-5+1/5a=4
solution again.

Answers

Answer 1

Answer:

Isolate the a. Note the equal sign. What you do to one side, you do to the other.

Add 5 to both sides

-5 (+5) + 1/5a = 4 (+5)

1/5a = 9

Isolate the a. Multiply 5 to both sides

(5)(1/5)a = 9(5)

a = 9 x 5

a = 45

45 is your answer for a.

hope this helps

Explain why 17 tens. and 1 hundred 7 tens have the same value

Answers

we know that

$1\ tens=10 \n1\ hundred=100$

1) the expression $17\ tens$ is equal in numbers to

$17\ tens=17*10=170$

2) the expression $1\ hundred\ 7\ tens$ is equal in numbers to

$1\ hundred\ 7\ tens=1*100+7*10=100+70=170$

therefore

$17\ tens$ and $1\ hundred\ 7\ tens$ have the same value

because 1 hundred and 7 tens equal 170
and 17x10 equals 170

Answer:

276°

Step-by-step explanation:

In the figure attached, circle D is shown.

arc BA + arc AC + arc CB = 360°

(7n + 12) + (13n - 16) + 6n = 360

26n - 4 = 360

n = (360 + 4)/26 = 14°

arc BAC = arc BA + arc AC

arc BAC = (7n + 12) + (13n - 16)

arc BAC = 20n - 4

arc BAC = 20(14) - 4 = 276°

Answer:

The answer is 276 degrees. I checked on Khan Academy. The reason 84 degrees is NOT the answer is because that would be the minor arc, not the major arc.
