Answer:
-7/4
Step-by-step explanation:
1. Move -4 to the other side and make it a positive 4 so -3w=w+3+4
2. Simplify the side where the 4 is so -3w=w+7
3. Move the w to the other side so -3w-w=7
4. Simplify once again so -4w=7
5. Divide both sides by -4 so the answer would be w= -7/4
And if you want to check plug in -7/4 in both of the W spaces and see

Answer:
y = 2x - 22
Step-by-step explanation:
y = 2x + 1
Parallel slope: 2
(7, -8)
y - y1 = m(x - x1)
y + 8 = 2(x - 7)
y + 8 = 2x - 14
y = 2x - 22
The radius of can is 2 inches
<em><u>Solution:</u></em>
Given that, Can has a volume of 62.8 cubic inches
Height of can is 5 inches
To find: Radius of can
The can is of shape cylinder
<em><u>The volume of a cylinder can be found using the formula:</u></em>
![V = \pi {r}^{2} h](https://tex.z-dn.net/?f=V%20%3D%20%5Cpi%20%7Br%7D%5E%7B2%7D%20h)
Where, "r" is the radius and "h" is the height of cylinder
Substituting the values we get,
![62.8 = 3.14 \times r^2 \times 5\\\\62.8 = r^2 \times 15.7\\\\r^2 = \frac{62.8}{15.7}\\\\r^2 = 4\\\\\text{Take square root on both sides }\\\\r = 2](https://tex.z-dn.net/?f=62.8%20%3D%203.14%20%5Ctimes%20r%5E2%20%5Ctimes%205%5C%5C%5C%5C62.8%20%3D%20r%5E2%20%5Ctimes%2015.7%5C%5C%5C%5Cr%5E2%20%3D%20%5Cfrac%7B62.8%7D%7B15.7%7D%5C%5C%5C%5Cr%5E2%20%3D%204%5C%5C%5C%5C%5Ctext%7BTake%20square%20root%20on%20both%20sides%20%7D%5C%5C%5C%5Cr%20%3D%202)
Thus the radius of can is 2 inches
