Step-by-step explanation:

The length of the longest piece will be 15 ft.

We have a 48 ft rope is cut into 5 pieces according to the ratio →

2 : 2 : 3 : 4 : 5.

We have to determine the length in feet of the longest piece.

Now -

2x + 5x = y

x = [tex]$\frac{y}{7}[/tex]

Smallest piece is of length → 2x → [tex]$\frac{2y}{7}[/tex]

According to the question, we have -

Length of rope = 48 ft

Ratio in which they are cut = 2 : 2 : 3 : 4 : 5.

Therefore -

2x + 2x + 3x + 4x + 5x = 48

16x = 48

x = 3

Length of the longest piece = 5x =  5 x 3 = 15ft

Hence, the length of the longest piece will be 15 ft.

Product = 7

Sum = 8

Factors = 1 , 7

x² + 8x + 7 = x² + 7x + x + 7

Step-by-step explanation:

Let's solve for x to see what range the answer has to be in:

-2x - 3 ≤ -1

-2x ≤ 2

x ≥ -1

So the value of x must be larger than or equal to -1. So the answers would be 1 and 0

Answer:

3 points = 2

2 points = 6

1 point = 8

Step-by-step explanation:

Given that:

Total point scored = 26

Let number of 3 point basket = x

Number of 2 point basket = x + 4

Number of free throws = x + x + 4 = 2x + 4

Hence,

Total 3 points = 3x

Total 2 points 2(x + 4)

Total free throw points = 2x + 4

3x + 2(x + 4) + 2x + 4 = 26

3x + 2x + 8 + 2x + 4 = 26

7x + 12 = 26

7x = 26 - 12

7x = 14

x = 2

Number of 3 points = x = 2

2 points = (x+4) = 2+4 = 6

1 point = (2x+ 4) = 2(2) + 4 = 8

The number of free-throws, 2-point shots, and 3-point sho ts he made are;

free-throws = 8

2 points = 6

3 points = 2

Let the number of 3 points basket be x

He scored four more 2-point baskets than he did 3-point baskets. Thus;

y = x + 4

number of free-throws equaled the sum of the number of 2-point and 3-point sho ts made. Thus;

z = x + x + 4

z = 2x + 4

Thus;

Total 3 points = 3x

Total 2 points = 2(x + 4)

Total fr ee points = 2x + 4

Since he scored a total of 26 points, then;

Step-by-step explanation:

let amt of money Raju has be r and Ann be a.

a + r = 1560

a = 1560 - r --(1)

r - 50 = 5(a + 50)

r = 5a + 300 --(2)

sub (1) into (2):

r = 5(1560 - r) + 300

r = 8100 - 5r

6r = 8100

r = 1350

therefore he has $1350 at first.

The amount of money Ann has at first is $1350.

An expression is a sentence with a minimum of two numbers or variables and at least one math operation such as addition, subtraction, multiplication, or division.

We have,

Let the amount of money Raju = R

Let the amount of money Ann = A

Now,

Raju and Ann saved a total of $1560.

This statement can be written as:

R + A = 1560 ____(1)

After Raju gave Ann $50, Raju had 5 times as much money as Ann.

This statement can be written as:

R - 50 = 5 ( A + 50 )

R - 50 = 5A + 250

R - 5A = 250 + 50

R - 5A = 300 _____(2)

From (1)

R = 1560 - A _____(3)

Putting (3) in (2),

1560 - A - 5A = 300

1560 - 6A = 300

1560 - 300 = 6A

1360 = 6A

A = 1260 / 6
A = 210

Putting A = 210 in (3) we get,

R = 1560 - A

R = 1560 - 210

R = 1350

Thus the amount of money Ann has at first is $1350.

Answer:

The hotel manager under-estimated. Without estimation, the exact price would be $17,556.

Step-by-step explanation:

He should've over-estimated the money to $210, and the mattresses to 90.  So 210 × 90 is $18,900. So even if he did underestimate or overestimate, he still would not have been able to afford the mattresses.

Answer:

hotel has a budget of $16,000 to buy 84 new mattresses. Each mattress costs $209. The hotel manager says, “Since 80 × $200 = $16,000, I can stay within the budget.”
