What is the answer to this? Brainlest if you have a step by step.

Step-by-step explanation:

2x-15y=6---->1

x-6y=-1

x=-1+6y----->2

use substitution

substitute 2 in 1

2(-1+6y)-15y=6

-2+12y-15y=6

-3y=6+2

-3y=8

y=-8/3

x=1+6(-8/3)

x=1+(-16)

x=-15

Answer:

9 ÷ 4

Step-by-step explanation:

Answer:

m∠L + m∠M = 90°

sin(L) = 0.66913

sin(M) = 0.74314

Step-by-step explanation:

The sum of the two angles is ...

 m∠L + m∠M = 42° +48° = 90°

__

A calculator can show you the sines of these angles.

 sin(42°) ≈ 0.66913

 sin(48°) ≈ 0.74314

_____

The two acute angles of a right triangle always have a sum of 90°.

Answer:

its all true

Step-by-step explanation:

A B C D are true

Answer:

True: A dilation with a scale factor of 1/3 is a reduction.

False: A dilation with a scale factor of 2 is a reduction.

Step-by-step explanation:

A dilation with a scale factor between 0 and 1 is a reduction because the image will decrease in size.

On the other hand, a dilation with a scale factor greater than 1 is an enlargement, where the image increases in size.

So, the statement that a dilation with a 1/3 scale factor is a reduction is true.

The other statement is false, which says a dilation with a scale factor of 2 is a reduction.

Answer:

The third one

Step-by-step explanation:

To set a new record, the new distance would have to be greater than 518cm. In the third graph the circle is open indicating 518 is not included, and the ray extend towards numbers greater than 518.

Answer:

  34

Step-by-step explanation:

In order to divide some multiple of 15 chocolate bars evenly by 21, the number of bars must be a multiple of the LCM of 15 and 21, which is 105. That number is 7 times 15, indicating the number of boys in the class must be a multiple of 7. The only number between 30-20 = 10 and 40-20 = 20 that is a multiple of 7 is 14.

There must be 14 boys in the class, so 34 students in total.

__

The boys brought a total of 210 chocolate bars, so each girl and the teacher received 10 of them.

Answer:

  x = 27°

Step-by-step explanation:

Each exterior angle is equal to the  sum of the remote interior angles.

  6x = 90° +(180° -4x)

  10x = 270° . . . . . add 4x

  x = 27° . . . . . . . . divide by 10

_____

Check

6x = 162°, so the adjacent interior angle of the triangle is 180° -162° = 18°.

4x = 108°, so the adjacent interior angle of the triangle is 180° -108° = 72°.

The interior angles of the triangle are complementary, as they should be.

  18° +72° = 90°

i have the same question now

Answer:

-18y - 18

Step-by-step explanation:

The -2 needs to be distributed into both values in the parenthesis. This will make the equation -8y - 10y - 18. Then, you put the like terms together. This will result in the final equation, -18y - 18

Answer:

I believe the answer you're looking for is 3.16227766 x 2.828427125=

If that's not what you looking for the answer to square root of 10 times square root of 8 equals 8.94427191

Answer:

About 79.2%

Step-by-step explanation:

1,067/1,348= 0.7915

in order to get a percent you move the decimal point to the right 2

therefore it equals  79.15% (which you can round to 79.2%)

is you want a whole number it would be About 79%

Answer:

y= -4x + 1

Step-by-step explanation:

I hope this helps :)

Answer: y=-4x+1

Step-by-step explanation:

Answer: B

Step-by-step explanation: Step 1: Subtract 3x from both sides.

4x−5−3x=3x−10−3x

x−5=−10

Step 2: Add 5 to both sides.

x−5+5=−10+5

x=−5

hope this help

Answer:

B. x-5  

Step-by-step explanation:

Step 1: Subtract 3x from both sides.

4x−5−3x=3x−10−3x

x−5=−10

Step 2: Add 5 to both sides.

x−5+5=−10+5

x=−5

Hope this helped :)

Answer:

3 1/2

Step-by-step explanation:

You can do 1 1/3 + 3/4 + 2/3 + 3/4 which equals 3 6/12.

Now in fraction problems, they always want it in the simplest form, so the simplest form of 3 6/12 is 3 1/2.

Your answer is 3 1/2.

Answer:

3 6/12

Step-by-step explanation:

1 1/3 goes to 1 4/12

2/3 goes to 8/12

3/4 goes to 9/12

3/4 goes to 9/12 (again)

1 4/12 + 8/12= 2

9/12 + 9/12= 1 6/12

1 6/12 + 2 = 3 6/12

Answer:

50d * 0.35m

Step-by-step explanation:

so I don't normally do it like this it would normally be 50 * 0.35x.  but the days also had a fee unless she doesn't have it for 2 days and only has it one but d is the days she has it and m is the miles driven the * is times

you would have to find out the days she has it unless you don't have that is would be the answer above (if I am wrong I'm sorry)
