18-3=15
Originally pay 25 = 75
450-75=375
375 + 75 = 450
C) 18 people were originally going on the trip and 15 are going now.
Idk about D
3+c - (4+c)
pretend that there is a -1 in front of the bracket
3+c-1(4+c)
multiply the bracket by -1
(-1)(4)=-4
(-1)(c)=-c
3+c-4-c
3-4+c-c ( combine like terms)
+c-c=0
3-4=-1
-1+0=-1
Answer:
-1
Answer with explanation:
The equation of any line with slope 'm' and passing through any point 
is given by
As we know that the general equation of a line with slope 'm' is 
Comparing with the given equation 
we can conclude slope of the given line is 
Now we know that the product of slopes of perpendicular lines is -1
Mathematically we can write for perpendicular lines
Thus the slope of the required line is obtained from the above relation since it is given that they are perpendicular
Hence using the given and the obtained values the equation of the required line is
Part b)
The angle of intersection between 2 lines with slopes 
is given by
Comparing the equations of given lines
with the standard equation we get
Thus the angle of intersection becomes
Answer:
I don't see the number line
Step-by-step explanation:
i would love to help you out, but I don't see the number line I'm supposed to be referencing.
The ratio of Red Apples to Green Apples is 5:2. The proportion of red apple is 5/7.
The store sold 45 red apples.
So the combined amount of red and green apples sold = No of red apples sold divided by the proportion of red apples = 45/ (5/7) = 63
The combined amount of red and green apples sold is 63 apples.
