The arithmetic sequence is +3 for every number you move to the right.
29. 5/2× 2/5×=5/2×7 multiply the equation by the reciprocal of the coefficient
x= 5/2×7/1 <span> reduce the numbers with 5,2. convert the expression into a fraction
</span><span>
x= 5</span>×7/2×1
<span>
x= 35/2
32. a= 19/6
2 3/4a = 19 1/4 divide both sides of the equation by 1/4
2</span>×3a=19 calculate the product <span>
</span>
6a=19 divide both sides by 6
a=19/6
Its 60 because l*w*h so 4*5*3=60
Answer:
the cost of each notebook is $4.8
Step-by-step explanation:
Cost of each notebook= ?
Cost of a poster = $6
Total amount she spent = $20.40
If we subtract the cost of poster from total amount we get the cost of 3 notebooks.
$20.40-$6
=$ 14.4
It means the cost of 3 notebooks = $14.4
To find the cost of each notebook divide the cost of 3 notebooks by the number of books.
=14.4/3
=$4.8
Thus the cost of each notebook is $4.8....
