Answer:

-3d + 3 < 18 (subtract 3 from both sides)

-3d < 15 (divide both sides by -3)

d > -5 (this is your answer, when you divide by a negative number in an inequality, the sign flips the other way)

Step-by-step explanation:

Let the number of songs = m.

The cost of downloading 1 songs = $60

So, the cost of downloading 'm' songs = < dollars

Since, the maximum amount she can spend on downloading songs is $60.

So, we get the inequality, .99m < 60

Hence, the inequality representing the situation is . A

Answer:

A linear equation can be written in many ways, so the way we can use to solve a system of linear equations depends on the form the system is written. There are several methods to do this, the more common are: Method of Equalization, Substitution Method, Elimination Method.

Answer:

65700 seconds a year for 2 times a day

Step-by-step explanation:

The required time an average individual spent time on brushing their teeth in a year is 65700 seconds.

The process in mathematics to operate and interpret the function to make the function or expression simple or more undertandable is called simplifying and the process is called simplification.

Here,
it's approximately 90 seconds for the average person to brush his or her teeth and a person brushes their teeth twice daily.
1 year = 365 days
And in a person spends 90 + 90 seconds brushing their teeth,
Time spent on brushing teeth in 1 year = 180 × 365 = 65700  seconds.

Thus, the required time an average individual spent time on brushing their teeth in a year is 65700 seconds.

Answer:

Step-by-step explanation:

Answer:

x = 5 cm.

Step-by-step explanation:

Since this is a right triangle, we can just use Pythagorean Theorem to find the hypotenuse:

a² + b² = c²

3² + 4² = x²

9 + 16 = x²

25 = x²

5 = x

Therefore, x is 5 cm.

Answer:

1/6

Step-by-step explanation:

. he missed 30 mins and 3 hours is 180 mins .30/180. simplified its 1/6

The fraction of the variety show does he miss is 1/6 and this can be determined by using the arithmetic operations and unitary method.

Given :

Christian is 30 minutes late for a variety show that is three hours long.

The following steps can be used to determine the fraction of the variety show does he miss:

Step 1 - Remember one hour is equal to 60 minutes.

Step 2 - Convert three hours in minutes by using the unitary method. If one hour is equal to 60 minutes then 3 hours is equal to:

[tex]=\dfrac{3}{1}\times 60[/tex]

= 180 minutes

Step 3 - To determine the ratio of the variety show does he miss, divide 30 minutes by 180 minutes.

[tex]=\dfrac{30}{180}[/tex]

= [tex]\dfrac{1}{6}[/tex]

So, the fraction of the variety show does he miss is 1/6.

Answer:

3 hours and 40 minutes I think

Step-by-step explanation:

Answer:

3 hours and 40 mins

Step-by-step explanation

First, you check 3 hours times 50 miles and 3 hours times 60 miles to get how close they are. 3x50=150, and 3x60=180. 150+180=330. Then you multiply 4/6 or 2/3 by 5 and 6 then add them (because 40 mins is 2/3 of an hour) 50x2/3/2=100/3 and 60x2/3=120/3=40. 40+50/3=73 1/3. 73 1/3+330= 3 hours and 40 mins.

Step-by-step explanation:

The answer is 10.

Answer:

a=2

b=0

c=12

Step-by-step explanation:

The standard form of a quadratic equation is ax²+bx+c=0

Here's the given equation:

2x²+12=0

You might notice that the term bx is not there (there is just ax² and c). That means that b is 0.

The term 2x² is the term ax² in this equation. The coefficient in the term is 2, so that means that a is 2

12 has no variable, so that means it'll be c in the equation.

Answer:

19.7

Step-by-step explanation:

We need to find the hypotenuse of the blue triangle, as stated in the hint. We know the sides of the base measure 8 x 15 respectively so let's use Pythagorean Theorem;

8^2 + 15^2 = (hyp.)^2,

hyp = √8^2 + 15^2 = √64 + 225 = √289 = 17

Now the height of the yellow triangle is 10 inches. The hypotenuse of the blue triangle is now the base of the yellow triangle. The dimensions are 10 x 17 respectively so we can determine it's hypotenuse;

hyp (yellow triangle) = √17^2 + 10^2

                                   = √289 + 100

                                   = √389 ≈ 19.7 in.
