P=2(l+w)
Substitute width plus 3 for length
Remember order of operations: multiply before adding

86=2((w+3) + w)
86=2w+6+2w
86=4w+6
80=4w
20=w
23=w+3=l

Check the answer
86=2((w+3) + w)
86=2((20+3)+20
86=2(23+20)
86=46+40
86=86

A clerical worker takes 2 times as long to finish a job as it does an executive secretary. Working​ together, it takes them 6 hr
malfutka [58]

Answer:

<h2>18 hours</h2>

Step-by-step explanation:

This problem is on Combined work rate

Step one:

given data

let the secretary take x hours to finish one job

so the clerical worker will take 2x hours to finish one job.

Both of them working together will take 6 hours

Step two:

The combined work formula is

T/A+T/B=1

Where T= time working together

A= time the Clerical worker spent alone

B= time the secretary spent alone

substituting we have

6/2x+6/x=1

solve for x

6+12/2x=1

18/2x=1

9/x=1

cross multiply

x=9 hours

the clerical worker take 2x hours

2*9= 18 hours

About 9/10 Of the avocados grown in the United States are in California about what percent of our car is going in the United Sta
artcher [175]

Answer:

9/10 x 100% = 90%

Step-by-step explanation:

The question is asking us to convert the given fraction, 9/10, to percentage. As we know, to convert any number to percentage, we simply multiple by 100%. We are not changing the value because 100% means 100/100 = 1. So, we are basically multiplying by 1.

Since we are told that 9/10 avocados grown in the US are grown in California, then the percentage would be:

9/10 x 100% = 90%

rodikova [14]

Answer:

Interest will amount to $142.58

Total amount Levi will have to pay back at the end of 6 months=$7271.58

Interest will amount to $142.58

Total amount Levi will have to pay back at the end of 6 months

=$7129+$142.58

=$7271.58
