Answer:

-9 < -1

21/5 < 17/4

Step-by-step explanation:

A) when a number isnegitv ethe "smaller" number has more value. You would rather loose one doller than 9, right?

B) 21/5 = 4.20

17/4 = 4.25

and .25 os bigger than .20

Rzqust [24]

The number of students that are on the track team are 18.

The number of students that are on the baseball team are 15.

<h3>What are the linear equations that represent the question?</h3>

a + b = 33 equation 1

a - b = 3 equation 2

Where:

  • a = number of students that are on the track team
  • b = number of students that are on the baseball team

<h3>How many students that are on the baseball team?</h3>

Subtract equation 2 from equation 1

2b = 30

Divide both sides by 2

b = 30/2 = 15

<h3>How many students that are on the track team?</h3>

Subtract 15 from 33: 33 - 15 = 18

Answer:

  20 + 3x ≥ 50

Step-by-step explanation:

After x days, John will have added 3x points to his total. The new total will be ...

  20 +3x

We want that value to be at least 50, so we use the symbol "greater than or equal to" to express that relationship:

  20 +3x ≥ 50

_____

Brainly makes available a table of math symbols so you can choose the appropriate one to use in your expression. The number 2 is not the same as the symbol ≥. Using incorrect symbols makes it very difficult to tell what the intended problem is.

Answer:

30

Step-by-step explanation:

We can determine the number of different sets of reports by determining how many possible options are available per subject and then multiplying them.

There are 5 total options for geography, 3 for English, 1 for sciences, and 2 for maths. Multiplying these gets us 30.

Compare the speed of the train to the speed of the card. How much less time would it be for Lisa to travel 231 miles using the f
Bingel [31]

Answer:

Faster mode: Car

Less time: 0.93 hour

Step-by-step explanation:

Given

y = 55x --- The equation of travelling by car

See attachment for missing details

Required

Determine by how much less time Lisa will travel 231 miles using the faster mode

First, we calculate the equation of travelling by train.

Start by calculating the slope (m)

m=\frac{y_2 - y_1}{x_2 - x_1}

Where

(x_1,y_1) = (2,90)

(x_2,y_2) = (4,180)

m = \frac{180 - 90}{4-2}

m = \frac{90}{2}

m = 45

The equation is then calculated using:

y = m(x - x_3) + y_3

Where

(x_3,y_3) = (6,270)

y = 45(x - 6) + 270

y = 45x - 270 + 270

y = 45x

So, we have:

y = 55x --- The equation of travelling by car

y = 45x --- The equation of travelling by train

Next, we calculate the speed travelled using both means for 231 miles.

For travelling by car: Substitute 231 for y in y = 55x

231 = 55 * x

x = \frac{231}{55}

x = 4.20

By car, Lisa travels for 4.20 hours

For travelling by train: Substitute 231 for y in y = 45x

231 = 45 * x

x = \frac{231}{45}

x = 5.13

By train, Lisa travels for 5.13 hours

So, the faster mode of transportation is the car:

The less time is:

5.13 - 4.20 =0.93\ hour

The less time spent is 0.93 hour
