Two integers a and b, have a product of 24. What's the least they can be?
xxTIMURxx [149]
Well think, 24= 8x4  right? So, 2 can go into 24 which=12 so lets divide.
24÷2= 12
12÷2=6
6÷2=3
3 is the smallest we can get so can 3 go into 24? yes, so 8 times 
so the smallest they can be are 8*3 and you cant reduce 8 anymore because of the three once one gets the smallest they both do. hope this helped.

Marian buys a dress that costs $32.00 She pays 10%<br> sales tax
Travka [436]

Answer:

$35.2

Step-by-step explanation:

I’m assuming you meant the total of the dress after tax.

1. 32 * 1.1 = 35.2

OR

1. 32 * 0.1 = 3.2

2. 32 + 3.2 = 35.2

You could do it either way.

Jeff takes 5 hour longer to build a fence than it takes bill. when they work together, it takes them 6 hours. how long would it
kobusy [5.1K]
Best Answer: Bill's time to do the whole job, B
Jeff's time, B + 5
time they actually work, 6.

6/B + 6/(B+5) = 1
6(B+5) + 6B = B(B+5)
6B + 30 + 6B = B² + 5B
B² - 7B - 30 = 0
(B - 10)(B + 3) = 0
B = 10 or B = -3, and we reject the negative solution.

the equation is based on adding the fractions of the whole job each does. if Bill takes B hours to do the whole thing and works 6, he does 6/B of the job. similarly for Jeff.

in the 2nd problem,
a = time of experienced accountant
2a = time of new accountant
10 = time each actually works

10/a + 10/(2a) = 1 ........ multiply all by a
10 + 5 = a
a = 15 hr.

What is this question for math 2/12+1/3
Alexxandr [17]

Answer: 1/2

<u>Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD</u>

(2/12*1/1) + (1/3+4/4)

<u>Complete the multiplication and the equation becomes </u>

2/12+4/12

<u>The two fractions now have like denominators so you can add the numerators.</u>

2+4/12 = 6/12

<u>This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor </u>

6/12 ÷ 6/6 = 1/2

<u>Therefore: </u>

2/12 + 1/3 = 1/2
