Answer 2

There are 4 quarters in the box of coins.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

A box of coins contains nickels, dimes and quarters.

The value of the coins is $4.00.

And, There were 3 times as many nickels, half as many dimes, and 6 more quarters, the value of the coins would be $5.50.

Now,

Let number of nickels in a box = n

Number of dimes = d

Number of quarters = q

Here, The value of the coins is $4.00.

Hence, We get;

⇒ 5n + 10d + 25q = 400 cents .... (i)

And, There were 3 times as many nickels, half as many dimes, and 6 more quarters, the value of the coins would be $5.50.

Hence, we get;

⇒ 3(5n) + 5d + 25(q+6) = 550 cents

⇒ 15n + 5d + 25q + 150 = 500

⇒ 15n + 5d + 25q = 350 .. (ii)

After solving equation (i) and (ii), we get;

Number of nickels in a box = n = 12

Number of dimes = d = 24

Number of quarters = q = 4

What is a fraction?

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

Let, The numerator of a fraction represents the number of games lost and the denominator represents the total number of games played.

Therefore, The fractions that represent this context for all the teams are,

1/3, 1/9, 1/4 and 1/10.

We know the value of a fraction increase with the same numerator and smaller and smaller denominator.

So, The fraction 1/10 has the least value which indicates that it is the best performer.

Write an equation in point-slope form, slope intercept form, and standard form for a line that passes through (-2,8) with slope 8/5

please help :(((( don’t give answers if you aren’t sure

Answers

9514 1404 393

Answer:

y -8 = 8/5(x +2)y = 8/5x +56/58x -5y = -56

Step-by-step explanation:

Since you're given a point and slope, it is convenient to start with that form.

Point-slope form

y -k = m(x -h) . . . . . line with slope m through point (h, k)

y -8 = 8/5(x +2) . . . point-slope equation

Slope-intercept form

y = mx + b . . . . . line with slope m and y-intercept b

The above equation can be rearranged to this form.

y = 8/5x +16/5 +8

y = 8/5x +56/5 . . . . . slope-intercept form

Standard form

ax +by = c

Multiplying by 5 and subtracting the y-term gives the general form equation ...

5y = 8x +56

8x -5y +56 = 0

8x -5y = -56 . . . . . . add -56 to put into standard form

Solve for x: 4X -8 < 2x + 10

Answer:

Timmy wants to buy a scooter and the price was $150. When he goes to the store a

second time, he found that the price was marked down by 15%. Then when he gets to the

register the cashier tells him today only he gets an additional 10% off the sales price. What is

the final cost of the scooter including the discounts?

Answers

Answer:

112.5

Step-by-step explanation:

total discount: 25%

Answer:

Step-by-step explanation:

150*15% off =22.50 off total 127.50. Then he gets the 10% off 127.50*10%= 12.75 off total cost $114.75

It may look like 25% off at once, but most stores will do the discounts separately so they don't lose too much money.

The mean of the numbers is 9.

Mean is a measure of central tendency. It is the average of a set of numbers. The value of the mean of a set of numbers can be determined by adding the given numbers together and dividing it by the total number.

Mean = sum of numbers / total numbers

Sum of numbers = 7 + 21 + 2 + 17 + 3 + 13 + 7 + 4 + 9 + 7 + 9 = 99

Step-by-step explanation:

Equation: y = 6x

x = number of ice cream cones

y = 6(7) = 42

Hi! I believe your answer is $10.50. If it's $6 for 4 ice cream cones, divide 6 by 4 and you'll get 1.5, or $1.50 per ice cream cone. For 7 ice cream cones, multiply the unit rate ($1.50 per ice cream cone) by 7. The total cost is $10.50. I hope this helps you! Good luck and have a great day. ❤️✨

Answer:

(5x - 38)° = (3x - 4)°

2x = 34

x=17

(5(17)-38))=47

What are the properties of parallel lines?

Following are the properties of parallel lines,

The pairs of vertically opposite angles are equal.The pairs of corresponding angles are equal.The pairs of alternate exterior angles are equal.The pairs of alternate interior angles are equal.

Given:

<1 = 7y -20

<2 = 5x - 38

<3 = 90

exterior angle = 3x -4

Using alternate interior angle

5x - 38 = 3x-4

2x = 34

x=17

So, <2 = (5(17)-38))

<2 =47

Using angle sum property

90°+47°+(7y-20)=180°

7y-20=43°

y=9

Hence, the value of x is 17 and y is 9.
