Answer:

[tex]\$0.92[/tex]

Step-by-step explanation:

Let cost of 1 marker be [tex]x[/tex] and 1 pencil be [tex]y[/tex]

From the question we get two equations

[tex]3x+2y=2.2\quad ...(i)[/tex]

[tex]4x+6y=3.4\quad ...(ii)[/tex]

Multiply the first equation by 3 [tex](i)\times3[/tex]

[tex]9x+6y=6.6\quad ...(iii)[/tex]

[tex]4x+6y=3.4\quad ...(iv)[/tex]

Subtracting the above equations [tex](iii)-(iv)[/tex] we get

[tex]5x=3.2\\\Rightarrow x=\dfrac{3.2}{5}\\\Rightarrow x=0.64[/tex]

[tex]4x+6y=3.4\\\Rightarrow y=\dfrac{3.4-4x}{6}=\dfrac{3.4-4\times 0.64}{6}\\\Rightarrow y=0.14[/tex]

One marker costs $0.64 and one pencil costs $0.14

Cost of 1 marker and 2 pencils is [tex]0.64+0.14\times 2=\$0.92[/tex].

Answer:

Now, we’re going to consider an example of proportional relationship in our everyday life: When we put gas in our car, there is a relationship between the number of gallons of fuel that we put in the tank and the amount of money we will have to pay. In other words, the more gas we put in, the more money we’ll pay.

Step-by-step explanation:

hope this helps

Answer:

Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality". Some textbooks describe a proportional relationship by saying that " y varies proportionally with x " or that " y is directly proportional to x .") This means that as x increases, y increases and as x decreases, y decreases-and that the ratio between them always stays the same.

Answer:

1 1/2 hours = 90 minutes

Step-by-step explanation:

Devon records 4 hours of reality shows on her dvr she records comedy shows 3/8 of that amount of time. Devon watches all the reality and comedy shows in half hour sittings. Find the number of hours of comedy shows that Devon records

Total hours of reality show = 4

Comedy shows = 3/8 of 4 hours

Number of hours of comedy shows that Devon records = 3/8 of 4 hours

= 3/8 × 4

= 12 / 8

= 1 4/8

= 1 1/2

Number of hours of comedy shows that Devon records = 1 1/2 hours

There are 60 minutes in an hour

1 1/2 hours = 1 1/2 × 60 minutes

= 3/2 × 60

= 180 / 2

= 90 minutes

Therefore,

1 1/2 hours = 90 minutes

Answer:

The answer is A. A+C because Rational numbers can be made by dividing two integers. integers are whole numbers a number that is not a fraction.

Amount of tip she gave,

[tex]T = 15\times 0.20\\\\T =\$3[/tex]

Amount of tax given :

[tex]Tax=15\times 0.09\\\\Tax = \$1.35[/tex]

So, total amount she paid is :

Total = Actual cost + Tip + Tax

Total = $(15 + 3 + 1.35 )

Total = $19.35 .

Therefore, total amount she paid is $19.35 .

Hence, this is the required solution.

Answer:Simplifying

3(2w + -7) = 3

Reorder the terms:

3(-7 + 2w) = 3

(-7 * 3 + 2w * 3) = 3

(-21 + 6w) = 3

Solving

-21 + 6w = 3

Solving for variable 'w'.

Move all terms containing w to the left, all other terms to the right.

Add '21' to each side of the equation.

-21 + 21 + 6w = 3 + 21

Combine like terms: -21 + 21 = 0

0 + 6w = 3 + 21

6w = 3 + 21

Combine like terms: 3 + 21 = 24

6w = 24

Divide each side by '6'.

w = 4

Simplifying

w = 4

Answer:

m = -4

Step-by-step explanation:

[tex] \frac{1}{9} (2m-16)= \frac{1}{3} (3m+4)[/tex]

[tex] \frac{2}{9} m - \frac{16}{9} = \frac{3}{3} m + \frac{4}{3} [/tex]

[tex] \frac{2}{9} m - m = \frac{4}{3} + \frac{16}{9} [/tex]

[tex] \frac{2}{9} m - \frac{9}{9} m = \frac{12}{9} + \frac{16}{9} [/tex]

[tex] \frac{2m - 9m}{9} = \frac{12 + 16}{ 9} [/tex]

[tex]2m - 9m = 12 + 16[/tex]

[tex] - 7m = 28[/tex]

[tex]m = \frac{28}{ - 7} [/tex]

Answer:

2.704814e+300

is what I got

The value of the given number 1 x 10¹⁰⁰ by applying the logarithms is equal to 100.

To find the number represented by 1 x 10¹⁰⁰ using logarithms, we can use the base-10 logarithm function.

The logarithm (base-10) of a number x is denoted as log(x) and represents the power to which 10 must be raised to get the number x.

Here, we have 1 x 10¹⁰⁰, and we want to find the value of x.

Using the logarithmic expression:

log(1 x 10¹⁰⁰) = log(1) + log(10¹⁰⁰)

The logarithm of 1 (log(1)) is equal to 0, so the expression simplifies to:

log(1 x 10¹⁰⁰) = 0 + log(10¹⁰⁰)

Now, using the property of logarithms, log(aᵇ) = b × log(a):

log(1 x 10¹⁰⁰) = 0 + 100 × log(10)

The logarithm of 10 (log(10)) is equal to 1, so:

log(1 x 10¹⁰⁰) = 0 + 100 × 1

Finally:

log(1 x 10¹⁰⁰) = 100

Therefore, the value of the number 1 x 10¹⁰⁰ using logarithms is 100.

Looks like you gave the answer already.

a = 8 and c = 5.5

Step-by-step explanation:

2a + 4c = 38.00  --> x3 --> 6a + 12c = 144

3a + 3c = 40.50 --> x2 --> 6a + 6c = 81

6c = 33

Answer: it would be A. -4

Step-by-step explanation:

Got it right on the test

Option A is correct, the value of the polynomial's constant term is -4.

According to the remainder value theorem, if a polynomial is divided by (m+1) and the remainder is 0, it means that (m+1) is a factor of the polynomial.

The given polynomial is -2m³ + m² - m + ___

To find the constant term, we need to determine the value of the polynomial when m = -1 (since (m+1) = 0).

Substituting m = -1 into the polynomial, we get:

-2(-1)³ + (-1)² - (-1) + ___

Simplifying the expression, we have:

-2(-1) + 1 + 1 + ___

-(-2) + 1 + 1 + ___

2 + 1 + 1 + ___

4 + ___

Since the polynomial is divided by (m+1) and the remainder is 0, the constant term must be -4 to cancel out the 4 term and make the expression equal to zero.

Therefore, the value of the polynomial's constant term is -4.

Answer: i) [tex]p=\dfrac{d-3}{2}[/tex]

ii) He has to attend 5 practices to run 13 miles.

Step-by-step explanation:

Given: The distance (d) in miles that Cecil runs depends on the number of track practices (p) he attends.

[tex]d=2p+3[/tex]

i) To solve for p . first subtract 3 from both sides , we get

[tex]d-3=2p[/tex]

Divide both sides by 2

[tex]\dfrac{d-3}{2}=p[/tex]

So. [tex]p=\dfrac{d-3}{2}[/tex]

ii) Put d= 13 , we get

[tex]p=\dfrac{13-3}{2}=\dfrac{10}{2}=5[/tex]
