Answer:
x=5/13
Step-by-step explanation:
2/3+7/2=9x+5/6+4x
2/3+7/2-5/6=9x+4x
lcm of 2,3,6=6
2/3=4/6 7/2=21/6 5/6=5/6
4/6+21/6-5/6=9x+4x
30/6=13x
5=13x
x=5/13
You could use simple factoring to solve this. You would factor out a 7 and then have
7(3+4m) = A
l x w = A
w= 3 +4m
Answer:
1. Technically 2, but might be 0 in your teacher's opinion.
2. 1
Step-by-step explanation:
Solving problem one.
So I don't know if you have learned about imaginary numbers, but if you have, then you would end up with two answers if you plugged in the quadratic formula.
If you haven't learned about imaginary numbers, then I would say your best option would be to write 'No real solution' since there are technically 2 solutions.
Solving problem two.
Turns out this quadratic has a special property and it's actually a square of one equation. You can find out by just factoring the equation.
It's (3x-2)^2. Since it's squared, that means that only 2/3 would work as x in this equation.
Answer:
The Quantity 10$ per shirt represent a unit rate .
Step-by-step explanation:
Given:
There are 3 white shirts and 2 black shirts . per 10$ dollar.
To find:
Which quantities represent the unit rate ?
Solution:
Total of 5 shirts .
which means total of 50 dollar among 5 shirts.
i.e.50/5=10 dollars .
Hence each shirt causes 10 dollars or 10$ per shirt.
The Quantity 10$ per shirt represent a unit rate .
