Answer:
No, because 70% of a class of 30 students would be 21, not 24
Step-by-step explanation:
Answer:
a + b = 5.30
a + b = 7
No
Step-by-step explanation:
Expressing the information as system of linear equation :
Let apples = a, oranges = b
If $5.30 is charged for one apple and one orange, then we have ;
a + b = 5.30 - - - (1)
If $14 is charged for 2 apples and 2 oranges, then we have ;
2a + 2b = 14 - - - - (2)
a + b = 7
Since both equations gives varying combined cost for equal amount of the fruit, then a unique cost cannot be obtained for each fruit from the systems of equation using simultaneous equation process.
From (1)
a = 5.30 - b
Put a = 5.30 - b in (2)
2(5.30 - b) + 2b = 14
10.6 - 2b + 2b = 14
10.6 = 14 - - - - - (variables cancels out).
Answer:
Angle 7 and angle 15
Step-by-step explanation:
- <em>Alternate Interior Angles are a pair of angles on the inner side of each of those two lines but on opposite sides of the transversal.</em>
Alternate interior angles with angle 9 are:
<u>Transversal s, parallel lines are t and u,</u>
- Angle 9 is in pair with angle 7
<u>Transversal u, parallel lines are s and r,</u>
- Angle 9 is in pair with angle 15
