Mathematics

Vera_Pavlovna [14]3 years ago

Step-by-step explanation:

5x+2y=29

5x-2y=41

add the equations

10x=70

divide both sides by ten

x=7

substitute 7 in the first equation

5(7)+2y=29

simplify

35+2y=29

subtract 35 from both sides

2y=-6

simplify

y=-3 x=7

3x+2y=9

5x+2y=12

subtract the equations

-2x=-3

simplify

x=1.5

substitute

3(1.5)+2y=9

simplify

4.5+2y=9

subtract 4.5 from both sides

2y=4.5

simplify

y=2.25 x=1.5

5x+2y=-9

2x-3y=4

multiply first equation by three and second by two

15x+6y=-27

4x-6y=8

add equations

19x=-19

simplify

x=-1

substitute

15(-1)+6y=-27

simplify

-15+6y=-27

add 15 to both sides

6y=-12

simplify

y=-2 x=-1

HELP !!  The figure below is made from a rectangle and a triangle use the measurements shown below , find the area of the figure
Vika [28.1K]
The answer is 76. multiply 15 times 4 which is 60.
 and the triangle is the difference of the sides, so 19-15=4.
 so then multiply the base and height, this leaves 4x4 which is 16.
 then add the two. 60+ 16= 76
