Measure of a verticle angle is 7x+182 and another angle is 9x+194 solve for x

1 answer:

4 0

The measures of 2 vertical angles are always equal, so we have:

7x+182=9x+192.

Rearranging, we have 182-192=9x-7x, which simplifies to -12=2x.

Thus, x=-6.

This means that the angles are:

i) 7x+182=7(-6)+182=182-42= 140(degrees).

ii) <span>9x+194=9(-6)+194=194-54=140 (degrees, as expected.)

Answer: x=-6</span>

4/9+(x-1)=28/9-(x-7x)+1

k0ka [10]

4/9 + (x-1) = 28/9 - (x-7x) + 1

4/9 + x - 1 = 28/9 - x + 7x + 1

-5/9 + x = 37/9 + 6x

-5x = 42/9

-5x = 4.6 (repeating 6)

x = -0.93 (repeating 3)

Hope this helps! ;)

Answer:

The numbers are 10 and 5

Step-by-step explanation:

x+y=15

(1/x)+(1/y)=(3/10)

(1/(15-y))+(1/y)=(3/10)

x=10, y=5
