12) x=25

Step-by-step explanation:

Mark Me Brainliest?

Answer: 1: x = 10, 2: x = 25

Step-by-step explanation:

Problem One:

3x + 10 = 5x - 10

10 = 2x - 10

20 = 2x

x = 10

In Problem Two the vertical angle theorem was used, this states angles created by two intersecting lines across from each other are congruent (equivalent).

75 = 3x

75/3 = 3x/3

25 = x

Answer:

(4373/2) - 15

Step-by-step explanation:

if you scored 4373 points, and your friend scored 15 less than half that amount, you should divide your total by 2, then subtract 15.

Answer:

D. 19 houses

Step-by-step explanation:

[tex]\frac{1}{8} +\frac{2}{5} =\frac{21}{40}[/tex]

[tex]1 - \frac{21}{40}=\frac{19}{40}[/tex]

Answer:

D.) 19 houses

Step-by-step explanation:

comany x: 1/8

Company y: 2/5

You need to find the common denominator(in this case is to 40)

1 x 5 = 5            2 x 8 = 16

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

8 x 5 = 40         5 x 8 = 40

5/40 + 16/40 = 21/40

40 - 21 = 19

SO answer is 19

Answer:

7/8

Answer:

(3,2)

Step-by-step explanation:

2x+5y=16

3x-5y=-1

Subtract 2x from the first equation

5y=16-2x

Substitute the given value of 5y into the equation

3x-(5y)=16

3x-(16-2x)=-1

Solve for x

3x-(16-2x)=-1

3x-16+2x=-1

5x-16=-1

5x=15

x=3

Substitute the given value of x into the equation

3x-5y=-1

3*3-5y=-1

Solve

3*3-5y=-1

9-5y=-1

-5y=-10

y=2

Answer:

0.3

Step-by-step explanation

The formula to find density is m/v=p

m=mass

v=volume

p=density

All we have to do is plug in 6g and 20cm^3

This will give us 6/20 which simplifies to 3/10

With this you can easily figure out that the decimal for 3/10 is 0.3

So the density of the ice is 0.3

Answer:

82 or 5.3

Step-by-step explanation:

As you know a whole triangle is 180° so if you subtract 16 from 180 you get 164 so then you just divide it by three and you get 54.3.

Or if that is wrong try dividing 16 into three and you get 5.3.

I'm really sorry if neither one of these are right!

Answer:

i believe the answer is 162 cubic inches

Step-by-step explanation:

as we know, the rectangles are conjoined but the easiest way to solve this is to separate them (so to speak) with that, let us pretend that we've cut them making two individual rectangles-

so rectangle one's dimensions are-

1, 8,9 (remember that the order the numbers are in is unimportant because the answer will still be the same no matter the order)

and rectangle two's dimensions are-

2,5,9

the formula for the volume of a rectangular prism is v=wlh

now we just need to plug in the information

rectangle one- v=1*8*9=72

rectangle two=2*9*5=90

now let us suppose we've re-conjoined the rectangular prisms-

(meaning we're going to add up the volumes for the total volume of the shape given in your problem)

72+90=162 cubic inches

good luck :)

The answer is 37.5. Hope this helps!!

The result is 300 divided by 8 equals 37.5.

So, when we divide 300 by 8, the quotient is 37, and there is a remainder of 4.

To divide 300 by 8, we need to understand the concept of division and perform the division operation step by step.

Division is the process of splitting a quantity into equal parts or groups. In this case, we want to divide 300 into 8 equal parts.

At first we divide the first digit of the dividend (300) by the divisor (8).

In this case, the first digit is 3.

3 ÷ 8 = 0 with a remainder of 3

Then, bring down the next digit of the dividend (0) and add it to the remainder from the previous step to form a new dividend.

The new dividend becomes 30.

We divide the first digit of the new dividend (30) by the divisor (8).

30 ÷ 8 = 3 with a remainder of 6

Then, bring down the next digit of the new dividend (0) and add it to the remainder from the previous step to form a new dividend.

The new dividend becomes 60.

We divide the first digit of the new dividend (60) by the divisor (8).

60 ÷ 8 = 7 with a remainder of 4

Then, bring down the next digit of the new dividend (0) and add it to the remainder from the previous step to form a new dividend. The new dividend becomes 40.

We divide the first digit of the new dividend (40) by the divisor (8).

40 ÷ 8 = 5 with no remainder

There are no more digits to bring down, so the division process is complete.

Now, we have the quotient and the remainder:

300 ÷ 8 = 37 with a remainder of 4

i.e. we get,

300 ÷ 8 = 37.5

So, 300 divided by 8 equals 37.5.

So, when we divide 300 by 8, the quotient is 37, and there is a remainder of 4.
