Answer:

x = 18 , y= 11.

Step-by-step explanation:

Given : figure .

To find: solve for x and y .

Solution: We have given figure

92° and (6x-16)° are vertical opposite angles .

Vertical opposite angles: S hare the same Vertex (corner point).

Vertical opposite angles are always equals.

92 = 6x - 16.

On adding both sides by 16.

92 + 16 = 6x .

108 = 6x .

On dividing both sides by 6

x = 18.

Now , angle 92 and 8y are linear pair angle because it formed at a line

Sum of Linear pair angles are 180 degree.

92 + 8y=  180.

On subtracting both sides by 92.

8 y = 180 - 92.

8 y = 88.

On dividing both sides by 8

y =11 .

Therefore, x = 18 , y= 11.

Answer:

y = 11, x = 76/6

Step-by-step explanation:

We will start by finding y

92 + 8y = 180 we know this because the angle degree of one line is 180 you can just do simple elimination to solve this

92+ 8y = 180 subtract 92 from both sides

8y = 88 then divide both sides by 8 and you get

y = 11

Now for x we know the blank angle is equal to 88 because of vertical angles

so now it is 88 + ( 6x - 16) = 180 again we do elimination

88 + 6x - 16 = 180 subtract 88 from both sides and you get

6x - 16 = 92 then subtract 16

6x = 76 then divide both sides by 6 and get

x = \frac{76}{6}

hope this helps :)

mihalych1998 [28]

Answer:

You invested $22,000 in two accounts paying 3% and 5% annual interest, respectively. If the total interest earned for the year was $980, how much was invested at each rate?

Step-by-step explanation:

let x=amt invested at 3% rate of interest.

22000-x=amt invested at 5% rate of interest.  

.03x+.05(22000-x)=980

.03x+1100-.05x=980

.02x=120

x=6000

22000-x=16000

amt invested at 3% rate of interest=$6,000

amt invested at 5% rate of interest=$16,000

I have a stamp collection. 70% of my stamps are Canadian and 30% are international. I have 500 more Canadian stamps than interna
shutvik [7]

Answer: N= 375, C= 875

Step-by-step explanation:  Let Canadian stamps=C

Let International stamps=N

C=875     and        N=375

 

C - 500=N,  .70(N + C) =C

Solve the following system:

{C-500 = N |     (equation 1)

0.7 (C+N) = C |     (equation 2)

Express the system in standard form:

{-N+C = 500 |     (equation 1)

0.7 N-0.3 C = 0 |     (equation 2)

Add 0.7 × (equation 1) to equation 2:

{-N+C = 500 |     (equation 1)

0 N+0.4 C = 350 |     (equation 2)

Divide equation 2 by 0.4:

{-N+C = 500 |     (equation 1)

0. N+C = 875. |     (equation 2)

Subtract equation 2 from equation 1:

{-N+0 C = -375. |     (equation 1)

0 N+C = 875. |     (equation 2)

Multiply equation 1 by -1:

{N+0 C = 375. |     (equation 1)

0 N+C = 875. |     (equation 2)

Collect results:

Answer: |  N = 375        and             C=875
