Apharmaceutical company is testing two treatments, a and b, that are used to heal wounds. they test the effectiveness of treatment a by applying it on an area of a 1 square inch wound. it heals by decreasing the area of the wound at a rate of 5.5% per day. they then test the effectiveness of treatment b by applying it on an area of a 2 square inch wound. it heals by decreasing the area of the wound at a rate of 12.4% per day. the equation below can be used to determine the number of days, x, it will take for the area of the wounds to be equal rounded to the nearest day, approximately how long will it be for the area of the wounds to be equal? e-0.055x=2e-0.124x

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
