The answer is 854 for sure. I did the test and got it all right.
Answer:
u just have to cross multiply im pretty sure thats how my math teacher show me,
Step-by-step explanation:
first you take the one x over to the other x and that will make it 2x then do the same thing with -10 u do -10 times 10 and then u get -100 and then the answer is 2x-100 and depending on your teach if he/she wants you to stop their then u can but if u have to got further then u would divide 2 on both sides and then that would be 0.02
this is how my teacher showed us how to do it and i hope this helps you a lot and if it dont im sorry i tried for you!!!
have a nice day Hun
A] Given that the last years's sales was $144,600 and this years sales should increase by 1/3. Then:
i] Amount the sales should increased by will be:
(last year's sales)*(increase)
=144,600*(1/3)
=48,200
ii] The sales in the new year will be:
(last year's sales)+(increase)
=144600+48600
=$192, 800
2] Given that the sales of hifi which included 6% tax was 205,000. The actual sales was:
Actual percentage sales=100%
percentage sales after taxation=100-6=94%
thus the actual sales was:
(100)/(94)*205,000
=218, 085.1064
3]Given that the rate per $100 is $0.83, and the insurance was for 90000, the insurance premium will be:
(total insurance) *(unit rate)/(number of units)
plugging the values we obtain:
90000*0.83/100
$747
Answer: Infinite solutions.
Step-by-step explanation:

Plug the value of y into the second equation.

Add 12 on both sides.

Add 4x on both sides.
