-301 = -3x = 7(4x – 18)

-301 = -3x = 28x - 126

-301 = 31x = -126

-175 = 31x

x = -175/31

Lauren spent $3.26 for lunch on Tuesday. She spent $3.56 on Wednesday and $3.29 on Thursday. Order the prices from greatest to least. Draw a number line to support my the answer

Answers

3.56,3.29,3.26
I kinda need points here so:/

The number line visually shows the order of the prices, with $3.56 on the right (the greatest), followed by $3.29, and then $3.26 on the left (the least).

$3.56    $3.29     $3.26

  |------------|------------|

To order the prices from greatest to least, we'll compare the amounts spent on each day:

1. Wednesday: $3.56

2. Thursday: $3.29

3. Tuesday: $3.26

So, in order from greatest to least, the prices are:

$3.56 > $3.29 > $3.26

Now, let's represent this order on a number line:

 $3.56        $3.29        $3.26

  |------------|------------|

The number line visually shows the order of the prices, with $3.56 on the right (the greatest), followed by $3.29, and then $3.26 on the left (the least).

Find the least common multiple of 9 and 15

Answers

Answer:

45

Step-by-step explanation:

9:9,18,27,36,45

15:15,30,45

Answer:

45

Step-by-step explanation:

The least common multiple is the smallest number found between the two numbers, in this case 9 and 15, while skip counting from each number. Or the like the multiplication table.

Multiples for 9:

9, 18, 27, 36, 45, 54, 63...

Multiples for 15:

15, 30, 45, 60, 85...

45 is the first and common number that appears in both multiples of 9 and multiples of 15. Therefore, it will be the least common multiple of 9 and 15.

Find the minimum value of the function:
f(x) = x2 + 9x – 16.

Answers

complete the square by halving the x coefficient and putting that in a squared bracket with x:

(x + 4.5)^2

This will give us an extra 20.25 we don’t want, so takeaway 20.25:

(x + 4.5)^2 — 20.25

Takeaway the 16 in the question:

(x + 4.5)^2 - 20.25 - 16 = (x + 4.5)^2 - 36.25

The minimum x coordinate is the number in the bracket with the opposite sign, thus the answer is -4.5 (the minimum y coordinate is the number outside the bracket with the same sign, -36.25)

A bag contains 7 red marbles, 8 blue marbles, and 9 green marbles. What is the
probability of choosing a blue marble when one marble is drawn?

Answers

Answer:

The probability of choosing a blue marble is 1/3.

Step-by-step explanation:

Add up all of the marbles.

7+8+9=24.

Next, you get the fraction of the chosen marble type over all marbles. In this case, it's blue, so it's 8/24

Finally, you must simplify the fraction.

1/3 is the simplest form of 8/24.

If it costs $5.35 per day for a 5 day work week to ride the bus, and a weekly pass is $25, how much could a person save by buying the pass?

Answers

Answer:

$1.75

Step-by-step explanation:

basically we are comparing

5 daily passes vs. a weekly pass.

5 daily passes = 5×$5.35 = $26.75

a weekly pass = $25.00

so, the difference is 26.75 - 25 = $1.75

Hello!

The first thing you need to do in this problem is calculate how much it would cost to ride the bus 5 days a week WITHOUT the pass. Since you know there are 5 days in a week, and each day costs 5.35 dollars, multiply those two numbers together.

5*5.35= $26.75

Now, we are trying to find out how much more that is than the bus pass, since we are trying to find how much you can save by buying the bus pass. To do that, subtract 25 dollars (the cost of the bus pass) from the cost without the bus pass (26.75 dollars.)

26.75-25=1.75


Therefore, your answer is the first one: $1.75

The length of a rectangle is three times its width. It the perimeter of the rectangle is 96m,  find the length and breadth of the rectangle ​

Answers

Let the width, w = x m

So, according to the Question,

The length, l = 3x m

Perimeter of a rectangle = 2 (l + w) m

Perimeter of the rectangle = 96 m

It's equation will be,

2 (3x + x) m = 96 m

or, 4x m = 96/2 m

or, 4x m = 48 m

or, x m = 48/4 m

or, x m = 12 m

Therefore, the width and the length of the rectangle is 12 m and 3(12) m = 36 m respectively.
