Answer:

-5

Step-by-step explanation:

The dot means multiply:  so 3 \cdot 2 = 3 \times 2 = 6

Also:  5² = 5 x 5 = 25

Therefore,

-6-4(3 \cdot 2)+5^2

\implies -6-4(6)+25

\implies -6-(4 \times 6)+25

\implies -6-24+25

\implies -5

- 6 - 4(3 \times 2) +  {5}^{2}

*Note:- The dot represents the multiplication symbol

\to - 6 - 4 \times 6 +  {5}^{2}

\to - 6 - 4 \times 6 + 25

\to- 6 - 24 + 25

\to - 30 + 25

\boxed{ \sf \: ans =  - 5}

Claire mowed 4 lawns last week. She mowed each lawn in startfraction 7 over 27 endfraction hour. She mowed the same lawns this w
maw [93]

Claire's time to mow all the lawns last week was 1.4 times longer than this week.

<em><u>Explanation</u></em>

Claire mowed each lawn in \frac{7}{27} hour last week.

So, the <u>total time taken to mow all 4 lawns last week</u> =\frac{7}{27}*4=\frac{28}{27} hours.

She mowed the same lawns this week and took \frac{5}{27} hour for each.

So, the <u>total time taken to mow all 4 lawns this week</u> =\frac{5}{27}*4=\frac{20}{27} hours.

Now.....

<u><em>(Total time in last week / Total time in this week)</em></u><em>  </em>=\frac{(\frac{28}{27})}{(\frac{20}{27})} = \frac{28}{20}=\frac{7}{5}=1.4

So, Claire's time to mow all the lawns last week was 1.4 times longer than this week.
