Answer:
D) x=70 y=80 is your answer
70>60 (guys)
80<90 (girls)
Step-by-step explanation:
Answer:
B & D
Step-by-step explanation:
The quadratic formula can be used to solve for x for any quadratic. Recall a quadratic is any function whose highest exponent known as degree is 2. Looking at the answer selections, A has one term with exponent 3. This isn't possible in the formula. Looking at answer C, the term with exponent 2 has the same coefficient on each side of the equal sign. When it is rearranged these will cancel out no exponent of 2 will be in the equation anymore. Only B & D work after being rearranged and simplified
3s represents the 3 shirts × s which is the unknown price.
2p represents the 2 pairs of pants × p which is the unknown price.
The slope is plus two. This graph is going to go from quadrant 3 to quadrant 1. That means it is neither horizontal or vertical. I've enclosed the graph to show you what it does. I think you want tilted right upwards. I can guarantee tilted.
Tilted right upwards <<<<<< answer
Since its a linear pair,
(2x+4)° + (x+23)° = 180° (Since a linear pair = 180°)
2x+x+4+23 = 180°
3x+27 = 180°
3x = 180° - 27
3x = 153°
x =153/3
x = 51
Therefore, (2x+4)° = 2*51+4
= 106°
&
(x+23) = 51+23
= 74°
Hope you understood!
