Answer:
x=13
Step-by-step explanation:
Switch sides:
2x−9=17
Add 9 to both sides:
2x−9+9=17+9
Simplify
2x=26
Divide both sides by 2:
2x/2 =26/2
Simplify to get the result.
x=13
Answer:
it is the equation which you have to solve.
75 because 7+77=84 and 84-9=75
Answer:
The plumber worked for 1.5 hours
Step-by-step explanation:
y = 130 + 56x
Substitute 214 for y in the equation
214 = 130 + 56x
-130 -130 Subtract 130 from both sides
84 = 56x Divide both sides by 56
1.5 = x
Answer:
Concept: Geometric Identities
- We want BC
- We will use geometric identities to get our value
- We have BA and AC and angle !A
- Hence arccos(89)= 21/x
- Hence X=25 km B
