The answer is 3.15 rounded to the hundredths.
Answer:
Step-by-step explanation:
Multiply the first equation by 4,and multiply the second equation by 1.
4(x−3y=−6)
1(−4x+9y=9)
Becomes:
4x−12y=−24
−4x+9y=9
Add these equations to eliminate x:
−3y=−15
Then solve−3y=−15for y:
−3y=−15 (Divide both sides by -3)
y=5
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
x−3y=−6
Substitute5foryinx−3y=−6:
x−(3)(5)=−6
x−15=−6(Simplify both sides of the equation)
x−15+15=−6+15(Add 15 to both sides)
x=9
Answer:
The third choice
Step-by-step explanation:
The third question is statistical because you can get a variety of answers from the different players. The other questions are only one answer and can not vary.
Answer:
0
Step-by-step explanation:
because we can't multiply anything by 0.
is like saying 0×0×0×0=0
Hope this helps :D
The answer you are looking for would be 2.
This can be found by solving with PEMDAS. First, you do the 4^2 (4*4), which equals 16. Next, you multiply 16 by 7, to get 112. Then, you'd divide 112 by 8. This gives you 14. Finally, subtract 12 from 14 to get your final answer of 2.
I hope this helps!
