I really need help on this question! Thank you!

KIM [24]

Answer:

A

Step-by-step explanation:

We know the following:

$OE=5\\\\FG=4\\\\EF=8\\\\$

so the segment EF is equal to

$EF=EG+GO+OF\\\\$

and here we can do a trick :)

$EF=(EG+GO)+GO+(OF+OG)-2GO\\\\$

you see it's the same

$EF=EO-GO+FG\\\\$

now we plug the values given

$8=5-GO+4\\\\8=9-GO\\\\GO=9-8\\\\GO=1$

so it's option A

Simplify (2/5÷3/8)÷(-3/5)

liberstina [14]

Answer:

$\pink{ - 1 \frac{7}{9} }$

Step-by-step explanation:

$( \frac{2}{5} \div \frac{3}{8} ) \div ( - \frac{3}{5} ) \\ (\frac{2}{5} \times \frac{8}{3} ) \times ( - \frac{5}{3} ) \\ \frac{16}{15} \times - \frac{5}{3} \\ - \frac{80}{45}$

As the answer can be more simplified, divide both numerator and denominator by 5.

$- \frac{16}{9} = - 1 \frac{7}{9}$

Substitute each given value of the variable to find which, if any, is a solution of inequality.

OlgaM077 [116]

Given:

The inequalities are:

a) $w$

b) $t>-25, t=-24, -25, -25.1, -27$

To find:

The solution of inequalities by substituting the given values.

Solution:

a) We have,

$w$

After substituting the given values one by one, we get

$-4.3$ False statement.

$-5.3$ False statement.

$-8.3$ True statement.

$-9$ True statement.

Therefore the solutions of $w$ are $w=-8.3, -9$ .

b)

We have,

$t>-25, t=-24, -25, -25.1, -27$

After substituting the given values one by one, we get

$-24>-25$ True statement.

$-25>-25$ False statement.

$-25.1>-25$ False statement.

$-27>-25$ False statement.

Therefore, the solution of $t>-25$ is $t=-24$ .
