10 times the sum of half a number and 6 is 8

1 answer:

8 0

10 (x/2 +6)=8
10x/2 +60=8
Subtract 60 from both sides
10x/2+60-60=8-60
10x/2= -52
Multiply both sides by 2
(10x/2)*2= -52*2
10x= -104
Divide both sides by 10
10x/10=-104/10
Answer: x= -10.4

Please help me with pythagoras.

lana [24]

Answer:

(q)

$cb \: = \sqrt{4 {}^{2} + {3}^{2} }$

$cb = 5$

$q = \sqrt{ {13}^{2} - {5}^{2} }$

$q = 12$

(r)

$cb = \sqrt{ {13}^{2} - {5}^{2} }$

$cb = 12$

$r = \sqrt{12 {}^{2} - 5 {}^{2} }$

$r = \sqrt{119}$

$r = 10.91$

(s)

$ab = \sqrt{20 {}^{2} - 16 {}^{2} }$

$ab = 12$

$s = \sqrt{12 {}^{2} + 8 {}^{2} }$

$s = 4 \sqrt{13}$

$s = 14.42$

It takes 4/7 of an hour to paint 2/7 of a room. How long does it take to paint one room ?

Sidana [21]

Answer:

2 Hours

Step-by-step explanation:

4/7 of an hour = 34.3 minutes.

34.3 minutes per 2/7

4/7 = 68.6 OR 1 hour 8 minutes.

6/7 = 102.9 OR 1 hour 42 minutes.

Then add half of 34.3 (17.15)

7/7 = 120.05. = 2 hours 0.5 seconds.
