The easy thing to do is eliminate x by subtraction
x + 7y = 24
- x - 9y = -24
-------------------
16y = 48
now solve for y and then substitute the value into either original equation to find x
Answer: the diameter is 7cm And the radius is 3.5 cm
Step-by-step explanation:
What is his net weekly pay?
Answer:
y = -1/2x + (-1)
Step-by-step explanation:
You want to isolate the x. So you can subtract both sides by 3/4 and get:
x<8-3/4
To do 8-3/4, you multiply the 8 by 4 to get a common denominator of 4.
32/4-3/4 which is 29/4 or 7 1/4
So your final answer is x<7 1/4 or any number less than 7 1/4
Hope this helps!
