Please help me with this

Sati [7]

Answer:

$x = \sqrt{11.4^2+2.6^2}\\\\$

Rounded to the nearest hundredths: 11.69.

Step-by-step explanation:

I would use the Pythagorean theorem for this problem.

The difference between the highest point and the lowest point of AD is 9.8-7.2 = 2.6, so that would be the height of the triangle. The length/base of the triangle would be 11.4.

Now, just solve using Pythagorean's theorem:

$x = \sqrt{11.4^2+2.6^2}\\\\$

Rounded to the nearest hundredths: 11.69.

I hope this helped you.

1) solve for w: 3w - 10 = 4w + 5<br> 2) solve for t:6 -2t >18

Gre4nikov [31]

Problem # 1
3w-10=4w+5
(3w-10) + (10-4w) = (4w+5) + (10-4w)
(3w-10) + (-4w+10) = (4w+5) + (-4w +10)
3w-10-4w+10 = 4w +5 -4w +10
3w-4w=15
-w=15
w= -15 (w is negative 15)

problem #2.
6-2t > 18
6-2t-6 > 18-6
-2t > 12
(-1) (-2t) > 12 (-1)
2t > -12
next divide by 2
2t/2 > -12/2
t > -6 (t is greater then negative 6)
