5(x - 3) = 2(x + 6) + 3x

1 answer:

3 0

The first one is
5x-15=2x+12+3x
5x-2x-3x=12+15
0=27

The second one is
6.5x-7.75x=-12+14.5
-1.25x=-2.5
Divide both sides by - 1.25
X=. 02

The third one is
K-10=3
K=13
The second part of the third one is
-|k-10|=3
-k+10=3
-k=3+10
-k=13
Divide both sides by negative
K=-13

The fourth one is
4n+32=56
4n=56-32
4n=24
Divide both sides by 4
N=6
The second part to that one is
-4|n+8|=56
-4n-32=56
-4n=88
Divide both sides by - 4
N=22

The fifth one is
N+7-6=8
N=8-7+6
N=1+6
N=7
The second part to this one is
-|n+7|-6=8
-n-7-6=8
-n=8+7+6
-n=21
Divide both sides by negative
N=-21

The last one is
5x-7-3=9
5x=9+7+3
5x=19
Divide both sides by 5
X=19 over 5
The second part to this one is
-|5x-7|-3=9
-5x+7-3=9
-5x=9-7+3
-5x=5
Divide both sides by - 5
X=-1
I hope this helps you out.

Step-by-step explanation:

Answer

311=0.272727...............

311

= 3011×(110)

= 22+811×110

= 2211×110+811×110

= 2×110+8011×1100

= 210+77+311×1100

= 210+7711×1100+311×1100 or

311=210+7100+1100×(311) ........(A)

Now using value of 311 from (A) within (A)

311=210+7100+1100×(210+7100+1100×(311))

= 210+7100+21000+710000+110000×(311))

Now, if we keep on repeating this endlessly

311=210+7100+21000+710000

adoni [48]

Answer:

C. 22

Step-by-step explanation:

The problem statement tells you ...

missed = 24.6% × 90

= 0.246 × 90 = 22.14

The best estimate among the answers given is 22, choice C.

_____

Comment on the problem statement

The percentage given is supposedly computed from the number of shots attempted and missed this season. The ratio 22/90 would give a percentage rounded to 24.4%, not 24.6%.

24.4% of 90 is 21.96, closer to 22.

A total of $6000 was invested, part of it at 3% interest and the remainder at 8%. If the total yearly interest amounted to $380,

Nastasia [14]

$ 2000 is invested at 3 % interest and $ 4000 is invested at 8 % interest

Solution:

Given that, total of $6000 was invested

Let "x" be the amount invested at 3 % interest

Then, (6000 - x) is the amount invested at 8 % interest

Given that,

The total yearly interest amounted to $380

Then, we can frame a equation as:

$x \times 3 \% + (6000 - x) \times 8 \% = 380$

Solve the above expression for "x"

$x \times \frac{3}{100} + (6000-x) \times \frac{8}{100} = 380\\\\0.03x + (6000-x) \times 0.08 = 380\\\\0.03x + 480 - 0.08x = 380\\\\-0.05x = -100\\\\\text{Divide both sides by -0.05 }\\\\x = 2000$

Thus, $ 2000 is invested at 3 % interest

(6000 - x) = 6000 - 2000 = 4000

$ 4000 is invested at 8 % interest
