Well here's an easy way:
Subtract 40p from £6.00 and you get £5.60
then divide that by the 80p per pineapple.
Answer: 7 Pineapples.
plug a=2 and b=4 in the expression
5(2)+7(4)
simplify
10+28
solve
=38
Answer: velocity-time graph
Step-by-step explanation: The principle is that the slope of the line on a velocity-time graph reveals useful information about the acceleration of the object. If the acceleration is zero, then the slope is zero (i.e., a horizontal line). If the acceleration is positive, then the slope is positive (i.e., an upward sloping line).
Answer:
The number of nickels is 15
The number of Dimes is 3
Step-by-step explanation:
Let the number of dimes Christine has be d
The number of nickels with christine be n
Then the number of Nickels Christine has will be
n = 5d ----------------------------------(1)
Now The total value of both dimes and nickels is = $1.05
This can be represented as
5n +10d = 105 (in cents)
From eq(1)
5(5d) + 10d = 105
25d+10d = 105
35d = 105

d = 3----------------------------------(2)
Substituting (2) in (1), we get
n = 5(3)
n = 15
Answer:
y=x-5
Step-by-step explanation:
slope of line s=-1= m1
lines are perpendicular m1m2=-1 m2=1
equations of t=y-y1=m2(x-x1)
y-2=x+3
y=x+5
