Answers

Answer 1

Answer:

#1. 3/8 and #2. 27/35

Step-by-step explanation:

3/4 - 3/8 change to 6/8 - 3/8 = 3/8 can not reduce

2/7 + 2/5 change to 10/35 + 17/35 = 27/35 can not reduce

Answer 2

How does x = 0.7x + 24 equal 80?

Answers

Answer:

x=0.7x+24

We move all terms to the left:

x-(0.7x+24)=0

We get rid of parentheses

x-0.7x-24=0

We add all the numbers together, and all the variables

0.3x-24=0

We move all terms containing x to the left, all other terms to the right

0.3x=24

x=24/0.3

x=80

And that's how you get 80

Step-by-step explanation:

i hope this helps.    :)

Answer: x = 80

Step-by-step explanation:

80 - 24 = 56

56 divided by 0.7 = 80

Answer:

...............

Step-by-step explanation:

0.8 = 0.5x

Solve for x

Please show steps thanks so much

Answers

If I’m not mistaken, to solve for x you have to get it by itself so you need to divide 0.5 from both sides:

0.8/ 0.5 = 0.5x/ 0.5

Cross out the 0.5’s on the right because they cancel out and you will end up with:

0.8/ 0.5 = x

All you have to do then is divide 0.8 by 0.5 and you get:

1.6 = x


If X-1 = 8, what justifies x - 1 = 16?

A quart of milk costs $1.89. What is the total cost for 20 quarts of milk?

Answers

To do this problem, you have to multiply the number of one quart of milk by twenty to get the total cost. So, you would do 1.89 x 20, which equals 37.8. So, the total cost would be $37.80 :)

Solve the equation for y. Type out your steps to solve this problem as you are showing your work:
7(y + 3) = 5y + 8

Answers

Answer:

-13/2

Step-by-step explanation:

7(y+3)=5y+8

7y+21=5y+8

7y-5y+21=8

2y+21=8

2y=8-21

2y=-13

y=-13/2

Answer:

y = -6.5

Step-by-step explanation:

simplify: 7y+21=5y+8

put like-terms together and simplify: 2y=-13

(like-terms: 7y-5y=8-21)

divide both sides by 2: y=-6.5

What is the perimeter of the figure shown below?

Answers

Answer:

D. 6x-14

Step-by-step explanation:

So first we would do 3x^2+3x^2-5x^2

That would all cancel out so that would be 0.

Next we would do 3x-4x+7x, this would equal to 6x

Finally we would do -4-8-2, this would be equal to -14

Then the equation would be 6x-14

All you have to do is combine like terms.

Two streets form an intersection. C and D are supplementary
angles. If the measure of C is 140° and the measure of D is
two times the value of x, what is the value of x?

Answers

Answer:

20degrees

Step-by-step explanation:

The sum of angle C and D is 180 degrees since they are supplementary

Given

m<C = 140 degrees

m<D = 2x

Taking the sum and equating to 180

140 + 2x = 180

2x = 180-140

2x = 40

x = 40/2

x = 20 degrees

Hence the value of x is 20degrees

There are 14 girls and 12 boys in a class. What is the ratio of girls to students?

Answers

Answer:

7:13

Step-by-step explanation:

There are 14 girls and 12 boys, so there are 26 students in total. Since we are looking for the ratio of girls to students, the ratio will be 14:26. To simplify it, we will divide 14 and 26 by their greatest common factor: 2. We will get the ratio of 7:13.

Find the value of each variable pls help for #10!!!

Answers

Remember that all triangles add up to 180. The triangle has congruent markings, therefore our equation will look like this:

11x-65+11x-65+29=180
Combine like terms.
22x-101=180
Add 101 to both sides.
22x = 281
Divide both sides by 22.
x = 12.77

The Martin family has three children. One is in elementary school, one is in middle school, and one is in high school. They are moving and would like to
live at a location that is the same distance from each of the three schools. They have mapped the schools in a coordinate plane. Determine the
coordinates of the best location that will be equidistant from all three schools.

Answers

Answer:

Answer is 1/2,-1 1/2

Step-by-step explanation:

The coordinates of the best location that will be equidistant from all three schools is; (-0.085, -2.232).

What is circumcenter of a triangle?

The circumcenter of a triangle is defined as the point where the perpendicular bisectors of the sides of that particular triangle intersect. In other words, the point of concurrency of the bisector of the sides of a triangle is called the circumcenter.

The coordinates of the 3 points that form a triangle attached in the image are;

A(-4, -2), B(0, 3), C(5, -1)

Since the distances to the circumcenter O from the vertices are all equal.

Then; AO = BO = CO.

From the first equality, we have AO² = BO²

(x + 4)² + (y + 2)² = (x - 0)² + (y - 3)²

⇒ 8x + 16 + 4y + 16 = – 6y + 9

⇒ 8x + 10y = -23   ---(1)

​Similarly, from the second equality, we have BO² = CO²

(x - 0)² + (y - 3)² = (x - 5)² + (y + 1)²

⇒ – 6y + 9 = -10x + 25 + 2y + 1

⇒ 10x - 8y = 17   ----(2)

Solving eq 1 and 2 simultaneously gives;

x = -0.085

y = -2.232

Therefore, the coordinates of the best location that will be equidistant from all three schools is; (-0.085, -2.232).

so from how i’m understanding it, it would be 12(90) + 20(121).

so 12 x 90 is 1080. so that’s already a good amt, but then 20 x 121 is 2420. now if we add those together,

Both effectively changed the popular opinion about emotional issues for their countries and brought in a wave of change that was long overdue. But the practice of non-violent protest, or civil disobedience, started long before either Gandhi or King. It began with a quiet, shy poet who is best known for writing a lot about a pond. Henry David Thoreau lived from 1817 until 1862, mainly in the area of Concord, Massachusetts. The issue that would tear the country apart in the 1860s had already begun dividing the nation. Thoreau was only 14 when Nat Turner led the slave rebellion in Virginia and was later hanged. In his late 20s, Thoreau began speaking against slavery in public, echoing the voices of freedmen like Frederick Douglass and Lewis Hayden. Thoreau believed that a government that supported slavery was corrupt and immoral. He was also deeply suspicious of government. For these and other reasons, Thoreau refused to pay his poll tax for a number of years. The poll tax was a legal tax owed by every person. It was basically a tax on one's body. After not paying for years, he was at last arrested. He spent only one night in jail, however, as a relative paid the tax for him. He was reportedly furious that any tax was paid on his behalf. It was this experience that Thoreau wrote about in an essay called "Civil Disobedience." In this essay, he argued that being moral and just came before allegiance to government. He wrote If the machine of government is of such a nature that it requires you to be the agent of injustice to another, then, I say, break the law." He also felt that voting was not enough to ensure that the right thing be done. He wrote that "even voting for the right is doing nothing for it A wise man will not leave the right to the mercy of chance" He felt that one had a moral responsibility to resist unjust laws.
