x=3
Step-by-step explanation:
Answer: b=5
Step-by-step explanation:
Multiply all terms by b and cancel:
3b/5+2=1b
3/5b+2=b(Simplify both sides of the equation)
3/5b+2−b=b−b(Subtract b from both sides)
−2/5b+2=0
−2/5b+2−2=0−2(Subtract 2 from both sides)
−2/5b=−2
(5−2)*(−25b)=(5−2)*(−2)(Multiply both sides by 5/(-2))
b=5
Check answers. (Plug them in to make sure they work.)
b=5 (Works in the original equation)
Answer:
b=5

Answer:
1. 51°
2. 40°
3. 65°
4. 60°
Step-by-step explanation:
The sum of the angles in a triangle is 180°. We can use the angles given to find the missing angle.
1. 51°
42+87+x=180
129+x=180
x=51
-------------------------------------------------------------------------------
2. 40°
110+30+x=180
140+x=180
x=40
-------------------------------------------------------------------------------
3. 65°
20+95+x=180
115+x=180
x=65
-------------------------------------------------------------------------------
4. 60°
60+60+x=180
120+x=180
x=60
Answer:
17: A,C,B 18: C,A,B 19: A,C,B 20:A,C,B
Step-by-step explanation:
Slope(rate of change) can be found by dividing the change in y over the change in x. For example, #17 table, the change in y is (1-0)=1 and the change in x is (6-3)=3. Now, divide the to to get 1/3. Once you have all the rates of change you can list them in order.
