The product of three is the same as [ * 3 ]
The sum of a number and five is the same as [ n + 5 ]
[ 3 ] is being multiplied to the sum of [ n + 5 ], so, we can write this using the distributive property [ a(b + c) ]
Put the expression together:
3(n + 5)
Best of Luck!
How generous
x+3=8
minus 3 both sides
x+3-3=8-3
x+0=5
x=5
The answer for the question shown above is: <span>The square footage of a house that is 1200 square feet is the "</span>Area".
The explanation is shown above:
1- By definition, the area is the measure of a two-dimensional surface.Its units can be written in m^2, ft^2, in^2...However, in the International System of Units is m^2.
2. This is very useful when you want to know the surface of a house. If it is a rectangular house, you can calculate the area as below:
A=LxW
Where L is the length and W is the width
Answer:
Adults =1500 and student= 2500
Step-by-step explanation:
Step one:
GIven data
let Adults be x and student be y in numbers
so
5x+3y=15000------------1
x+y=4000---------------------2
from 1
x=4000-y, put this in 2, we have
5(4000-y)+3y=15000
20000-5y+3y=15000
-2y=15000-20000
-2y= -5000
2y=5000
divide both sides by 2
y= 2500
put y= 2500 in 2
x+2500= 4000
x= 4000-2500
x=1500
