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.

What is the value of s in the equation

galben [10]

The answer is B. 16 because you multiply 4 with 2s and -1 so the new equation will be 8s-4=7s+12 and you have to subtract the variable 7s to 8s the equation will be 1s-4=12 and add 4 to 12 and it gives you 16 and just divide 16 and one and you answer should be 16. :)
