Taylor bought a necklace for each of her three sisters. She paid $7.50 for each necklace. Supposed she had $9 left. How much money did she have initially to spend on each sister?
Answer:
7.50 x 3= 22.50
22.50+9= 31.50
Step-by-step explanation:
If each necklace was $7.50 and she got one for each of her 3 sisters then we need to multiply $7.50 by 3. Finally, she has $9 left over. So if we add the total she spent on the necklaces and the 9 she has left over then we will get the total she started with.

2(x+5)=3x+1
Answer:
x = 9
Step-by-step explanation:
2(x + 5) = 3x + 1
open the parenthesis
2x + 10 = 3x + 1
subtract 2x from both sides of the equation
2x - 2x + 10 = 3x - 2x + 1
10 = x + 1
subtract 1 from both sides of the equation
9 = x
Answer:
Step-by-step explanation:
Substitute
2x+10=3x+1
Subtract 3x to other side
-x+10=1
Subtract 10
-x=-9
divide -1 both sides
x= 9

What is the largest integer value of n for which 3√ n is less than √ 200? Be sure to explain how you got your answer.
Step-by-step explanation:
[tex]3 \sqrt{n} < \sqrt{200} \\ \sqrt{n} < \sqrt{200} \div 3 \\ \sqrt{n} < \sqrt{200 } \times \sqrt{1 \div 9} \\ \sqrt{n} < \sqrt{200 \times (1 \div 9)} \\ \sqrt{n } < \sqrt{22} \\ n < 22 \\ n = 21[/tex]
200/9=22.22222
so i took the nearest number 22 just to make it easy. I think there is no problem.

What is the length of the third side of the window frame below?
A. 10 inches
B. 12 units
C. 16 units
D. 20 units
Answer:
20 units
Step-by-step explanation:
a^(2)+b^(2)=c^(2)
48^(2)+b^(2)=52^(2)
2304+b^(2)=2704
2304-2304+b^(2)=2704-2304
b^(2)=400
\sqrt(b^(2))=\sqrt(400)
b=20
therefore,20 is the length of the unknown side
