The percentage is given by

blondinia [14]
P is (18, -16)

to find the answer, u would solve it in reverse order of the midpoint formula by first doing the x-values:

5(2)= 10-(-8) = 18

and then the same to y-values:

-10(2)= (-20)-(-4) = -16

to get:

(18, -16)

Plzz help me helppppp I'm almost out of time
Evgen [1.6K]

Answer:

$6.50 per bag of popcorn

Step-by-step explanation:

let a bag of popcorn be represented by p and a candy bar be b

28p + 40b= $282

17p + 20b= $160.50

this is an example of stimatanelous equations

so you have to double the second equation to give 34p + 40b =$321

subtract the equations to give one

6p =$39

divide $39 by 6 to give the value of one bag of popcorn = $6.50

Dr. Brown did 6 experiments at 7AM. Dr. Rachal did 8 experiments at 6PM. They both had 564 tools each. Dr. Brown used 386 and Dr
devlian [24]

Answer:

Step-by-step explanation:

Total number of tools for both = 564.

Dr Brown used 386 tools for 6 experiments.

average number of tools per experiment used by Dr Brown = \frac{386}{6}

                                               = 64\frac{1}{3}

Dr Rachal used 236 tools for 8 experiments.

average number of tools per experiment used by Dr Rachal = \frac{236}{8}

                                                = 29\frac{1}{2}

i. The number of more experiment that can be done by Dr Brown = (564 - 386) ÷ (64\frac{1}{3})

                                 = 2.7668

Dr Brown can do two more experiments.

The number of more experiments that can be done by Dr Rachal = (564 - 236) ÷ (29\frac{1}{2})

                                  = 11.1186

Dr Rachal can do 11 more experiments.

ii. Number of tools left after Dr Brown's experiments = 564 - 386

                                                            = 178

Number of tools left after Dr Rachal's experiments = 564 - 236

                                                            = 328
