Okay! To do this, all you have to do is multiply the denominator and numerator by the same number. 

Let's take number 1 for example:

\frac{4}{10}

Choose a number that you want to multiply them by. I'm going to use the number 3. 

4 x 3= 12
10 x 3 =30 

So your equivalent fraction would be:
\frac{12}{30}

Note: Make sure you multiply the top and bottom by the same number. :)

Let me know if you need any more help with the other two.

Find the absolute maximum of m(t)=t^3-12t^2-144t and justify your answer​
ruslelena [56]

Answer:

Step-by-step explanation:

m(t)=t³-12t²-144t

Take the derivative of t:

t'=3t²-24t-144

Set it to 0:

3t²-24t-144=0

Solve for t:

t²-8t-48=0

(t-12)(t+4)=0

t=12 or -4

On a graph, you'll find that the maximum value occurs at t=-4 ..............

Matthew has $45 in savings and plans to save an additional $30 each month. How long will it take him to save enough for a $250 b
Semenov [28]

Answer:

Part A. It will take him 7 months

Part B. The equation is 30 - 45x + 250

Step-by-step explanation:

Part A. the answer is 7 because in 6 months Matthew will have $225 and if you add 30 you get $255.

Part B. It's the answer because its the only one that makes sense. 250 = 450 + 30. Its 45 not 450. 250 = 30.2 + 45. It's 30 not 30.2 and 30 30 well 30 30 doesn't make sense either.

P.S Can I have brainliest?

2+3x=-4(5+2x) solve for x, help please
Misha Larkins [42]

Answer:

x=-2

Step-by-step explanation:

2+3x=-4.(5+2x)

Expand  \: the  \: parentheses:

2 + 3x =  - 4.5 - 4.2x

Simplify \:  the \:  arithmetic:

2 + 3x =  - 20 - 4.2x

Solve \:  by \:  distributing:

2 + 3x =  - 20 - 8x

Group  \: all \:  x  \: terms \:  on \:  the  \: left  \: \\  side \:  of  \: the \:  equation

2 + 3x =  - 20 - 8x

Add  \: 8x \:  to  \: both \:  sides:

2 + 3x + 8x =  - 8x  + 8x

Simplify  \: the \:  arithmetic:

11x + 2 =  - 20 - 8x + 8x

Group \:  like  \: terms:

11x + 2 =  - 8x + 8x - 20

Group \:  all  \: constants \:  on \:  the \:  right  \\  \: side \:  of  \: the \:  equation

11x + 2 =  - 8x + 8x - 20

Subtract \:  2  \: from  \: both \:  sides:

11x + 2 -  =  - 20 - 2

Simplify \:  the  \: arithmetic:

11x =  - 20 - 2

Simplify  \: the \:  arithmetic:

11x =  - 22

Isolate \:  the \:  x

11x =  - 22

Divide  \: both \:  sides \:  by  \: 11:

\frac{11x}{11}  =  \frac{ - 22}{11}

Simplify \:  the \:  fraction:

x =  \frac{ - 22}{11}

Find  \: the \:  greatest \:  common \:  factor  \\  \: of  \: the  \: numerator \:  and  \: denominator:

x =  \frac{ - 2.11}{1.11}

Factor \:  out  \: and \:  cancel  \: the \:  greatest   \\ \: common \:  factor:

x =  - 2

Thanks!!!!!!!
