1 answer:

6 0

You start of with a number, ( this number can be any number) so think of it as an unknown number. the number shall be denoted as x so you have x you want triple the number 3x you also want to double the number 2x you want the difference so you subtract these two terms 3x-2x

What is 7x+5y=-12-7x−7y=14

kramer

Answer:

x=1/14 and y=1/12

Step-by-step explanation:

7x+5y+12+7x+7y=14

⇒14x+12y=2

and set x and y in 0

then you will have 14*(1/7)=2 and 12*(1*6)=2

and you want somthing that makes x + y =2

so you sett 14*x=1 and 12*y=1

that is if i did noy misunderstanding the question

The distance between two locations, A and B is calculated using a third location C at a distance of 15 miles from

Rufina [12.5K]

<h3>Answer: approximately 6.3 miles</h3>

=================================================

Explanation:

See the diagram below. The two given angles B = 105 and C = 20 are used to help find angle A

A+B+C = 180

A+105+20 = 180

A+125 = 180

A = 180-125

A = 55

Then we use the law of sines to find the side length c

sin(A)/a = sin(C)/c

sin(55)/15 = sin(20)/c

c*sin(55) = 15*sin(20) ... cross multiply

c = 15*sin(20)/sin(55) .... divided both sides by sin(55)

c = 6.26294249724791 .... value is approximate

c = 6.3 ....... rounding to one decimal place
