Answer:
w = 5
Step-by-step explanation:
Combining like terms is a very important part to this equation!
<em>5.2w - 1.4 = 3.2w + 8.6</em>
<em>I added 1.4 to the right side first, though you must do it to the left side of the equation as well</em>
<em>5.2w - 1.4 + (1.4) = 3.2w + 8.6 + (1.4)</em>
<em>5.2w = 3.2w + 10</em>
<em>Combine the remaining like terms. I subtracted 3.2w from both sides. </em>
<em>5.2w + (-3.2w) = 3.2w + (-3.2) +10</em>
<em>2w = 10</em>
<em>Now divide</em>
<em>2w = 10</em>
<em>w = </em><em />
<em>w = 5</em>

4/5-(-2/8)= 4/5+2/8 On taking LCM = 42/40= 21/20
Answer:
144 carrots
Step-by-step explanation:
Let C stand for the number of carrots that a student can plant.
We are told that carrots may be planted at a density of 9 carrots/ft^2.
Let A be the area, in ft^2, that can be planted with carrots. The area of a rectangle is Base x Length (in feet).
We can therefore write:
C = (9 carrots/ft^2)*A
In the garden shown, the area is A = (4 ft) x (4 ft) = 16 ft^2
C = 9 carrots/ft^2)*(16 ft^2)
C = 144 carrots
Answer:
14
Step-by-step explanation:
Given:
diameter of circle x = 22 units
diameter of circle y = 16 units
wx = 15 units
Want to find: length of xy
First, I started out by halving the diameters to get to the length of the radii, as that's what was depicted in the problem:
circle x: 22/2 = 11
circle y = 16/2 = 8
Now, you just strategically add..
5 + (11-5) + (8-5)
5 + 6 + 3 = 14 units
