The cost of one pizza is $8.5
Step-by-step explanation:
Let,
Cost of one pizza = x
Cost of one bread stick = y
According to given statement;
3x+2y=29.50 Eqn 1
2x+3y=23 Eqn 2
Multiplying Eqn 1 by 2
Multiplying Eqn 2 by 3
Subtracting Eqn 3 from Eqn 4
Dividing both sides by 5
Putting y=2 in Eqn 1
Dividing both sides by 3
The cost of one pizza is $8.5

I hope this helps you
x^2-6x+9= -1
(x-3)^2= -1
(x-3)^2=i^2
x-3=i
x=3+i
x=3-i
or we can find disctirminant
x^2-6x+10=0
a=1
b= -6
c=10
disctirminant=b^2-4ac
disctirminant=(-6)^2-4.1.10
disctirminant=36-40
disctirminant= -4
i^2= -1
x1,2= -b (+,-) square root of disctirminant /2a
x1= -(-6)+square root of -4/2.1
x1=6+2i/2=3+i
x2= -(-6)-square root of -4/2.1
x2=6-2i/2=3-i
Answer:
2x = 58 Step-by-step explanation:
x= 29
29+ y = 54
y = 54 - 29
y = 25
Check
29+25=54 √
29 - 25 = 4 √
Answer:
12,500-11,625=875
875/12,500=7/100
7/100*100=7
The percentage reduction is 7%
