Answer:
6 matches
Step-by-step explanation:
Let’s call the teams A B C D
A will play B C D = 3 matches
B will play only C and D as it already played A, making 2 matches
C will play D, making 1 match
D has already played all
Total number of matches is thus 3 + 2 + 1 = 6 matches
Answer:
1. Teresa's expression s not equivalent because she did not multiply -7 and -4 correctly.
2. Bernette's expression is not an equivalent because she should multiply before subtracting.
3. Lucy's expression is equivalent because she distributed correctly.
Step-by-step explanation:
By definition, equivalent expression have the same value but they look different.
You can find equivalent expressions of any expression by simplifying.
In this case you have the following expression:
Then, you know that:
1. Teresa's answer is:
This is not an equivalent expression , because she did not multiply -7 and -4 correctly.
Remember that:
2. Bernette's answer is:
This is not an equivalent expression, because she should multiply before subtracting (She should apply the procedure Teresa applied)
3. Lucy's answer is:
This is an equivalent expression , because she distributed correctly (She multiplied each term inside the parentheses by -7)
Therefore, you can find an equivalent expression for the given expression by applying the Distributive property. Then:
It would be 2 bc u couldn’t round 0 because it’s less then 5
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.
First split your model into 10 equal sections then you shade/color in 6 of them.
There it goes that is 6/10 bench mark!
