Ok so you got -30+2r=4(4r-4)
You distribute and get -30+2r=16r-16
Then you subtract 16r on both sides to get -30-14r=-16, then you add 30 on both sides and get -14r=14 then divide both sides by -14 to get r by itself, so the answer is r=-1
Yeah I’m pretty sure it’s d
Answer:
585$
Step-by-step explanation:
25% of 450$ is 112.5
5% is 22.5
add all of this to the 450 and you get the answer!
So from what I understand of the problem, the tv costs $850 at a discounted price of 20%. and other than the 20%, you can get an additional discount of 15% at the counter. So to solve this, you can just simply multiply 850 with 35% or 0.35. The answer to that will be $297.5. Now you then have to less this amount with 850. The final answer to that is 552.5. So after all the discounts that you have received from the store, then the final price that you can get for this tv set would be $552.5
B=4t
V=3t+6
they have the same amount of key chains when they equal
4t=3t+6
t=6
it would take 6 hours
