Answer:

5n + 4m + 4

Step-by-step explanation:

You can't do anything to the coefficients 5n and 4m, since they both have their own variable. But, you can add 1 and 3 since they're by themselves without any variable. Hope this helps.

Answer: 4m + 5n + 4

Let's solve your problem step by step:

You need to combine like terms:

1 + 5n + 3 + 4m

= (4m) + (5n) + (1+3)

= 4m + 5n + 4

After you have combined like terms you are left with 4m + 5n + 4

Amelia and Elliott are collecting empty soda cans for recycling. Amelia has 13 less than 5 times the cans that Elliott has. Toge

sleet_krkn [62]

ANSWER

Find out the how many cans does each one have.

To proof

As given

Amelia and Elliott are collecting empty soda cans for recycling

Amelia has 13 less than 5 times the cans that Elliott has.

let us assume that the Elliott has can be =x

Amelia can = 5x -13

Total can = 257 cans

than the equation becomes

x + 5x - 13 = 257

6x = 257 +13

6x = 270

x = 45

Elliott has can be = 45cans

Amelia can = 5 × 45 - 13

= 212cans

Hence proved

How many cubes with side lengths of 1/3 cm does it take to fill the prism?

user100 [1]

Answer:

The number of cubes that fill the prism is 24

Step-by-step explanation:

Given as :

The length of cube (l) = $\frac{1}{3}$ cm

The length of prism (L) = 1 cm

The width of prism (w) = 2 $\frac{2}{3}$ = $\frac{8}{3}$ cm

The height of prism (h) = $\frac{2}{3}$ cm

Let the number of cubes that fill the prism = x

Now, Volume of cube with length (l) = l³ cm³

Or, Volume of cube with length (l) = $(\frac{1}{3})^{3}$ cm³

Or, Volume of cube with length (l) = $(\frac{1}{27})$ cm³

Again , Volume of prism = $\frac{1}{2}\times Length \times width \times height$

Or, Volume of prism = $\frac{1}{2}\times 1 \times \frac{8}{3} \times \frac{2}{3}$

Or, Volume of prism = $(\frac{8}{9})$ cm³

<u>So , The number of cubes to fill prism </u>

The number of cubes × Volume of cube = Volume of prism

Or, x × $(\frac{1}{27})$ cm³ = $(\frac{8}{9})$ cm³

or x = $\frac{8\times 27}{9}$ = 24

Hence The number of cubes which fill the prism is 24 Answer

A sports ball has a diameter of 27 cm. Find the volume of the ball. cm.) Round your answer to the nearest tenth if necessary.

Anestetic [448]

To calculate the volume of a sphere you must use the formula
v=4/3pir^3

The radius (r) is half of the diameter
r=13.5

v=4/3pi13.5^3
v=10305.99

Therefore the volume of the sports ball is 10306cm^3 (to the nearest tenth)
