Length:3x
width:x
3x•x=64
3x^2=64
x^2=21 1/3
x= about 4.6188
length:3(4.6188)=13.86 meters
width=4.62 meters
If Yellow is x
Then purple is 3x-8
The total is 64, so x+3x-8=64
x=18
3*18-8=46
C. In each of the other instances, you will get a w term. This one will cause the w the w term to cancel out as it does in the original.
Answer: Mr Smith bought 7 pepperoni pizza
Step-by-step explanation:
Step 1
cost of cheese pizza =$11
pepperoni pizza cost =$12.50
let number cheese pizza be represented as c
and number of pepperoni pizza be represented as p
such that the total number of pizza bought which equals 13 can be represented as
c+ p= 13
and total cost of both pizza can be expressed as
11c+ 12.50p =153.50
Step 2 Solving
c+ p= 13
11c+ 12.50p =153.50
By elimination method, Multiply equation 1 by 11 and subtract the new equation from equation 2
11c+ 12.50p =153.50
11c+ 11p=143.
1.5p =10.5
p= 10.5/ 1.5 =7
c+ p= 13
c= 13-p =13-7=6
Therefore Mr Smith bought 6 cheese pizza and 7 pepperoni pizza
I don’t know- the first thing I would think is that x=15*y because 30=15*2
So that’s my thinking, which means that if x=5, then y=5/15 or 1/3 or as a decimal .33
However I’m not sure if that’s right- I hope it helps!
