Step-by-step explanation:
x and x+2
x+3(x+2)=98
x+3x+6=98
4x=92

X^2 +3x-4=0
(X+4)(x-1)=0 so x = -4 and x=1 are solutions
Answer:
1 Adult ticket=$21.50 ; 1 Children ticket=$15.50
Step-by-step explanation:
3A+4C=126.50
2A+5C=120.50
We find the price of adult tickets 1st.
15A+20C=632.5
8A+20C=482
7A=632.5-482=150.5
1A=21.50
Now we find Children ticket
6A+8C=253
6A+15C=361.50
7C=108.50
1C=15.50
Answer:
-17x - 27
Step-by-step explanation:
Distributive property is the multiplication of the number outside the parenthesis and the ones inside.
-5(x + 4) + -3x + -9x + -7
-5x - 20 + -3x + -9x + -7
Combine like terms:
-5x - 20 + -3x + -9x + -7
-5x +-3x
-8x + -9x
-17x
-17x - 20 + -7
-20 + -7
-27
The answer is -17x - 27
Hope this helped.
