Z = 1
It all makes sense, you can try it yourslef
Answer:(1, -3).
Step-by-step explanation:
If y=2x-5 is equation (1) and 4x-y=7 is equation (2), then substitute equation (1) in equation (2):
4x - (2x - 5) = 7
4x - 2x + 5 = 7
2x = 7-5
2x = 2
x = 1
Now substitute the value of x in equation (1) to find the value of y:
y = 2 (1) - 5
y = 2 - 5
y = -3
Answer:
Mr. Martin's statement is correct.
Step-by-step explanation:
First we select a value of q that is less than 6:
q = 3
Then we <u>write the equation:</u>
And <u>solve for x</u>:
The solution is positive because x > 0.
--
Then we select a value of q that is not less than 6:
q = 9
Then we <u>write the equation:</u>
And <u>solve for x</u>:
The solution is negative because x > 0.
If 2/3 ton of gravel covers 3/4 of a driveway, you need to divide 2/3 divided by 3 to find how much is needed for 1/4 of the driveway.
Steps:
1. 2/3 divided by 3 = 2/3 * 1/3. So 2/9.
2. Add 2/3 plus 2/9= 8/9 ton of gravel to cover the whole driveway.
Answer: 8/9
Hope this helped, and good luck with any future problems
