Answer:

#5 x=8, #6 x=5

Step-by-step explanation:

Theyre vertical so for number 5 you would have the equation

5x+15=55

-15 -15 from both sides

5x=40

divide by 5 from both sides and you get

x=8

Same thing vertical so you would have

16x+7=87

-7 -7 from both sides

16x=80

divide by 16 from both sides

x=5

7/9 - 4/3w = -5/6 <br> what is w

borishaifa [10]

Answer:

w=1 5/24

Step-by-step explanation:

7/9-4/3w=-5/6

-4/3w=-5/6-7/9

-4/3w=-15/18-14/18

-4/3w=-29/18

w=-29/18:(-4/3)

w=29/18*(3/4)

w=29*3/18*4

w=29/6*4

w=29/24

w=1 5/24

The area of a rectangular horse pasture is 268,500 square yards. The length of the pasture is 5 yards less than three times the

Setler79 [48]

Answer: width = 300

<u>Step-by-step explanation:</u>

Area (A) = Length (L) x width (w)

Given: A = 268,500

L = 3w - 5

w = w

268,500 = (3w - 5) x (w)

268,500 = 3w² - 5w

0 = 3w² - 5w - 268,500

0 = (3w + 895) (w - 300)

0 = 3w + 895 0 = w - 300

-985/3 = w 300 = w

Since width cannot be negative, disregard w = -985/3

So the only valid answer is: w = 300
