To solve this you do 25-7=18 and do 18÷6=3, so my number is 3. To check if this is correct you do 3×6=18 and 18+7=25

If tan2A=cot(A+60), find the value of A, where 2A is an acute angle

jeka57 [31]

Answer:

Here the answer is 10=a

Step-by-step explanation:

= Tan 2A = cot(A+60°)

= cot(90-2A) = cot (A+60°)

= 90°-2A = A+60°

= 90°-60° =A+2A

= 30 = 3A

= 30\3 = A

= 10 = A

Answer:

8b- 13 6/7

Step-by-step explanation:

A product of 8 and b just means 8 x b or 8b.

13 6/7 less than that product means subtraction.

Therefore, it would be 8b - $13\frac{6}{7}$

What is the solution to the system of linear equations? y=4x and y-4x=0

musickatia [10]

Answer:

y = 4x; there are an infinite number of solutions

Step-by-step explanation:

Both equations describe the same relation between x and y. The system is "dependent", so has an infinite number of solutions. For any value of x, the solution is ...

(x, y) = (x, 4x)

Choose the best description for the real number 35

Natalija [7]

Answer:

A) Irrational, because it is not a terminating or repeating decimal.

Step-by-step explanation:

Every time a square root results in a decimal, it will always never end, and never repeat. The square root of 35 qualifies for both of these qualities, therefore, making the answer (A). Hope this helps!
