Can someone plzzz hekppp meeee
erastova [34]

Answer:

Use this formula for these kinda things.

Step-by-step explanation:

Remember The z is the hypathonous, it means the biggest side.

{a}^{2}  +  {b}^{2}  =  {c}^{2}

where Z is going to be C

put this all together

{7}^{2}  +  {18}^{2}  =  {z}^{2}

put it into calculator, means 373=

{z}^{2}

therfore take the square root, it will be

z =  \sqrt{373}

which it will be 19.31

Rachel saved money to buy art supplies. She used 13 of her savings to buy brushes. She used 35 of her savings to buy paint. What
vekshin1

Given:

Rachel used \dfrac{1}{3} of her savings to buy brushes.

She used \dfrac{3}{5} of her savings to buy paint.

To find:

The fraction for remaining savings.

Solution:

Fraction that Rachel used of her savings to buy brushes and paint is

\text{Fraction for used amount}=\dfrac{1}{3}+\dfrac{3}{5}

                                    =\dfrac{5+9}{15}

                                    =\dfrac{14}{15}

Now,

\text{Fraction for remaining savings}=1-\text{Fraction for used amount}

\text{Fraction for remaining savings}=1-\dfrac{14}{15}

\text{Fraction for remaining savings}=\dfrac{1}{15}

Therefore, \dfrac{1}{15} of her savings is remaining.

If twice a number is subtracted from 11, the result is 4 more than the number. What is the number?
Flauer [41]

Let the number = x.

So 2 times x subtracted from 11 is written as 11-2x

The result is 4 more than the number is written as 4 +x

Now you have 11-2x = 4 + x

We can now solve for x.

Add 2x to each side:

11 = 4 + 3x

Subtract 4 from each side:

7 = 3x

Divide both sides by 3:

x = 7/3
