Answer:
D
Step-by-step explanation:
DDDDdDDDD
let the two numbers be x and y
From the first sentence,
xy=24
x+y=10
Then make y in equation 2 the subject of the formular and substitute in equation 1
x+y=10
y=10-x
substituting in equation 2
x(10-x)=24
open the bracket
10x-x^2=24
=-x^2+10x=24
Transfer the constant to the left hand side
=-x^2+10x-24=0
Then factorise completely

Answer:
B
Step-by-step explanation:
Both games have the same probability so it does not matter which one you choose. Game A gives a ticket 1/3 of the time and costs two tokens to play so you need 6 tokens to win a ticket. Game B gives a ticket 1/2 and costs three tickets to play so you also need 6 tokens to win a ticket.
Answer:
width = 12 Inches
length = 27 Inches
Step-by-step explanation:
Perimeter of Rectangle Formula is 2(l+w), Therefore,
2(l+w)=78 inches (Equation 1)
l= 2x+3 (Equation 2)
Let width be x
Putting width as x and l as 2x+3 in equation 1
2(2x+3+x)=78
2(3x+3)=78
6x+6=78
6x=72
x=12
Putting width=>x =12 inches in equation 2 to find the length
l=2(12)+3
l=27 inches
