Answer:

x = 4

Step-by-step explanation:

DE is parallel to AC and intersects the other 2 sides. It divides those sides proportionally, that is

$\frac{BD}{DA}$ = $\frac{BE}{EC}$ , thus

$\frac{10-x}{x}$ = $\frac{3}{2}$ ( cross- multiply )

2(10 - x) = 3x ← distribute left side

20 - 2x = 3x ( subtract 3x from both sides )

20 - 5x = 0 ( subtract 20 from both sides )

- 5x = - 20 ( divide both sides by - 5 )

x = 4

If ST=19 and S lies at -4 , where could T be located?

Natasha2012 [34]

Answer:

15 or -23

Step-by-step explanation:

I think you probably already turned this in but in case you haven't:

ST = 19 means that line segment ST is 19 units long. If we know that S is at -4, then T has to be 19 units away from -4, right?

So there's two directions we could go.

Add 19 to -4 to get 15, so T could be at 15. (If there's a line drawn between -4 and 15, it would be 19 units long.)

But the line could go left, towards negative infinity, too. So if we subtract 19 from -4, we'd get -23. T could also be at -23. (If there's a line drawn between -4 and -23, it would also be 19 units long. There's no such thing as a negative length.)

How many gallons of paint will you need in order to paint a wall that is 42 feet wide and 27 feet high if one gallon will cover

GREYUIT [131]

Answer:

42 x27 //// 1134 is the area

Step-by-step explanation:

1134/ 200= 5.67

You have to round up because you can’t get .67 of a paint bucket So you would have to round it out. About 6 buckets.

zysi [14]

Answer:

$157 m^{3}$

Explanation:

Volume = 1/3(area of base) times height. 1/3(PI X R(squared)) X height. 1/3 x 3.14 x 25 x 6 = 157

Hope this helps and have a great day/night!
