Answer:
-8 or -1
Step-by-step explanation:
x*2+9x+8=0
(x+8)(x+1)=0
x+8=0 or x+1=0
x= -8 or x= -1
The commmutative property says that ab=ba, you can change the order
the identity property is 1 times a=a
the distributive is a(b+c)=ab+ac
associative is moving parenthssees with multiplicaon and addiotn or a(bc)=(ab)c
the answer is commutative property since you change the order
Answer:
The admission cost of each adult is $11.5 and that of each children is $6.5.
Step-by-step explanation:
Let the admission cost for children to the museum is $x.
So, the admission cost for adults to the museum is $(x + 5) {As per given condition}
Now, given that admission to the museum for Barbara and Jeff Johnson and their five children cost fifty-five dollars and fifty cents.
Hence, 2(x + 5) + 5x = 55.5
⇒ 7x = 45.5
⇒ x = $6.5
So, $(x + 5) = $11.5
Therefore, the admission cost of each adult is $11.5 and that of each children is $6.5. (Answer)
