Answer: x=5/3

Step-by-step explanation:

For this problem, you want to solve for x. You first distribute, get all like terms to one side, and then sovle for x.

2(x+3)=5(x-1)+6

2x+6=5x-5+6.    (combine like terms)

2x+6=5x+1         (move all like terms to one side)

5=3x                   (divide to solve for x)        

x=5/3

WILL GIVE BRAINLIEST FOR BEST ANSWER I NEED THIS NOW! THANK YOU!

What we know:
Football field is 100 yards in length
End zones are 10 yards each in length
Perimeter between pylons is 306 2/3 yards

What we need to find:
a. Perimeter and area of one end zone
b. Perimeter and area of without end zones
c. Perimeter and area of playing field with end zones

First we need to find the measurements of the field between pylons using the perimeter of 306 2/3 yards. We already know the length is 100 yards so we need to find width (w).

P=2l + 2w
306 2/3=2 (100) + 2w
306 2/3= 200 + 2w
300 2/3-200=200-200+2w
106 2/3=2w
106 2/3/2=2/2w
53 1/3=w

a. Perimeter=2 (10)+2 (53 1/3)=126 2/3 yards
Area=10×53 1/3=533 1/3 yd²
b. Perimeter=2 (100)+2 (53 1/3)=306 2/3 yards
Area=100×53 1/3=5333 1/3 yd²
c. Perimeter=2 (120) + 2 (53 1/3)=346 2/3 yards
Area=120×53 1/3=6400 yd²

Any altitude of an equilateral triangle is also a median of the triangle true or false ?

Evaluate ab when a=3 and b=-1.
Elena L [17]

Answer: -3

Step-by-step explanation:

ab just means a multiplied by b.

So just plug in the values for the variables to get 3 * -1 which equals -3.

I need help with steps of solving this equation.
saveliy_v [14]

Answer:

x = {-1/5, 1}

Step-by-step explanation:

(5x - 2)² - 1 = 8

Add 1 to both sides

(5x - 2)² = 9

Take the square root of both sides

5x - 2 = ±3

------------------------------

<u>Solution I</u> for 5x - 2 = +3

5x - 2 = 3

add 2 to both sides

5x = 5

Divide both sides by 5

x = 1

------------------------------

<u>Solution II</u> for 5x - 2 = -3

5x - 2 = -3

add 2 to both sides

5x = -1

Divide both sides by 5

x = -1/5

-------------------------------

x = {-1/5, 1}
