The length of a rectangle is twice the width. The perimeter is 25. The system to help find the length and width is:
L=2W

2L+2W=25

Aaron tried using a graph to find the measurements but was unsure of the exact values. Use substitution to solve the system exactly. Round to the nearest hundreth.

Answers

9514 1404 393

Answer:

  (L, W) ≈ (8.33, 4.17)

Step-by-step explanation:

Substituting for L, we have ...

  2(2W) +2W = 25

  6W = 25

  W = 25/6 ≈ 4.17

  L = 25/3 ≈ 8.33

The rounded "exact" solution is ...

  (L, W) = (8.33, 4.17)

Let the width be x
Since the question mentions the length is twice the width,
let the length be 2x
The total perimeter given is 25cm and as we know, perimeter for a rectangle :
=> P = 2(Length + width)
So,

25cm = 2(2x + x)
25 = 4x + 2x
25 = 6x
25/6 = x
4.166666667 = x

I really need help on this idk how to do this and its due tonight.

Answers

X = (-14)

hope that this helps let me know if you need explanation
X=-14 and I think they’re equal so you just set them equal and get the x to one side and then solve for x

Solve For X: 8.47 = 5.5 + X

Answers

Answer:

x=2.97

Step-by-step explanation:

Answer:

x=2.97

Step-by-step explanation:

8.47=5.5+x

Step 1: Simplify both sides of the equation.

8.47=x+5.5

Step 2: Flip the equation.

x+5.5=8.47

Step 3: Subtract 5.5 from both sides.

x+5.5−5.5=8.47−5.5

x=2.97

Answer:

Its c. c = 50.

Step-by-step explanation:

First, we need to figure out what the equation equals.

7 + 7/7 + 7*7 - 7 = x

PEMDAS

Parentheses, exponents, division/fraction, addition, subtraction.

7/7 = 1. So equation changed into 7 + 1 + 7*7 - 7 = x.

7*7 = 49. So equation changed again into 7 + 1 + 49 - 7.

Lets calculate it. 7 + 1 = 8 + 49 = 57 - 7 = 50. x = 50.

c is the only one who has a calculation of 50.

The highest recorded temperature in Yuma, Arizona, was about 51∘C, and the lowest recorded temperature was about −11∘C. What equation can be used to find the difference between the highest and lowest temperatures?

Answers

51.C - 11.C = 40.C

Even though 11 was a negative number we are only looking for the difference between the two so negatives don’t play much part.

A number cube, with number 1 through 6, is rolled and a coin is tossed. What is the probability of rolling an odd number on the cube and tossing a tails on the coin? Write your answer as a fraction in simplest form in the box provided.

Answers

Answer:

Step-by-step explanation:

Simple joint probabilites of two independent event. Probability of a head is 1/2. An odd roll of a die is also 1/2. 1/2 x 1/2 = 1/4 or 0.25.

So an odd roll on the cube is 1/2 and it’s 1/2 of getting tails so the probably is 0.25
