Answer:

[tex]4(a + 2) - 2(a - 8) = 24 \\ 4a + 8 - 2a + 16 = 24 \\ 2a + 24 = 24 \\ 2a = 24 - 24 \\ a = \frac{0}{2} \\ \\ a = 0[/tex]

Answer:

4

Step-by-step explanation:

Given:

The ratio is shirts to pants 3:2.

That means for every 3 shirts, there is 2 pairs of pants.

Therefore, your answer would be 4.

You can cross multiply for this problem. So:

[tex]\frac{6}{10}=\frac{21}{K}\\6K=210\\K=35[/tex]

So K=35!

Answer:

ʕ•ﻌ•ʔʕ•ﻌ•ʔʕ•ﻌ•ʔʕ•ﻌ•ʔʕ•ﻌ•ʔʕ•ﻌ•ʔ

Step-by-step explanation:

Let +a+ = liters of 40% solution needed

Let +b+ = liters of 25% solution needed

+.4a+ = liters of HN03 in 40% solution

+.25b+ = liters of HN03 in 25% solution

------------------------------------

(1) +%28+.4a+%2B+.25b+%29+%2F+57+=+.26+

(2) +a+%2B+b+=+57+

-----------------

(1) +.4a+%2B+.25b+=+.26%2A57+

(1) +.4a+%2B+.25b+=+14.82+

(1) +40a+%2B+25b+=+1482+

Multiply both sides of (2) by +25+

and subtract (2) from (1)

(1) +40a+%2B+25b+=+1482+

(2) +-25a+-+25b+=+-1425+

+15a+=+57+

+a+=+3.8+

and, since

(2) +a+%2B+b+=+57+

(2) +3.8+%2B+b+=+57+

(2) +b+=+53.2+

3.8 liters of 40% solution are needed

53.2 liters of 25% solution are needed

check:

(1) +%28+.4a+%2B+.25b+%29+%2F+57+=+.26+

(1) +%28+.4%2A3.8+%2B+.25%2A53.2+%29+%2F+57+=+.26+

(1) +%28+1.52+%2B+13.3+%29+%2F+57+=+.26+

(1) +14.82+=+.26%2A57+

(1) +14.82+=+14.82+

Answer:

85

Step-by-step explanation:

The sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle.

As you can see in the attached image we can find the measure of the interior angle using the straight line and find the value of missing angle

25 + 60 = 85

Using the fundamental counting theorem, we have that:

The fundamental counting principle states that if there are p ways to do a thing, and q ways to do another thing, and these two things are independent, there are ways to do both things.

For the area code:

Thus:

[tex]8 \times 9 \times 9 = 648[/tex]

648 different area codes are possible with this rule.

For the number of 10-digit phone numbers:

Then

[tex]648 \times 10^7 = 6,480,000,000 [/tex]

There are 6,480,000,000 possible 10-digit phone numbers.

The amount of possible phone numbers is greater than 400,000,000, thus, there are enough possible phone numbers.

Answer:

Social Security: $201.50, Medicare: $47.13

Step-by-step explanation:

divide 78,000 by 24(semimonthly) - $78000/24 = $3250(gross semimonthly basis)

multiply 3250 by .062(social security) - 3250 x .062 = $201.50

multiply 3250 by 0.0145(medicare) - 3250 x 0.0145 = $47.13
