Answer:

10°

Step-by-step explanation:

5x + 2x + 20° = 90° { Being complementary angles }

7x = 90° - 20°

7x = 70°

x = 70° / 7

x = 10°

X+2y= -14 x and y intercept
Ira Lisetskai [31]

Answer:

x intercept (-14,0)

y intercept (0,-7)

Step-by-step explanation:

x+2y= -14

To find the x intercept set y =0 and solve for x

x + 2(0) = -14

x = -14

To find the y intercept set x =0 and solve for y

0+2y = -14

2y = -14

2y/2 = -14/2

y = -7

0.2(6x+1)/3.6 = 0.5x/9 please include work
sergey [27]

0.2(6x+1)/3.6=0.5x/9


We move all terms to the left:


0.2(6x+1)/3.6-(0.5x/9)=0


We add all the numbers together, and all the variables


0.2(6x+1)/3.6-(+0.5x/9)=0


We get rid of parentheses


0.2(6x+1)/3.6-0.5x/9=0


We calculate fractions


There is no solution for this equation
