Answer:
x = 3
y = 4
Step-by-step explanation:
-4x+2y=-4 -----(eq1)
4x-5y=-8 ------(eq 2)
by elimination,
(eq1) + (eq 2),
(-4x+2y) + (4x-5y) = -4 + (-8)
-4x+2y + 4x-5y = -4 -8
2y-5y = -12
-3y = -12 (divide both sides by -3)
y = -12 / (-3) = 12/3 = 4 (sub back into (eq 1) )
-4x+2y=-4 -----(eq1), when y = 4,
-4x+2(4)=-4
-4x+8 = -4 (subtract 8 from both sides)
-4x= -4 - 8
-4x= -12 (divide both sides by -4)
x = -12 / (-4) = 3
Answer:
The heaviest baby have to gain to reach a healthy level by 42 ounces.
Step-by-step explanation:
It is said that the 500-gram babies are going to have to make four times their weight [to reach a healthy level].
So, the healthy level of weight is (500 × 4) = 2000 gm i.e. 2 kg.
Now, 1 kg is equivalent to 35.274 ounces.
So, 2 kg will be equivalent to (35.274 × 2) = 70.548 ounces.
So, the heaviest baby with weight 28.6 ounces have to gain weight to reach a healthy level by (70.548 - 28.6) = 41.948 ounces ≈ 42 ounces. (Answer)
