What is x/13-5=25/26

1 answer:

Juliette [100K]3 years ago

$\frac{x}{13} -5=\frac{25}{26}$ Add 5 on both sides

$\frac{x}{13}=\frac{25}{26}+5$ Make the denominators the same

$\frac{x}{13}=\frac{25}{26}+\frac{130}{26}$

$\frac{x}{13}=\frac{155}{26}$ Multiply 13 on both sides

$(13)\frac{x}{13}=(13)\frac{155}{26}$

$x=\frac{2015}{26}$

$x=\frac{155}{2}$

What is the factored form of the expression?<br><br> d^2 = 36d + 324

Veseljchak [2.6K]

Answer:

$(x-43.45)(x+7.45)=0$

Step-by-step explanation:

We have the quadratic equation $d^{2}=36d+324$ i.e. $d^{2}-36d-324=0$

As, the roots of the quadratic equation $ax^{2}+bx+c=0$ are given by $x=\frac{-b\pm \sqrt{b^{2}-4ac}}{2a}$ .

So, from the given equation, we have,

a = 1, b = -36 , c = -324.

Substituting the values in $x=\frac{-b\pm \sqrt{b^{2}-4ac}}{2a}$ , we get,

$x=\frac{36\pm \sqrt{(-36)^{2}-4\times 1\times (-324)}}{2\times 1}$

i.e. $x=\frac{36\pm \sqrt{1296+1296}}{2}$

i.e. $x=\frac{36\pm \sqrt{2592}}{2}$

i.e. $x=\frac{36\pm 50.9}{2}$

i.e. $x=\frac{36+50.9}{2}$ and $x=\frac{36-50.9}{2}$

i.e. $x=\frac{86.9}{2}$ and $x=\frac{-14.9}{2}$

i.e. x = 43.45 and x = -7.45

Thus, the roots of the equation are 43.45 and -7.45.

Hence, the factored form of the given expression will be $(x-43.45)(x+7.45)=0$

Need help ASAP. Thanks!

Answer: 114

Step-by-step explanation:

To find the perimeter, you will find the distance around the shape by adding the numbers.

The is one missing side and to find that side you will subtract 10 from 38.

38 - 10 = 28

Now add the them.

28 + 5 + 10 + 26 + 10 + 35 = 114

kate takes 48 minutes to get to the park. if she gets to the park at 2:32 what time did she leave for the park

olya-2409 [2.1K]

Answer:

1:44

Step-by-step explanation:

You can subtract 32 minutes from 2:32 to get 2:00.

Since you only subtracted 32, subtract 16 (16+32=48) from 60, since 60 minutes is one hour, to get 1:44
