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.

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

Answer:

45 words per minute

Step-by-step explanation:

60 / 1 [tex]\frac{1}{3}[/tex]

45

The average typing speed of Joseph in words per minute is 45 words per minute​.

The average speed is the total distance traveled by the object in a particular time interval. The average speed is a scalar quantity.

Now it is given that,

Number of words = typed 60 words

Time taken = 1 and 1/3 minutes

⇒ Time taken = 4/3 minutes

Thus, Average typing speed = Number of words / Time taken

⇒ Average typing speed = 60 / (4/3) words per minute​

⇒ Average typing speed = 45 words per minute​

Thus, the average typing speed of Joseph in words per minute is 45 words per minute​.

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.

B. 25.92 square centimeters.

Step-by-step explanation:

Brady's rectangle has an area of 35.52 cm^2

Staci's rectangle with area of 61.44 cm^2

So, Staci's rectangle is 61.44 -35.52 cm^2 more than Brady's.

Let's simplify it,

It gives 25.92 cm^2

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
