Answer:
d. 5(x + 6) = 47.50
Step-by-step explanation:
First, determine the number of girls; (4 friends + Jacquenline) making a total of 5 girls.
If a ticket costs $6, then the the 5 girls' tickets would cost= 5*6
Also, if a funnel cake costs $x , then 5 girls' cakes would cost= 5* x
Total cost of funnel cake and entry tickets = $47.50
Now make the above three into an equation;
(5*x) + (5*6) = 47.50
5 is the common number on the left side so it becomes;
5( x +6) =47.50
Answer:
9x^2 -2x+8
Step-by-step explanation:
( 9x^2 -5x) - ( -3x -8)
Distribute the minus sign
( 9x^2 -5x) +3x +8
Combine like terms
9x^2 -2x+8
The x^2 should be positive and you have it as negative
Answer:
x = 90°
Step-by-step explanation:
a triangles angles are equal to 180°
so if we have one that is 70° and one that is 20° what s x?
70° + 20° = 90°
180° - 90° = 90°
x = 90°
