Answer:

15 years

Step-by-step explanation:

<u>Given:</u>

  • Number of trees = 167
  • This year limit = 4 trees
  • Yearly limit following years = 6 trees per year
  • Target number of trees = 50

<u>Building inequality:</u>

  • 167 - 4 - 8x < 50
  • 8x > 113
  • x > 113/8
  • x > 14.125

Adding current year to 14 we get 15 years as answer

Solve for w. 9 + 7w - 9 = 5w – 10 =​
777dan777 [17]

Answer:

w = -5

Step-by-step explanation:

Hello there!

9+7w-9=5w-10

Add 9 and -9 since we can add those

7w=5w-10

Use subtraction Prop of Equality (combining/simplifying like terms)

2w = -10

Now isolate the w by dividing 2w by 2 and use the division prop of equality

w = -5

Hope this helps. Feel free to comment for further explanation.

BEEN ASKING FOR A WHILE!! Find the perimeter and area for the triangle. Be sure to write the formula, and use correct measure. ​
Sauron [17]

Answer:

Area = 77ft²

Perimeter = 44 9/20 feets

Step-by-step explanation:

Area of a triangle = 1/2 * base * height

Base = 19 1/4 feets = 77/4 feets

Height = 8 feets

Area = 1/2 * 77/4 * 8

Area = (77 * 8) / 8

Area = 77 feet²

Perimeter of a triangle :

Sum of the sides

Perimeter = a + b + c

Perimeter = 19 1/4 + 10 + 15 1/5

Perimeter = 44 + (1/4 + 1/5)

Perimeter = 44 9/20

Find the distance between points A and B.
gladu [14]

Answer: OPTION D

Step-by-step explanation:

To solve this problem you must apply the formula for calculate the distance between two points, which is shown below:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

As you can see in the image, the coordinates of the points A and B are:

A(6,0)

B(4-3)

Then, when you substitute them into the formula, you obtain that  the distance between points A and B is:

 d=\sqrt{(6-4)^2+(0-(-3))^2}

d=\sqrt{13}\ units
