y=2x-3 an x+y=3
subsitution
since y=2x-3, put (2x-3) wherever you see y
put taht in the other equation
x+y=3
x+(2x-3)=3
x+2x-3=3
3x-3=3
add 3 to both sides
3x=6
divide by 3
x=2
subsitute back
y=2x-3
y=2(3)-3
y=6-3
y=3
so the solution set in (x,y) form is (2,3)
Answer:
The probability of a customer getting a leash for their dog along with a treat for their doctors is 1/2.09
Step-by-step explanation:
This is example of conditional probability.
Let A represents the % of customer getting a leash for their dogs
Let B represents the % customer getting a leash + treat for their dogs
As we know-
P(A|B)=P(A and B)/P(B)
So the probability is
P(A|B)= 0.32/0.67 = 1/2.09
There is the closure property of multiplication, addition, subtraction, etc

Answer:
36 inches
Step-by-step explanation:
Given data
Area of triangle =2 1/4 square inches
Area =9/4 square inches
Height of triangle =1/8 inches
We know that the expression for the area of triangle is
Area = 1/2Base *Height
9/4=1/2*Base *1/8
9/4=Base/16
Cross multiply
16*9=Base*4
144=Base*4
Base =144/4
Base=36 inches
