Answer: 3 1/6 + 4 5/6 = 8 1/6.
Step-by-step explanation:
Let’s leave the whole numbers out for a second. You add 5/6 and 1/6 and that equals 1 or a whole. You add that to the whole numbers on the side of the fractions. So 3+4+1 =8. This is how the answer is 8 1/6.
Hope this helps :)
Do 560 * .38 which is 212.8 or B, it could be C if you are rounding but 212.8 is the exact answer
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:
the answer is 4
Step-by-step explanation:
Use the Chinese remainder theorem. Suppose we set
. Then clearly taken modulo 12, the second term vanishes, and incidentally
; taken modulo 13, the first term vanishes, but the second term leaves a remainder of 2. To counter this, we can multiply the second term by the inverse of 12 modulo 13, which is 12 since
.
So, we found that
, but the least positive solution is
, and in general we can have
for any integer
.
Now, since
, or
, we know that there are 32 possible integers
that satisfy the congruences.
