solve the following system using substitution x+4y=21 4x-y=16

Answers

x+4y=21
4x-y=16

Isolate one of the variables
x + 4y = 21
subtract 4y from both sides
x = -4y + 21

Plug that into the other equation
4x - y = 16
4(-4y + 21) - y = 16
-16y + 84 - y = 16
combine like terms
-17y + 84 = 16
subtract 84 from both sides
-17y = -68
divide both sides by -17
y = 4

Plug that into the equation
x+4y=21
x + 4(4) = 21
x + 16 = 21
subtract 16 from both sides
x = 5

Karina read a total of 20 2/4 pages in her science and social studies books combined she read 12 3/4 pages in her science book how many pages did she read in her social studies book?

Answers

7 3/4 pages in her social studies book

Final answer:

To find out how many pages Karina read in her social studies book, you subtract the number of pages read in the science book from the total pages read. After doing the math, Karina read 8 1/4 pages in her social studies book.

Explanation:

Karina read a total of 20 2/4 pages in both her science and social studies books combined. It is mentioned that she read 12 3/4 pages in her science book. To find out how many pages she read in her social studies book, one must subtract the pages read in the science book from the total pages read.

The subtraction of mixed numbers involves the following steps:

First, make sure the fractions have the same denominator.

Then, subtract the fractions.

If necessary, borrow from the whole number and reduce the fractions further.

Finally, subtract the whole numbers.

In this case:

Total pages - Science book pages = Social Studies book pages

20 2/4 - 12 3/4 = 7 5/4 or 8 1/4 pages (since 5/4 is equal to 1 and 1/4).

Therefore, Karina read 8 1/4 pages in her social studies book.

Container A can hold 9 cups of liquid. container B can hold 5 pints of liquid. Container c can hold 2 quarts of liquid. Whice container has the greatest capacity? Explain

Answers

Hello!

1 cup = 0.5 pints

1 cup = 0.25 quarts

That means that 9 cups are equivalent to 4.5 pints and 2.25 quarts of liquid.

1 pint = 2 cups

1 pint = 0.5 quarts

That means that 5 pints are equivalent to 10 cups and 2.5 quarts of liquid.

1 quart = 4 cups

1 quart = 2 pints

That means that 2 quarts are equivalent to 8 cups and 4 pints of liquid.

FINAL ANSWER:

Judging by our calculations, Container B has the greatest capacity.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

If there are four colors of fireworks (orange, green, purple, and blue), then the number of different orders in which they can appear can be found by calculating the number of permutations of four objects, which is:

4! = 4 x 3 x 2 x 1 = 24

Therefore,

There are 24 different orders in which the different colors of fireworks can appear.

4,960 - 24 = 4,936

4,936 / 8 = 617

There are 617 bags of tomatoes.

the grocer has 40 crates of tomatoes with 124 tomatoes in each crater
124*40=4960 tomatoes
24 are rotten

Keisha's boat has a top speed of 9 miles per hour in still water. While traveling on a river at top speed, she went 10 miles upstream in the same amount of time she went 20 miles downstream. Find the rate of the river current.

Answers

If she went 10 miles upstream in the same time as she went 20 miles downstream, that means the downstream speed is twice the upstream speed.

The speed is still water is 9 mph.
The speed of the current is c.
Going downstream, the current adds speed, so the sped downstream is 9 + c.
The speed upstream is 9 - c.
9 + c is twice 9 - c.

9 + c = 2(9 - c)

9 + c = 18 - 2c

3c = 9

c = 3

Answer: The speed of the current is 3 mph.

Check:
9 + c = 12
9 - c = 6
By taking into the account the speed of the current, the downstream speed, 12 mph, is indeed twice the upstream sped, 6 mph.

an artist painted a 6 foot tall painting, then decide to also create a smaller version. if she uses a scale of 4 inches=1.5 feet, what will be the height of the smaller painting

Answers

let
x----------------- > the height of the smaller painting
y-----------------> the height of the tall painting-----------> 6 ft

the scale factor is-------------- > x/y
(x/y)=(4 in)/(1.5 ft)
x=y*[(4 in)/(1.5 ft)]-------> 6*(4 in)/(1.5 ft)=16 in

the answer is x=16 in

Final answer:

To determine the height of the smaller version of the painting using the scale of 4 inches = 1.5 feet, we first convert the original height to inches (6 feet = 72 inches) and then use a proportion to find that the height of the smaller painting is 16 inches.

Explanation:

The student's question involves using a scale to determine the height of a smaller version of a painting. The scale given is 4 inches = 1.5 feet. To begin, we convert the original height of the painting from feet to inches since the scale is in inches. The original height of 6 feet is equivalent to 72 inches (because 1 foot is equal to 12 inches).

Next, we set up a proportion using the scale:

4 inches / 1.5 feet = x inches / 6 feet

Now we solve for x, which represents the height of the smaller painting in inches:

4 / 1.5 = x / 6

4 / 1.5 * 6 = x

x = 4 * 6 / 1.5

x = 24 / 1.5

x = 16 inches

Thus, the height of the smaller version of the painting will be 16 inches.

An observer in a lighthouse 350 feet above sea level observes two ships directly offshore. The angles of depression to the ships are β = 7° and θ = 10.5° (see figure). How far apart are the ships? (Round your answer to one decimal place.) ft

Answers

The ships are 21.5 feet apart.

We have,

Let's denote the distance between the observer and Ship 1 as x and the distance between the observer and Ship 2 as y.

Using the angles of depression, we can establish the following relationships:

tan(β) = x / 350

tan(θ) = y / 350

We need to find the distance between the ships, which is the difference between x and y.

To find x and y, we can rearrange the equations as follows:

x = 350 * tan(β)

y = 350 * tan(θ)

Now, we can calculate the distances x and y using the given angles of depression:

x = 350 * tan(7°)

x ≈ 42.9 feet

y = 350 * tan(10.5°)

y ≈ 64.4 feet

The distance between the ships is the difference between x and y:

Distance = y - x

Distance ≈ 64.4 - 42.9

Distance ≈ 21.5 feet

Therefore,

The ships are 21.5 feet apart.

An airplane is flying at an altitude of 10,000 feet when it receives clearance to land at the airport. The angle of depression from the airplane to the airport is 4o. What is the horizontal (ground distance) from the airport to the airplane's position?

Answers

Since we know that The angle of depression from the airplane to the airport is 40°, and its altitude is 10000 feet, we can create a right triangle using the horizontal of the plane, the angle of depression, and the altitude as one of the legs of our right triangle. the horizontal (ground distance) from the airport to the airplane's will be the same as the adjacent leg of our depression angle. To find the adjacent leg we'll need a trig function that relates our leg with the depression angle and the opposite leg. That trig function is tangent. So lets set up an equation and solve it to find our distance:
[tex]tan(40)= \frac{10000}{leg} [/tex]
[tex]leg= \frac{10000}{tan(40)} [/tex]
[tex]leg=11917.54[/tex]

We can conclude that the horizontal (ground distance) from the airport to the airplane's position is 11,917.54 feet.
