<span>The question is asking us to "find the missing number ___:7 = 12:21 First, let's see how similar are 7 and 21 - 21 is 7 multiplied by 3. So the gap will be filled in by something that multiplied by 3 will give us 12. So we have : x*3=12, and also: x=12/4=4, so the answer is C.4</span>

To be blunt, it looks like you just copy/pasted a wall of text from whatever you're working on. Ask an actual question, and format the wall of text so that we don't have to decipher it ourselves. Don't expect people to help solve a problem like that if it looks like you gave no thought in posting it

myrzilka [38]

Answer:

19 days

Step-by-step explanation:

1 - Make an equation with the variables provided.

150 + 200 + 12.50x = 587.50

2 - Simplify both sides.

350 + 12.50x = 587.50

3 - Subtract 350 from both sides.

12.50x = 237.50

4 - Divide by 12.50 to find your x variable.

x = 19 days

Find the length of the hypotenuse
denpristay [2]

Answer: The answer is “10cm”

Step-by-step explanation: To get to this answer we first need to know the formula for find the hypotenuse which is a^2 + b^2 = c^2. A and B are the two sides in this case a and b are 8 cm and 6 cm. Then you plug in the values into the equation, it looks like this 8^2 + 6^ = c^2 once you solve you get 64 + 36 = c. When you add 64 and 36 you get 100 but their is one more step. You must find the square root of 100 which is 10. So your answer for the hypotenuse is “10cm”

Have a nice day!
