3/4 multiplied by 3/10 gives a smaller product that 3/10 and 7/5 multiplied by 3/10 gives a larger product than 3/10
Answer:
Jill bought 16 books and Sam bought 9 books
Step-by-step explanation:
Let the number of books that Jill bought be j.
Let the number of books that Sam bought be s.
Jill bought 7 more books than Sam:
j = 7 + s
They bought 25 books altogether:
j + s = 25
Put j = 7 + s into the second equation:
7 + s + s = 25
7 + 2s = 25
2s = 25 - 7 = 18
s = 18/2 = 9 books
Therefore:
j = 7 + s = 7 + 9
s = 16 books
Jill bought 16 books and Sam bought 9 books.
1. the number five plus x
2. the number five minus x
3. five times x
4. five divided by x
5. three-forths of x plus two
6. two minus three-forths of x
7. three times x plus ten
8. ten times x plus three
x = 18
The value "18" from the data set makes the equation true.
x + ( x + 1 ) + ( x + 2 ) = 57
18 + ( 18 + 1 ) + ( 18 + 2 ) = 57
18 + 19 + 20 = 57
57 = 57
The answer should be 15
15x2=30
5x1=5
