The answer is 90 a triangle is 180 degrees a we know that A is a right angle is 90 and B is 45 so that leaves us with 45 degrees on C. But since we are measuring BC we add them up and that equals 90

T-1 —— = 12. What is t 2 7+a -4= ——. What is a 5

Nana76 [90]

For 3.) you would multiply both sides by 2

t-1=24

Then add

t=22

For 4.) multiply by 5

-20= 7+a

Then subtract

-27=a Hope this helps!

3t - 7 = 5t, then 6t= ?

netineya [11]

Answer:

t = -5/2
-21

Step-by-step explanation:

3t - 7 = 5t

~Subtract 3t to both sides

-7 = 2t

~Divide 2 to both sides

-7/2 = t

~Find 6t with what we found for t

6(-7/2)

-21

If 9x is an odd integer, represent the next odd integer as the algebraic expression in x.

Luba_88 [7]

Any odd integer can be expressed as 2n+1, for some integer n.

The next odd integer, after 2n+1, is 2n+1+2=2n+3

thus 9x=2n+1, means that 9x-1=2n, so n=(9x-1)/2

the next odd number after 2n+1 is 2n+3= 2* (9x-1)/2+3=9x-1+3=9x+2

Remark : this result could also have been found directly.

Answer: 9x+2
