X=14
Co- interior angles are supplementary
9x+14+3x-2=180
12x+12=180
12x=180-12
X=168/12
X=14
Y=9X+14 (vertically opposite angles are equal)
Y=9*14+14
Y=126+14
Y=140

Answer:

x=14

y=140

Step-by-step explanation:

Using (9x+14) + (3x-2) = 180, we can solve this equation.

First add like values giving you 12x+12=180. Then subtract 12 from both sides giving you 12x=168.

Then divide both sides by 12 giving you x=14.

Finally, just simply set 9x+14 equal to y and substitute x for 14. This gives you 140=y

Hope this helped

In the figure, if m∠ABD = 120º, then m∠ADC = ___

Darya [45]

Okay first, use the sin rule ( $\frac{SinA}{a} = \frac{SinB}{b}$
so $\frac{Sin120}{35} * 30 = SinB$
sin^-1 this and you get 47.928....this is angle ADB
and as it is on a straight line, 180 - this angle gets ADC
180 - 47.928.... = 132.07

Answer:

$\frac{1}{3}x+16=37$

63 Jelly Beans

Step-by-step explanation:

The unknown is the number of jelly beans originally in the bag or x

First he had x jelly beans

The he ate one-third of them

$\frac{1}{3}x$

He then ate 16 more jelly beans

$\frac{1}{3}x+16$

This was equal to 37 jelly beans

$\frac{1}{3}x+16=37$

This is the equation

Now solve for x

Subtract 16 from both sides

$\frac{1}{3}x=21$

Multiply both sides by 3

$x=63$

She had $3000. She spend 40% of the money in smart TV and 15% of the remainder on Game Set. (a) What % of the money had she left

Dovator [93]

Answer: She had left 54% of the money which is $1620.

Step-by-step explanation:

40% of $3000 = $1200

15% of $1200 = $180

$3000 - ($1200 + $180)

$3000 - $1380 = $1620

$1620 is the money she had left.

$1620 is 54% of $3000

She had 54% left of the money.

Hope that helped~!

£2200 is deposited in a bank paying 0.5% simple interest per annum. How much interest will have been paid after 18 years?

seraphim [82]

Answer:

The answer would be £198

principal (p) = 2200

Rate (R) = 0.5%

Time (T) = 18

Interest(I) = ?

Now,

or, Interest. = P×T×R/100

or, Interest = 2200×18×0.5/100

or, Interest = 19800/100

Hence, Interest = 198
