7x=21

Write a multiplication equation and a division equation that this diagram could represent.
vivado [14]

Answer:

3 * 18= 54 and 54/18 = 3

Step-by-step explanation:

Given

Sections = 3

Measurement=18 per section

Total\ Measurement=54

Required

Divide both sides by 18

3 * 18/18 = 54/18

3 * 1 = 54/18

3 = 54/18

Reorder

<em />54/18 = 3<em> -- This represents the division model</em>

FromTheMoon [43]

Answer:

No, because 1.25% times 3 is 3.75% which is less than 6%

Step-by-step explanation:

Quarterly is every 3 months

6% interest is 1.06, 6 cents on the dollar

Monthly interest rate is 1.25% so 1.25 × 3 is 3.75

So, 1.25% times 3 is 3.75% which is 2.25% less than 6%

Hope this helps!

Have a great day!
