Answer:
2x + 12 = 64
x = 26 (mark brain if this helps and is correct)
Step-by-step explanation:
to solve equations with one missing variable we must use the order of operations of equality
step 1: use the subtraction property of equality meaning subtract each side of the equation
ex: 2x + 12 - 12 = 64 - 12 (2x = 52)
step 2: use the division property of equality meaning divide each side of the equation by 2
ex: 2x/2 = 52/2 (x = 26)
step 3: check your answer by putting 26 as x because that is our answer
2(26) + 12 = 64 (multiply 2 * 26)
52 + 12 = 64 (add 52 + 12)
64 = 64 (if both sides of the equation are the same number like 64 = 64 then your answer is true meaning that x is equal to 26)
The equation is y=(-1/2)x +2
Answer: 1649
Step-by-step explanation:
2/3=3r
divide both sides by 3
remember that dividng by 3 is the same as multiplyint by 1/3
2/3 times 1/3=2/9=r
r=2/9
Answer
Find the approximate value of sin C .
To proof
By using the trignometric identity

Now as given in the diagram

as in the diagram
AB = 5 units
BC = 13.93 units
Now put it in the identity

solving
sinC = 0.36° (approx)
Option (D) is correct
Hence proved
