For Q's a to d
a) 2 x 3/4 = 6/4 = 1 2/4 = 1 1/2
<span>b</span>, c and d follow the same pattern
For Q's e to h we use <span>fraction</span> multiplication:
f) 4/5 x 2/3 = 8/15
For Q's <span>i</span> to l we have to change the mixed numbers to top heavy fractions and then multiply:
j) 1 1/2 is equal 3/2 and 1 1/3 is equal to 4/3
Therefore 1 1/2 x 1 1/3 = 3/2 x 4/3 = 12/6 = 2
I hope that this gives you enough information to go on
Answer:
80
Step-by-step explanation:
We let x be Ann's savings.
Betty saves 3 times as much as Ann.
This implies that Betty's savings in terms of x
Charles save 390 less than Ann.
This implies Charles savings
Betty saves 1330 more than Charles.
This implies that when we deduct Charles savings from Betty's we have to get 1330.
Mathematical equation for the problem:
Expand :
Subtract 390 from both sides.
Divide through by 2
Hence Charles saving is
Answer:
16x
Step-by-step explanation:
17 $ because I added and then times everything
Answer:
A and B
Step-by-step explanation:
The minimum occurs at the turning point ( vertex )
The coordinates of the vertex are (1, - 2 ) → A
The x- intercepts are the points where the graph crosses the x- axis
This occurs at (3, 0 ) and (- 1, 0 ) → B
The axis of symmetry is a vertical line passing through the vertex
Equation of axis of symmetry is x = 1 , not y = - 2
(1, - 2 ) is a minimum not a maximum , see above
