Which ordered pairs in the form (x, y)(x, y) are solutions to the equation 3x−4y=213x−4y=21 ?

Natalija [7]

None of these couples are solutions, (11, 3)(11, 3); (−1, −6)(−1, −6); (−3, 3)(−3, 3); <span>(7, 0). Perhaps the choice of answer are insufficient. we can add (1, 48) the couple (7, 0) and (7, 0)(1, 48) is a true answer, why? because it verifies the equation.</span>

Find three consecutive integers whose sum in 36

ratelena [41]

ANSWER: 11, 12, 13

3 consecutive integers:
$x \\ x + 1 \\ x + 2$
"Sum" means Add

$x + x + 1 + x + 2 = 36$
Combine like-terms
$3x + 3 = 36$
Solve for X
$3x + 3 = 36 \\$
Subtract 3 from both sides
$3x = 33$
Divide by 3 on both sides
$x = 11$
11 + 1 = 12
11 + 2 = 13
