Answer:
x=6,2
Step-by-step explanation:
Answer:
= 4
Step-by-step explanation:
sqrt 15 = 3.872
to approximate to the nearest whole number (integer), you take the first decimal number which is 8, since 8 is greater than 5, you will add one(1) to the whole number which is 3 to make it 4.
I would go about solving this by elimination because the x variables are already the same so all you would have to do is change one equation to the opposite signs and add them, so it would look like:
7y + 5x = 19
+ -3y - 5x = -7
-------------------
4y=12
y=3
Answer: 3:1
Step-by-step explanation:
I start with putting it as 36:12 than reduce. Both sides are divisible by 12 so you end up with 3:1
