Fill in the other coordinate for the line 2x - 5y = 11: (4, )

enot [183]

2x - 5y = 11. (4, a). x = 4, y = a

Substituting into 2x - 5y = 11

2(4) - 5(a) = 11

8 - 5a = 11

-5a = 11 - 8

-5a = 3

a = 3/-5 = -3/5 =- 0.6

Other coordinate = -3/5 = -0.6

La suma de las edades de unos gemelos y unos trillizos es 150 años si se intercambian las edades la nueva suma es 120 años ¿ cua

julsineya [31]

Answer:

The age of triplets is 42 years old

Step-by-step explanation:

The question in English is

The sum of the ages of twins and triplets is 150 years if the ages are exchanged the new sum is 120 years. What is the age of triplets?

Let

x -----> twins age

y ----> triplets age

we know that

2x+3y=150 ------> equation A

2y+3x=120 -----> equation B

Solve the system by graphing

The intersection point both graphs is the solution of the system

The solution is the point (12,42)

see the attached figure

therefore

The age of triplets is 42 years old

Armen received $2000 as an interest for term deposit of 2 years. How much money did he deposit, if the annual interest was 8%?

suter [353]

Answer: $12,500

Step-by-step explanation:

We want to find how much he deposited annually, so we divide 2000 by 2 to get 1000 for 1 year. 1000 is 8 percent of what we need to find, so if we multiply 1000 by 100/8, we get $12,500 as our answer.
