1/6x + 3/4y =4​

Answers

Answer:
y=5 5/9

Step-by-step explanation:
1/6(-1)+3/4y=4
-1/6=4-3/4y
-1/6-4=-3/4y
-4 1/6=-3/4y
4 1/6=3/4y
1/4y=1 7/18
y=1 7/18*4
y=5 5/9


Hey there!

1/6x + 3/4y = 4

1/6(-1) + 3/4y = 4

- 1/6 + 3/4y = 4

3/4y - 1/6 = 4

ADD 1/6 to BOTH SIDES

3/4y - 1/6 + 1/6 = 4 + 1/6

SIMPLIFY IT!
3/4y = 4 + 1/6

3/4y = 25/6

MULTIPLY 4/3 to BOTH SIDES

3/4y * 4/3 = 25/6 * 4/3

SIMPLIFY IT!
y = 25/6 * 4/3

y = 50/9

y = 5 5/9


Therefore, the answer should be:

y = 5 5/9

Answer:

C. the dollars per minute late

Step-by-step explanation:

In the question it says 0.50 represents the dollars charged per minute late.

Answer:

The answer would be A

Step-by-step explanation:

WARNING THIS MIGHT BE WRONG BUT WORTH A SHOT

I say "a" because if you look at the problem or equation given

10.50=0.50a+3

10.50 is for the amount of money the had to pay

0.50 is the cost for if they are late for pick-up

the 3 is for the base fee

the amount of mins would be times by 0.50 then that plus 3.

Which of the following statements is true?

Answers

Answer:

D

Step-by-step explanation:

Options A & B are multiplied by improper fractions. Therefore,

54 × (5/3) > 54 not < 54

28 × (3/2) > 28 not < 28

Option C should be 49 × (3/7) < 49 not > 49

Whole numbers multiplied by fractions should be smaller.

Hence, option D is the right answer.

Note: Try multiplying like this

(54×5)/3 _ 54

Answers

Answer:

2.5 cm

Step-by-step explanation:

Rectangle A    L x W = 40

                   

Rectangle B     L * W   = 1/2 (40)

                        8 * W = 20

                              W = 2.5 cm

Answer:

The width of B. is 2.5cm

Step-by-step explanation:

Rectangle A has 40cm^2 and a length of 8.

Rectangle B. has an area half of 40cm^2 which would be 20cm^2.

Area of B has an area of 20cm^2

Now we need to find the width of B.

All that we know is that B. has an area of 20cm and it has the same length as A, and that length is 8.

Everyone knows that you multiply the length by the width to find the area of a shape.

8 times something = 20

We can do that backward and divide 8 by 20 which is 2.5

To check this answer we multiply 2.5 by 8 which = 20

The width of rectangle B. is 2.5cm.

A salesman at a jewelry store gets paid 30% of the selling price of each piece of jewelry he sells. About how much will he get paid for selling a ring that costs $495?

Answers

Answer:

$148.50

Step-by-step explanation:

Concepts

To find <x% of y> or a certain percent of a number, you have to:

Convert the percent into a decimal (by moving the decimal point two place to the left. e.g. if the percent was 25%, it would be 0.25.)Multiply that decimal by the other number

Application

In this case, we're asked to find how much the salesman makes, knowing that makes 30% of price of the item he sells. We're given the price of one item as $495. Now, we have to multiply 30% by 495 by follow the two aforementioned steps.

Solution

Step 1: Convert 30% into a decimal

30%0.30

Step 2: Multiply 0.30 by 495.

Answer:

see below

Step-by-step explanation:

9/2= ?x1/2

As 9/2 is on the other side of the equal sign and you want to combine like terms, you divide 9/2 by 1/2

9/2 x 2/1

(Flip the second term)

Cancel out the 2's

9/1 x 1/1

This equals 9

I make 69832,420$ a month. How much do I make a day? How much do I make an hour?

Answers

Answer:

per day: approx. $2,327,747.3

per hour: approx. $96989.5

Step-by-step explanation:

(assuming the amount of money you make per month is $69,832,420)

Divide the given amount by 30 (or 31/28 if the specific month is given) for the amount of money made per day, since there are about 30 days in a month. Ans: $2,327,747.3 (cor. to the nearest tenth digit)

Further divide the amount by 24, since there are 24 hours in a day. Ans: $96989.5 (cor. to the nearest tenth digit)

1,530[tex]cm^{3}[/tex]

Step-by-step explanation:

The formula to find a the volume of a rectangular prism :

Volume (V) = length x height x width

Your image has two rectangular prism put together

First rectangular prism (on the left):

Volume (V) = length x height x width

length = 10cm

width = 9cm

height = 9cm

Volume (V) = 10cm x 9cm x 9cm

Volume (V) = 810[tex]cm^{2}[/tex]

Second rectangular prism (on the right):

Volume (V) = length x height x width

length = 18cm

width = 10cm

height = 4cm

Volume (V) = 18cm x 10cm x 4cm

Volume (V) = 720[tex]cm^{2}[/tex]

Now to get the total of the figure.

Add both the first and second rectangular prism volume:

Volume (V) = 810[tex]cm^{2}[/tex]

Volume (V) = 720[tex]cm^{2}[/tex]

720 + 810 = 1530
