4x+8y=40
0.8*8=6.4
4x+6.4=40
40-6.4=33.6
4x=33.6
33.6\4=8.4
X=8.4

How to solve a equation like:<br> 2m = -2/3
adell [148]

Answer:

m = -\frac{4}{3}

Step-by-step explanation:

2m = -\frac{2}{3}

Divide both sides by 2 to get just m

\frac{2m}{2} = \frac{-\frac{2}{3}}{2}

You can't divide a fraction by a number so you do kcf (keep it, change it, flip it)

m = -\frac{2}{3} x \frac{2}{1}

m = -\frac{4}{3}

Determine the radius, to the nearest inch, of a large can of tuna fish that has a volume of 66 cubic
Mnenie [13.5K]

The radius of can is 2.524 inches

<em><u>Solution:</u></em>

Given that large can of tuna fish that has a volume of 66 cubic  inches and a height of 3.3 inches

To find: Radius

Given a large can of tuna fish, we know that can is generally of cylinder shape, we can use the volume of cylinder formula,

<em><u>The volume of cylinder is given as:</u></em>

\text{ volume of cylinder}= \pi r^{2} h$

Where,

"r" is the radius of cylinder

"h" is the height of cylinder

\pi is a constant equal to 3.14

Substituting the given values in above formula,

66 = 3.14 \times r^2 \times 3.3\\\\66 = r^2 \times 10.362\\\\r^2 = \frac{66}{10.362}\\\\r^2 = 6.369\\\\r = 2.524

Thus the radius of can is 2.524 inches
