3x + 4y = -11
4y = -3x - 11
y = -.75 - 2.75
and
7x - 5y = 3
-5y = -7x + 3
y = 1.4x - .6

balandron [24]

Answer: Distance between dolphin and helicopter = 93.5 feet

Explanation:

Distance at which dolphin swimming below the ocean= (-) 18 feet

(it is represented as the negative number as it denotes the distance below the ocean)

Distance at which helicopter is above the ocean = (+) 75.5 feet

(it is represented as the positive number as it denotes the distance above the ocean)

Distance between dolphin and helicopter = 75.5 - (-18) feet

= 75.5 + 18 feet

= 93.5 feet

Jane and Mo have 528 parcels to

Temka [501]

Answer:

Jane gave 132 parcels to Mo.

Step-by-step explanation:

Given total number of parcels both Jane and Mo have = 528.

Let the number of parcels having Jane and Mo be x and y respectively.

$Therefore\ x\ +\ y\ =\ 528\ equation\ 1\\x\ =\ 3y\ equation\ 2$

Now let the number of parcels Jane gives to Mo be z.

$So\ according\ to\ question\ x-z = y+z\\3y-z=y+z(from\ equation\ 2)\\2y=2z\\y=z$

$x+y=528\\3y+y=528\\4y=528\\y=132\\y=z=132$

So the number of parcels Jane give to Mo is 132.
