Sara wants to buy a tennis racket for $120. She has $40 and is saving $10 every week. The owner of the store decreases the rackets price by $5 each week he doesnt sell it. How many weeks until Sara has enough money to buy the racket?
Answers
Answer:
After the sixth week, she would have more than enough money to buy the racket.
Step-by-step explanation:
First Week
Sarah = 40 + 10 = 50
Owner = 120 - 5 = 115
Second Week
Sarah = 50 + 10 = 60
Owner = 115 - 5 = 110
Third Week
Sarah = 60 + 10 = 70
Owner = 110 - 5 = 105
Fourth Week
Sarah = 70 + 10 = 80
Owner = 105- 5 = 100
Fifth Week
Sarah = 80 + 10 = 90
Owner = 100 - 5 = 95
Sixth Week
Sarah = 90 + 10 = 100
Owner = 95 - 5 = 90
After the sixth week, she would have more than enough money to buy the racket.
How many weeks until Sara has enough money to buy the racket?

3x + 5x -1 anwser equation
Answers
Answer:
8x - 1
Step-by-step explanation:
You cannot actually solve this equation because you have no value that it is equal to, but you can simplify it down by combining like terms:
3x + 5x - 18x - 1Hope this helps!!
8x-1
You can't subtract a normal number by a number paired with a variable. So the only thing that you would have to do is add 3x and 5x together and keep the -1 there.

Calculate 48 x 3/8 choose the numbers to complete the equation
Answers
Answer:
1. Choose: 3
2. Choose: 144
3. Choose: 18
Step-by-step explanation:
The first thing you do is multiply 48 * 3/8= 18. Then multiply 48 * 1/8= 6. Then divide both answers to get 3, so 48 * 1/8 * 3.
Then to find the second Choose option, you know that 48 * 1/8 * 3= 18; so 18 * 8= 144(to check your answer, divide 144/8 = 18).
Finally, to find the third Choose option, you divide the fraction 144/8 = 18.

For the expression 6 − y + 3, determine the coefficient for the variable term.
A −1
B 0
C 3
D 6
Answers
Answer:
A -1
Step-by-step explanation:
The coefficient is the number in front of a variable. since there isn't a number we can conclude that the y is only there once. There is 1 (one) y. Since it is subtracting in front of the coefficient, we can determine it is taking one away, or -1. So 6-y+3 is 6-1y+3.

Which of the following cannot be the lengths of the sides of a triangle?
O 6, 8, 12
O 4,4,6
O 6, 6, 12
O 10, 8, 6
Answers
Given:
The sides of a triangles in the options.
To find:
Which of the following cannot be the lengths of the sides of a triangle?
Solution:
In a triangle, the sum of two smaller sides must be greater than the longest side, otherwise it cannot be the lengths of the sides of a triangle.
For option A,
[tex]6+8=14>12[/tex]
For option B,
[tex]4+4=8>12[/tex]
For option C,
[tex]6+6=12[/tex]
Here the sum of two smaller sides is not greater than the longest side. So, the sides 6, 6, 12 cannot be the lengths of the sides of a triangle.
For option D,
[tex]6+8=14>10[/tex]
Therefore, the correct option is C.
