3(2y-4) - 2 ) = 0.4 (1+y)

Answers

Answer 1

Answer: 6y-12-2=0.4+0.4y
6y-10-0.4=0.4-0.4+0.4y
6y-6y-9.6=0.4y-6y
(-9.6=-5.6y)/5.6
1.7143=y

To simplify each expression and use positive exponents for m^3n^-6p^0.

Answers

$m^(3n) -6 p^(0)$
= $m^(3n) -6$

$m^3n^-6p^0$

$Use \ Negative \ Power \ Rule$ $x^-^a= (1)/(x^a)$

$m^3* (1n)/(6) p^0$

$Use \ Rule \ of \ Zero$ $x^0=1$

$m^3*1 (1)/(n^6) *1$

$\boxed{\boxed{(m^3)/(n^6)}}$ $Solution$

Erika and Bradley want to hike the Big Cypress Trail. They will hike a total of 72 milles FErika and Bradley want to hike 16 miles each day, how many days will they hike exadty 16 miles? They will hike exactly 16 miles each day for days.

Answers

Answer: They will hike exactly 16 miles each day for 4 days.

Step-by-step explanation:

Given: Total distance to hike = 72 miles

They hike 16 miles per day.

Total days they will take to complete the distance = $\frac{\text{Total distance to hike}}{\text{Distance hiked each day}}$

$=(72)/(16)\n\n=(9*8)/(2*8)=\frac92\n\n=4\frac12$

It will take 4 complete days and a half day to complete the journey.

i.e. They will hike exactly 16 miles each day for 4 days.

Jose wants to find the perimeter of triangle ABC. He uses the distance formula to determine the length of AC. Finish Jose’s calculations to find the length of AC.What is the perimeter of triangle ABC? Round the answer to the nearest tenth, if necessary.

12.0 units
12.4 units
15.0 units
15.4 units

Answers

AC = √ (-5)² + (4)²
AC = √ 25 + 16
AC = √41
AC = 6.40 This is the measure of the hypotenuse.

long leg = 5 distance from -2 to +3 (x - axis)
short leg = 4 distance from 2 to 6 (y - axis)

perimeter = 6.4 + 5 + 4 = 15.4 units
