3x + 4y = 16 (3x + 4y)^2 = 16^2 = 256 9x^2 + 16y^2 + 24xy = 256 9x^2 + 16y^2 = 256 - 24xy = 256 ... 9x²+16y²=256–24xy=256–96= 160.

Solve the following formula for t.<br> A= J(1 + rt)
Lubov Fominskaja [6]

Explic

Pasos para resolver una ecuación linea

A=J(1+rt)

Usa la propiedad distributiva para multiplicar J por 1+rt.

A=J+Jrt

Intercambie los lados para que todos los términos de las variables estén en el lado izquierdo.

J+Jrt=A

Combina todos los términos que contienen J.

(1+rt)J=A

La ecuación está en formato estándar.

(rt+1)J=A

Divide los dos lados por 1+rt.

rt+1(rt+1)J=rt+1A

Al dividir por 1+rt, se deshace la multiplicación por 1+rt.

J=rt+1A

The sum of three numbers is 90. The third number is 10 less than the first. The second number is 3 times the third. What are the
Katyanochek1 [597]

Answer:

16

26

48

Step-by-step explanation:

x + y + z = 90

z = x - 10 => x = z + 10

y = 3z

=>

(z+10) + 3z + z = 90

5z + 10 = 90

5z = 80

z = 16

x = z + 10 = 16 + 10 = 26

y = 3z = 3×16 = 48
