.Mai and Noah each leave their houses at ther same time and ride their bikes to the park. Using information
from the data card provided, choose the equation for Noah that relates the time in minutes (t) to the distance in meters they travel

Answers

Answer 1

Answer:

Let's define the zero in our axis as the park.

We know that Noah lives 9,000 meters away from the park, and that he bikes 300 meters per minute.

Then at the beginning, the position of Noah with respect to the park can be written as:

P(0s) = -9000m

This means that initially he is 9000m away from the park.

Now, each minute he moves 300 meters to the park, then after t minutes, the position is:

P(t) = -9000m + (300m/min)*t

With this equation we can find the time that takes Noah to arrive at the park:

When his position is equal to zero, it means that he is in the park (because we defined the position zero as the park).

P(t) = 0m = -9000m + (300m/min)*t

Now we can solve this for t.

9000m = (300m/min)*t

9000m/((300m/min) = t = 30 minutes.

Answer 2

Answer:

Noah arrived first.

Step-by-step explanation:

6x-2x=24 HELP PLSSSSSS

Answers

Answer:

x=6

Step-by-step explanation:

Basically since 6x and 2x have like terms you subtract the 2x from 6x.

6x-2x=4x

Then you divide 4 from 24.

4x=24

4x/4 = 24/4

x=6

Answer:

6x - 2x = 24

4x = 24

4x ÷ 4 = 24÷4

x = 6

Step-by-step explanation:

First of all subtract 2x from 6x which will give you 4x = 24

since you're finding x or want to make x the subject you are to divide both sides by 4, so

4x ÷ 4 will give you x, since both 4's will cancel out giving you x =, then you divide 24 by 4 also. 24 ÷ 4 will give you 6, so x = 6.

Multi step equations
Show worm

Answers

Answer:

a = -1

Step-by-step explanation:

First, combine like terms. Like terms are terms with the same amount of the same variables.

6a + 5a = -11

(6a + 5a) = -11

(11a) = -11

Isolate the variable, a. Note the equal sign, what you do to one side, you do to the other. Divide 11 from both sides:

(11a)/11 = (-11)/11

a = -11/11

a = -1

a = -1 is your answer.

Step-by-step explanation:

Answer:

The answer is 190.5cm

Step-by-step explanation:

so solve this problem, we first need to convert marco's height to inches.

there are 12 inches in 1 foot.

multiply.

[tex]\frac{6ft}{1} *\frac{12inch}{1ft} \\72inch[/tex]

notice how ft cancel out because they are in opposite positions of the fraction.

add 72+3 to get marco's height in inches.

marco is 75inches.

with this information, we can solve for his height in cm.

write an equation.

[tex]\frac{75inch}{1} *\frac{2.54cm}{iinch}[/tex]

Dominic is going to drive from his house to City A without stopping. Dominic's house is 300 miles from City A and he plans to drive at a speed of 50 miles per hour. Write an equation for D, in terms of t,t, representing Dominic's distance from City A t hours after leaving his house.

Answers

Answer:

D= −50t + 300

Step-by-step explanation:

Since Dominic lives 300 miles from City A, when he starts his trip (at time

t=0), his distance from City A must be 300 miles, meaning D=300 when

t=0, which is the y−intercept.

(0,300) is a point on the graph

Since Dominic will drive 50 miles per hour, the Dominic's distance from City A decrease 50 miles for each hour of driving, making the slope of D equal to

−50.

Slope=−50

equation of the line: D= −50t + 300

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The equation for D, in terms of t, represents Dominic's distance from City A t hours after leaving his house.

D = 300 - 50t

Where t= number of hours

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x = 4 is an equation.

We have,

Distance between Dominic's house and City A = 300 miles

Speed = 50 miles per hour.

The equation for D, in terms of t, represents Dominic's distance from City A t hours after leaving his house.

D = 300 - 50t

Where t= number of hours

Now,

We can see that,

At t = 1, D = 300 - 50 = 250 miles.

At t = 2, D = 300 - 100 = 200 miles.

Thus,

The equation for D, in terms of t, represents Dominic's distance from City A t hours after leaving his house.

D = 300 - 50t

Where t= number of hours

During a musical an orchestra is playing. As the music plays, the volume changes in the beginning of the piece can be modeled by the equation s = 10│x - 4│+ 50 where s represents the sound level in decibels and x represents the number of measures of music played. At what number(s) measures played would the sound level be at 80 decibels?

Answers

Answer:

The sound level would be at 80 decibels at 1 or 7 number of measures played

Step-by-step explanation:

Equations with Absolute Values

We have the function s to represent the sound level in decibels:

[tex]s = 10|x - 4|+ 50[/tex]

Where x is the number of measures of the music played.

We are required to find the value of x that makes s=80 decibels. We have to find the equation:

[tex]10|x - 4|+ 50 =80[/tex]

Subtracting 50:

[tex]10|x - 4| =80-50[/tex]

[tex]10|x - 4| =30[/tex]

Dividing by 10:

[tex]|x - 4| =30/10=3[/tex]

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

For the absolute value be equal to 3, its argument could be positive or negative:

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

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

This leads us to two solutions:

[tex]x=3+4=7[/tex]

x=7

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

[tex]x=4-3=1[/tex]

x=1

The sound level would be at 80 decibels at 1 or 7 number of measures played
