It’ll take 3 days to paint the house together
Daniel [21]2 years ago

Answer:

1/6 + 1/5 = 1/x,  3 days

Step-by-step explanation:

a) x days will take to paint the house together.

b) 1/6 part of the house, Noah paints for 1 day.

1/5 part of the house, Owen paints for 1 day

1/x part of the house they paint for 1 day together, and also we can write that

(1/6 + 1/5) part of the house they paint for 1 day together.

So, we can write equation

1/6 + 1/5 = 1/x

c) 1/6 + 1/5 = 1/x

30x*1/6 + 30x*1/5 = 30x*1/x

5x + 6x = 30

11x = 30

x = 30/11 ≈2.72 ≈ 3 days

i need help with my math :( im horrable with it i cant do divideing fractions nor multiply and i dont know most of my multiples
vladimir1956 [14]

Step-by-step explanation:

To multiply the fractions, like

\frac{1}{4}  \times  \frac{1}{9}

Multiply the top,

then multiply the bottom.

\frac{1}{4}  \times  \frac{1}{9}  =  \frac{1 \times 1}{4 \times 9}  =  \frac{1}{36}

Try to use a calculator if you aren't arithmetic heavy, but I suggest you to try to remember them because they are going to be helpful for courses like Algebra, Calculus, Statistics, etc.

To divide fractions, like

\frac{ \frac{1}{5} }{ \frac{1}{8} }

You take the top number,

\frac{1}{5}

Then you flip the bottom number,

\frac{8}{1}

Then multiply the two

\frac{1}{5}  \times  \frac{8}{1}  =  \frac{8}{5}

And that is your answer. Comment if you need more clarification

Can someone help me?
Pani-rosa [81]

Answer: m=−3

Step-by-step explanation: −40−2(3m+1/2)=7m−2

−40+(−2)(3m)+(−2)(1/2)=7m+−2

−40+−6m+−1=7m+−2

(−6m)+(−40+−1)=7m−2

−6m+−41=7m−2

−6m−41−7m=7m−2−7m

−13m−41+41=−2+41

−13m/−13=39/−13

m=−3

What mistake I guess Keith did make is he subtracted 2 from -39 which equaled to -37 which caused him divide -37 by 13 when it should have been 39 divided by 13 because he should have left 39 alone and not have subtracted 2 from it also it should not have been negative basically what I'm trying to say is that he did his division and subtraction wrong.
