Answer:

-3

Step-by-step explanation:

According to the question,

$\longrightarrow$ CE = CD + DE

$\longrightarrow$ 8 = (x + 10) + (x + 4)

$\longrightarrow$ 8 = x + 10 + x + 4

$\longrightarrow$ 8 = 2x + 14

$\longrightarrow$ 8 ― 14 = 2x

$\longrightarrow$ ―6 = 2x

$\longrightarrow$ ―6 ÷ 2 = x

$\longrightarrow$ –3 = x

Therefore, the value of x is ― 3.

JulsSmile [24]

Answer:

Range A = 386ft

Range B = 427ft

B has the larger range.

Explanation:

To find the range, find the difference between the minimum and maximum depths for each submarine. Remember that your answer will be positive.

Sub A:

-146ft - (-532ft) = 386 ft

Sub B:

-194ft - (-621ft) = 427 ft

Submarine B has a larger range.

Help plz (problly easy for you)

PolarNik [594]

The second option: 4x² - x + 1

All you have to do is add the like terms:

3x² + x² = 4x²

4x - 5x = -x

-2 + 3 = 1

Combine all the results and you will get your solution!

What is 18 divided by 2/3?

pishuonlain [190]

Division is basically
x divided by y=x/y so
18 divided by 2/3= $\frac{18}{ \frac{2}{3} }$
we want the bottom number to be =1 so we multiply 2/3 by 3/2 to make it 1 (or 6/6=1), but we have to multiply the top number by 3/2 also so that we don't change the fraction and make our work useless so

$\frac{18}{ \frac{2}{3} } times \frac{ \frac{3}{2} }{ \frac{3}{2} } = \frac{ \frac{54}{2} }{ \frac{6}{6} }= \frac{27}{1}=27$
