Tameca already has $55 dollars in her savings account. If she puts $5 per week in her account, write and solve an inequality to find out how many weeks she must save to have at least $100 in her account.

Answer:

Step-by-step explanation:

35 a + 34 b = 163.50 (given)

15 a + 17 b = 76.50 (given) multiply this equation by -2

-30 a - 34 b = -153.00 now add this equation to the first equation t get

5 a = 10.50 solve this for a (apple's price) then sub this value into one of the equations to find banana price, b.

Point :

A × B = B × A

Ex)

[tex] \frac{1}{2} \times \frac{3}{4} = \frac{3}{4} \times \frac{1}{2} = \frac{3}{2} \times \frac{1}{4} [/tex]

_________________________________

a )

[tex] \frac{12 {a}^{2} }{25 {b}^{3} } \times \frac{5b}{4 {a}^{4} } = \frac{12 {a}^{2} }{4 {a}^{4} } \times \frac{5b}{25 {b}^{3} } = \\ [/tex]

[tex] \frac{4 {a}^{2} \times 3 }{4 {a}^{2} \times {a}^{2} } \times \frac{5b}{5b \times 5 {b}^{2} } = \\ [/tex]

[tex] \frac{3}{ {a}^{2} } \times \frac{1}{5 {b}^{2} } = \frac{3}{5 {a}^{2} {b}^{2} } \\ [/tex]

_________________________________

b )

[tex] \frac{ {x}^{2} - 2x - 15 }{ {x}^{2} - 9 } \times \frac{ {x}^{2 } - 6x + 9 }{4x - 12} = \\ [/tex]

[tex] \frac{(x - 5)(x + 3)}{(x - 3)(x + 3)} \times \frac{(x - 3)(x - 3) }{4(x - 3)} = \\ [/tex]

[tex] \frac{(x - 5)}{(x - 3)} \times \frac{(x - 3)}{4} = \\ [/tex]

[tex] \frac{(x - 3)(x - 5)}{(x - 3) \: \: \: \times \: \: 4} = \frac{x - 5}{4} \\ [/tex]

Answer:

A.

Step-by-step explanation:

Use the pythagoreon theory

4^2+10^2=16^2

116=256

5^2+12^2=13^2

169=169

7^2+24^2=25^2

625=625

8^2+15^2=17^2

Answer:

25 buttons per package

Step-by-step explanation:

Answer:

I believe it is 25 buttons per package

Answer:

No

Step-by-step explanation:

3x-5=4+2x

x-5=4 (subtract 2x from both sides)

x=9 (add 5 to both sides)

Answer:

Step-by-step explanation:

x + 2y = 7   ⇒  x = 7 - 2y

- 2x + 3y = 14

- 2(7 - 2y) + 3y = 14

-14 + 4y + 3y = 14

-14 +7y +14 = 14 +14

   7y = 28

     y = 4

x = 7 - 2y = 7-2(4) = 7 - 8 = -1

Answer:

$5.00 ; no

Step-by-step explanation:

Given that:

135 / 360 = 0.375

90 / 360 = 0.25

135/ 360 = 0.375

X ___ 5 _____10 _____ 0

P(x): _0.25___0.375___0.375

Expected value :

ΣX*p(X) :

5(0.25) + 10(0.375) + 0(0.375)

1.25 + 3.75 + 0

= $5

b) If you have to pay $10 to play, is it a fair game?

For the game to be fair :

Amount paid = Expected winning

$10 ≠ $5

Since, amount paid is greater than expected winning, then the game is not fair

Answer:

a. 1.5 and 9

b. 3

Answer:

The fourth term is 11 and the tenth term is 29

Step-by-step explanation:

Let us use the given formula to solve the question

∵ A(n) = 2 + (n - 1)(3) is the formula of the nth term of an sequence

∵ n is the position of the term in the sequence

∴ For the fourth term n = 4

∴ For the tenth term n = 10

→ Substitute n by 4 in the formula above to find the fourth term

∵ A(4) = 2 + (4 - 1)(3)

∴ A(4) = 2 + (3)(3)

∴ A(4) = 2 + 9

∴ A(4) = 11

∴ The fourth term is 11

→ For the tenth term put n = 10

∵ n = 10

∵ A(10) = 2 + (10 - 1)(3)

∴ A(10) = 2 + (9)(3)

∴ A(10) = 2 + 27

∴ A(10) = 29

∴ The tenth term is 29

Answer:

207

Step-by-step explanation:

It automatically can not be -207 and -21 because you can't have a negative distance. To find the correct answer between 21 and 207, first you have to add 93 and 114. You do this because -93 is below the number line, so you have to add it to 114. 114 + 93 = 207

207

Answer:

18 quilômetros

Step-by-step explanation:

Aqui, queremos determinar a distância máxima que pode ser percorrida com R $ 20

A partir da pergunta, entendemos que cada viagem tem um valor fixo de R $ 3,44 e um valor variável de R $ 0,90 com base na quantidade de quilômetros.

Seja x o número de quilômetros percorridos em R $ 20 Portanto, temos a equação como; 3,44 + 0,9 (x) = 20

0,9x = 20-3,44

0,9x = 16,56

x = 16,56 / 0,9

x = 18,4

Arredondando para o quilômetro mais próximo, a distância máxima que pode ser percorrida com R $ 20 é de 18 quilômetros

Answer:

24  h^16

Step-by-step explanation:

4h ^10 · 6h^6

Multiply the constants

4*6 = 24

Since the bases are the same, add the exponents

h^10 * h^ 6 = h^ ( 10+6) = h^16

24  h^16

Answer:

31.25miles per gallon

Step-by-step explanation:

Distance traveled  = 100miles

Quantity of gasoline used  = 3.2gallons

Unknown:

Rates of distance traveled to fuel used = ?

Solution:

 The rates of distance traveled to fuel used is given as;

   Rates  = [tex]\frac{distance traveled}{fuel used }[/tex]

Input the parameters and solve;

   Rates  = [tex]\frac{100}{3.2}[/tex]   = 31.25miles per gallon

Answer:

h = 42y

Step-by-step explanation:

The number of hats h she can knit varies directly with the amount of yarn (y) in yards she has.

h = ky

Where,

h = the number of hats she can knit

y = amount of yarn she has(yards)

k = constant of people = 42

Eequation to represent the relationship between the number of yards of yarn Paula has and the number of hats she can knit.

h = 42y

[tex]4x + 3 = 3x + 12[/tex]

Both sides minus 3

[tex]4x = 3x + 12 - 3[/tex]

[tex]4x = 3x + 9[/tex]

Both sides minus 3x

[tex]4x - 3x = 9[/tex]

[tex]x = 9[/tex]

So :

TVU = 3(9)+12 ----¢ TVU = 27 + 12

TVU = 39°

Answer:

C. Slope of Function A = 2 x Slope of Function B

Step-by-step explanation:

The slope of function A is the x-coefficient: 6.

The slope of function B is ...

... slope = (change in y)/(change in x) = (-2-4)/(-1-1) = -6/-2 = 3

6 is 2 times 3

Answer:

  b  1/4 (n-64)

Step-by-step explanation:

Multiplying the expression by 1 does not change its value:

  = (1/4)(4) × (1/4n -16)

  = (1/4) × (4(1/4n -16)) . . . . . associative property

  = (1/4) × ((4/4)n -4·16) . . . . distributive property

  = (1/4)(n -64) . . . . matches choice B

Answer:

An hour is 60 minutes.

And according to question we have to find the simplest form of 60/4

4/60

=  1/15

So the fraction is 1/15
