No solution
Step-by-step explanation:
There are no values of Z that makes this equation true.
Answer:
x = -4y/7 + 51/7
Step-by-step explanation:
First, you add all the numbers without variables and are on the same side.
7x - 4 + 4y + 8 = 55
Then you do the opposite sign (for example the opposite of addition is subtraction) of the two numbers without variables on the left side to add them to the right side(what you do on one side of the equation you must do on the other.
4x - 4 + 4 + 4y + 8 - 8 = 55 + 4 - 8
4x + 4y = 51
Then you get the x by itself by doing the same thing you did with the last step by this time with 4y. Because this has a variable, you don't add it onto the 51, but add as a different number.
4x + 4y - 4y = 51 - 4y
4x = -4y + 51
Now to isolate the x, you divide 4x by 4.
4x/4 = -4y/7 + 51/7
x = -4y/7 + 51/7
Your answer is x = -4y/7 + 51/7

Answer:
The correct option is D) 5:18.
Step-by-step explanation:
Consider the provided information.
A husband and wife can complete a certain task in 1 and 2 hours respectively.
Then in 1 hr the work done by the husband and wife is:
Thus, the work done is:
Rae and Herman, can complete the same task in 4 and 6 hours, respectively.
Then in 1 hr the work done by Rae and Herman is:
Thus, the work done is:
Now calculate the ratio as shown.
Ratio=5:18
Hence, the required ratio is 5:18.
Thus the correct option is D) 5:18.
