{A}[/tex] = [tex]\frac{24}{-96}[/tex] = - [tex]\frac{1}{4}[/tex]

b = [tex]\frac{A_{b} }{A}[/tex] = - 1

c = [tex]\frac{A_{c} }{A}[/tex] = 3

y = - [tex]\frac{1}{4}[/tex] x² - x + 3
