Answer:
C)
Step-by-step explanation:
Because -8.2+(-4.1)=-8.2-4.1=-12.3.
Answer:
y = -5
o = 35 degrees
Step-by-step explanation:
If you replace y with -5, the statement 7y = 4y - 15 is correct. You get -35 = -35. Hope this helped!
Let's solve your equation step-by-step.
(−
1
/5
)(c)+2+c=
1
/5 (10c−20)
Step 1: Simplify both sides of the equation.
(−
1
/5
)(c)+2+c=
1
/5
(10c−20)
(−

c+2+c=2c+−4
(

/5
c+c)+(2)=2c−4 (Combine Like Terms)
4
/5
c+2=2c−4
4
/5
c+2=2c−4
Step 2: Subtract 2c from both sides.
4/5
c+2−2c=2c−4−2c
−6
/5
c+2=−4
Step 3: Subtract 2 from both sides.

c=−6
Step 4: Multiply both sides by 5/(-6).

Answer:
c=5
0.2 I believe would be the correct conversion. if not please feel free to correct me.
Answer with Step-by-step explanation:
We are given that:
tanA = 0.45
tanA= 
= 
⇒ =0.45
⇒ 
=
⇒ =
⇒ AC= 20
Hence, by pythagoras theorem
AB²=AC²+BC²
AB²=20²+9²
AB²=481
⇒ AB=21.9 units
Hence, the approximate length of AB is:
22 units
