Answer:

B) y = -4

Step-by-step explanation:

When rearranging an equation we divide, multiply, subsract, add the same things to both sides of the equation.

So here we would - 4 from both sides to give:

y + 4 - 4 = 0 - 4

This would simplify to:

y = -4

Answer:

 10x+7y = -8

Step-by-step explanation:

Standard form is Ax + By + C = 0 or Ax + By = C.

The first step is everything is multipled by 7, witch gives you 7y=-10x-8.

To solve that, 10x to both sides must be added, to get 10x+7y-8

Explanation:

First we multiply everything by 7 to clear out the denominators.

We get to 7y = -10x - 8

Then add 10x to both sides to arrive at 10x+7y = -8

Standard form is Ax+By = C where A,B,C are integers

In this case we have: A = 10, B = 7, C = -8

Some math textbooks insist that A > 0.

Answer:

= 1.044

Step-by-step explanation:

-------------------------------

Answer:

0.36 x 2.9 = 1.044

Step-by-step explanation:

Using proportions, it is found that Judy and Amna will be 2420 ft apart after 8 minutes.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

They run in opposite directions, at speeds of 180 feet per minute and 120 feet per minute, respectively, hence each minute they get 180 + 120 = 300 feet apart.

They already are 20 feet apart, so they will need to get more 2420 - 20 = 2400 ft apart. Hence:

1 minute - 300 ft apart.

x minutes - 2400 ft apart.

Applying cross multiplication:

300x = 2400

x = 8.

Judy and Amna will be 2420 ft apart after 8 minutes.

Answer:

5 + x + 5 + x + x

Step-by-step explanation:

We are given 4 expressions and we have to determine which expressions shows a sum of five terms.

We use the process of elimination:

5(x + 5)

=5x+25  (distributing 5)

This contains sum of only two terms, eliminate.

5x

It contains only 1 term, eliminate.

5 + x + 5 + x + x

It contains 5 terms 5,x,5,x and x, KEEP!

5.

Only contains 1 term, eliminate.

With this said, were left with:

5 + x + 5 + x + x

Which is the correct answer! :)

Answer:

A

Step-by-step explanation:

there is not much more to say.

the point where actually all 3 line bisectors intersect, is also called the "circumcenter". I guess you understand what that means : it is the center of the circle circumscribing the whole triangle (passing through all 3 corners/vertices).

once you find that point with 2 line bisectors, there is no need to construct the third - it WILL intersect the others at the same point.

Answer:

A

Step-by-step explanation:

Answer:

Step-by-step explanation:

Remark

The angles can measure

x + 2x + 3x

The total must be 180 degrees because all triangles have 180 degrees

Equation

x + 2x + 3x = 180          Combine

6x = 180                        Divide by 6

6x/6 = 180/6

x = 30

1x = 30

2x = 60

3x = 3*30 = 90

A right angle triangle has 90 degrees.

Answer:

the answer to your question is 9.73

Answer:

A

Step-by-step explanation:

Because according to my calculations there are supposed to be 5 digits and for the answers for the question A is the only letter with an answer with 5 digits.

My answer was 9.7325(even though the answers is different they still have the same number of digits) and for A it is 9.7324 which is another 5 digits.

Here is why I got 5 digits.

4.0125

5.7200

_______

When we add these we have to add 0er's to 5.72 because it doesn't have enough digits to add so you add zero's to it.

So 5 +0=5  2 +0=2  1 +2=3  0 +7=7  and for our last number 4 + 5=9 and so our answer is ?

9.7325

and the 9 = 1 digit 7=2 digit 3= 3 digits 2= 4 digits and last 5 = 5 digits.

Hope this helps have a great day:)

Answer:

Circle B has a larger circumference.

Step-by-step explanation:

Circumference of a circle is the diameter times pi.

C = pi•d

Circle B has radius 5, so its diameter is 10. Circle A has diameter of 9. A larger diameter will give a larger circumference.

C_circle A = 9pi

~= 28

While,

C_circle B = 10pi

~= 31

Circle B's circumference is about 3 cm larger. More accurately it's 1pi larger.

Answer:

none of these

Step-by-step explanation:

none of these is the correct answer because if this is pemdas it would be 24.818

and if it is not pemdas it would still be 3.818.

The way pemdas would be solved is 62 divided by 22 first which is 2.818

and then 2.818 + 22 which= 24.818.

But if your just doing it in order and it isn't pemdas than you would do 22 + 62 which=84 and then 84 divided by 22=3.818

So your answers are wrong I wanted to let you know that is there an option od none of theres or is there more to the question I can help you with.

I hope I can help and that this helps have a awesome day:)

Answer:

1362

Step-by-step explanation:

so

A=1600(1-0.02)^8

A = total population after 8 years

1600 = initial amount of people

0.02 = percent in decimal

8 = years after 2000

1- = decay

Answer:

principle (p)=Rs1400

Rate(R)=6.5

time(T)=3

we know that

I=P×I×T/100

=1400×6.5×3/100

=273

therefore the simple interest earned is Rs273
