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
THANKYOU AND PLEASE AMRK IT BRAINLIEST
Hi there!
First, we'll subtract 48 from 231 because we need to figure out how many cookies in total were given out to the fourth grade classes. This leaves us with 183 cookies for all classes. Then, we need to divide 183 by 3 to figure out how many cookies each fourth grade class got. Doing this leaves us with 61 cookies per class.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Answer:
Area of rectangular land = 6x² - 28x + 30
Step-by-step explanation:
Given:
Length of rectangular land = 2x - 6
Width of rectangular land = 3x - 5
Find:
Area of rectangular land
Computation:
Area of rectangle = Length × Width
Area of rectangular land = [Length of rectangular land][Width of rectangular land]
Area of rectangular land = [2x - 6][3x - 5]
Area of rectangular land = (2x)(3x) - (2x)(5) - (6)(3x) + (6)(5)
Area of rectangular land = 6x² - 10x - 18x + 30
Area of rectangular land = 6x² - 28x + 30
The roots to this equation are: (2,0) and (24,0)
