Answer:
The new granite countertop will cost $824.
Step-by-step explanation:
Step 1: The problem is to determine how many yards per square that the countertop is made up of.
This is the equivalent of finding the square area of the countertop.
The formula for the square area of a rectangle is given as L x W.
Where L = Lenght which is equal to 3 yards
W = 1 yard
Step 2:
Cost of per square yard required therefore is
3 x 1 = 3 square Yards.
The granite required for the countertop project therefore will cost:
$206 x 3 = $824.00
Cheers!
Answer:
x - y = 3
2x - 3y = 4
Igualación
Despejamos una de las incógnitas en cada ecuación e igualamos. (En este caso la x)
3y + 4
x = y + 3 x = ---------------
2
3y + 4
y + 3 = ---------------
2
2 (y + 3 ) = 3y + 4
2y + 6 = 3y + 4
se pasan las incógnitas a un lado y lo que cambia de lado se cambia de signo
3y - 2y = 6 - 4 ⇒ y = 2
sustituimos el valor de y en cualquiera de las dos para obtener el valor de x
x - 2 = 3 ⇒ x = 5
Solución
x = 5
y =2
Answer:
1/2
Step-by-step explanation:
16,8,4,2
it is decreasing by 2 each time
or we can call it multiplying by 1/2
16* 1/2 = 8
8* 1/2 = 4
4* 1/2 =2
