Answer:

m = 2600

Step-by-step explanation:

0.12m = 78 + 0.09m

0.12m - 0.09m = 78 + 0.09m - 0.09m

0.03m = 78

m = 2600

Make sure to double check!

2600 x 0.12 = 78 + 0.09 x 2600

312 = 78 + 234

312 = 312

Answer:

(Assuming the . means its a decimal...)

Step-by-step explanation:

Rewrite equation

0.12m = 78 + 0.09m

Multiply each side by 100

12m=7800 + 9m

Subtract 9m on both sides

12m-9m=7800+9m-9m

3m=7800

Divide both sides by 3

m = 2600

Hope this helps :)

Romashka-Z-Leto [24]

Answer:

9.8 inches

Step-by-step explanation:

<h3>Formula for volume of the sphere is = 4/3πr³</h3><h3>Form and solve the equation for the radius</h3><h3>So: 4/3πr³= 498in³</h3><h3>πr³= 498in³*3/4 which = to 373.5in³</h3><h3>r³= 373.5in³/π</h3><h3>r=∛(373.5in³/π)</h3><h3>calculate r and times the result by 2 for diameter</h3><h3>it will be 9.834...</h3><h3>nearest tenth of an inch means the accuracy is 1 decimal place because nearest tenth= 1/10 or 0.1</h3><h3>So the final answer is 9.8in</h3>
