Answer 1

Answer:

x=12

Step-by-step explanation:

180 - 6x - 6x - 3x

180 - 15x

180 = 15x

180 / 15 = x

x = 12

Answer 2

6x + 6x + 3x = 180

180= 6x + 6x + 3x

180= 15x

x= 180/15

x= 12

Answer:

Step-by-step explanation:

You would do something called KCF Keep, Change, and Flip.

You would keep the 7 1/2 and change the divided sign to multiplying sign and flip the 3/4 so its a 4/3 and then multiply it.

15/6 times 4/3. 15 x 4 = 60

2x3= 6

so I can be 60/6 but you would simplify and 6 goes into 60 10 times. so 10 is you answer

Standard to slope intercept form.

Answers

First bring the 2x to the other side:

2y = -2x + 16

Then divide by 2 to get y by itself, which the answer is

y = -x + 8

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

The equation 2x + 2y = 16 in slope-intercept form is

y = -x + 8.

Where slope = -1 and y-intercept is 8

What is an equation of a line?

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

We have the equation as,

2x + 2y = 16

We need to convert in the form of y = mx + c.

Subtract 2x on both sides.

2y = -2x + 16

Divide both sides by 2.

y = (-2x + 16) / 2

y = -x + 8

This is in the form of slope-intercept form.

Where slope = -1 and y-intercept is 8

Thus,

The equation 2x + 2y = 16 in slope-intercept form is

y = -x + 8.

Where slope = -1 and y-intercept is 8

Solve for f
-f + 2+ 4f = 8 - 3f

Answers

Answer:

f = 1

Step-by-step explanation:

-f + 2 + 4f = 8 - 3f

First, I'll add like terms.

2 + 3f = 8 - 3f

Then, I'll add 3f on both sides.

2 + 6f = 8

Next, I'll subtract 2 on both sides.

6f = 6

Finally, I'll divide 6 on both sides.

f = 1

Therefore, f = 1.

A cyclist rode 4.5 miles in 0.4 hours. How fast was the cyclist going in miles per hour

Answers

Speed =3.75÷0.3=12.5 miles per hour.

2) Speed = 12.5 miles per hour, Distance = 4.5 miles .

Time = Distance ÷Speed.

Time = 4.5÷12.5=0.36 hours.

Write an equation for a line that is parallel to y = -3x – 5 that goes through the point (-1, 8)

Answers

Answer:

y = -3x +5

Step-by-step explanation:

Parallel means that both slopes are the same.

This gives us y = -3x + C so far.

To find the y-intercept, we need to get x to 0.

Since we know the point (-1, 8), we can plug the number in into our equation

y = -3x + C.

8 = -3(-1) + C

8 = 3 + C

8 - 3 = C

5 = C or C = 5.

Now plug in C into our unsolved equation to get y = -3x +5.

19/36 - ⅜ =???????????????????????????

Answers

Answer:

1936−3/8=11/72

Step-by-step explanation:

19/36−38=?

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(19/36, 3/8) = 72

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(19/36×22)−(38×99)=?

Complete the multiplication and the equation becomes

38/72−27/72=?

The two fractions now have like denominators so you can subtract the numerators.

Then:

38−27/72=117/2

This fraction cannot be reduced.

Therefore:

1936−38=11/72

(Some of the numbers might be a fraction)

This is another challenging questionnn yayy All over the world, animal habitats bump up against human development. Where these two worlds collide, animals almost never farewell. Highways, where humans speed by large tracts of natural habitat like missiles of doom, are especially dangerous for wild creatures. They can also be deadly, not just for individual animals but for entire species. The Florida panther, for example, has such a low population that each time one is killed on a highway, it is a catastrophic loss.There is hope, however, in a new way of helping animals cross through highway areas unharmed. Wildlife overpasses give animals a way to cross highways without risking their lives. These look and work like bridges but are usually covered with grass and trees that make animals like deer feel welcome. The cars drive through a tunnel under the bridges. Fences along the top edges keep the animals safe.These overpasses also connect habitats, so along with deer, the coyotes who hunt them can cross. This allows both species to have a larger range, which also helps their long-term survival. To the animals in these habitats, the overpasses may be like an extra safety net that helps them survive a drought. The bridges are especially important for animals that migrate. For centuries, animals like elk and buffalo migrated on trails that still, now, lead right up to the edges of major highways. With the help of these bridges, migrating animals can still follow their long-used paths unharmed.In some cases, these overpasses benefit humans directly as well. In these cases, the overpasses are part of green space or parks that people use for cycling, backpacking, or jogging. The overpasses give humans access to areas they may not have been able to see but also provide safety for animals.The next time you are traveling on a highway, keep a lookout for a wildlife passage. With attention to how our lives affect the natural world, we can find clever solutions, like wildlife passages, that help animals and improve our lives, too.Extra! Extra!Not all wildlife accommodations for highways are overpasses. In some cases, certain species are so important that underpasses or underground tunnels are built. In Florida, two such underpasses help turtles, snakes, and alligators that often migrate from one body of water to another. Since these creatures do not have much speed, crossing a highway for them is even more deadly than it is for swift animals like deer. Working as a large funnel, these underpasses usually require a barricade or fence alongside the highway that forces animals toward a tunnel. Aquatic turtles especially benefit from these tunnels as they lay eggs in holes dug in dry ground, away from the lake they live in.Read this sentence from the text: In some cases these overpasses benefit humans directly as well.What is the purpose of this line in the essay?(options are below) The writer wants to add a sentence after sentence to provide factual support for the introductory claim and focus the audience on the argument of the passage.
