Hannah wants to rewrite 18+12 using the greatest common factor and the distributive property. Which expression should she write?
grigory [225]

Answer:

6(3+2)

Step-by-step explanation:

Distributive property:

ab + ac = a(b+c)

where a = greatest common factor (GCF)

GCF of each factor

18 = 2×3×3

12 = 2×2×3

GCF of 18 and 12 = 2×3

= 6

Therefore,

18 + 12 = 6(3) + 6(2)

= 6(3+2)

Where,

6 = a

3 = b

2 = c

ab + ac = a(b+c)

joey can paint a room in 2 hours and chelsea can paint the same room in 3 hours. if they work together how long would it take to
JulijaS [17]

Answer:

1.2\ hours

Step-by-step explanation:

we know that

<em>Joey can paint a room in 2 hours</em>

That means

Joey can paint the 100% of the room-------> 2 hours

so

In 1 hour ------> can paint 100%/2=50%

<em>Chelsea can paint a room in 3 hours</em>

That means

C<em>helsea</em> can paint the 100% of the room-------> 3 hours

so

In 1 hour ------> can paint (100%/3)=33.33%

therefore

Joey and Chelsea in 1 hour can paint -----> 50%+33.33%=83.33%

by proportion

\frac{1}{83.33}\frac{hour}{\%} =\frac{x}{100}\frac{hour}{\%}\\ \\x=100/83.33\\ \\ x=1.2\ hours
