93600 because 65 beats in a minute x 60 minutes every hour = 3900 beats every hour.
3900 beats every hour x 24 hours = 93600

20 + 17y = -6 + 15y<br><br> Can you help me find y?

MariettaO [177]

20 + 17y = -6 + 15y

First, regroup your terms.
$20 + 17y = 15y - 6$
Second, take away '15y' from each side.
$20 + 17y - 15y = -6$
Third, subtract '17y - 15y' to get '2y'.
$20 + 2y = -6$
Fourth, take away '20' from both sides.
$2y = -6 - 20$
Fifth, simplify '-6 - 20' to get '-26'.
$2y = -26$
Sixth, divide both sides by '2'.
$y = -\frac{26}{2}$
Seventh, how many times goes 2 go into 26? 26 ÷ 2 = 13.
$y = -13$

Answer: y = -13

Answer:

Step-by-step explanation:

LET ORANGES=X

PEARS ARE 3 TIMES =3X

LET CHILDREN=Y

IF WE GIVE 5 ORANGES PER CHILD WE NEED 5Y ORANGES.SO THIS =X

X=5Y........................I

IF WE GIVE 8 PEARS PER CHILD WE NEED 8Y PERARS...THERE ARE STILL 21 PEARS LEFT OUT AFTER THIS THAT IS

8Y+21=3X....................II

SUBSTITUTING FOR X FROM EQN.I..

8Y+21=3*5Y

15Y-8Y=21

7Y=21

Y=3

X==5Y=5*3=15..

SO CHILDREN =3

ORANGES=15

PEARS=3*15=45
