Answer:
y = 15
Step-by-step explanation:
In a parallelogram, opposite lengths are equal.
So it means that the length (5y - 20) is equal to (2y + 25).
Now that there is only one variable in the equation, we can solve for the variable.
5y - 20 = 2y + 25
5y - 2y = 25 + 20
3y = 35
y = 15
Answer:
Step-by-step explanation:
Write 124 in scientific notation.
Then, in scientific notation, 124 is written as 1.24 × 102. Actually, converting between "regular" notation and scientific notation is even simpler than I just showed, because all you really need to do is count decimal places.
Answer: 4.35 - 5.5 = -1.15 ≈ - (23÷20)
Step-by-step explanation:
4.35 - 5.5= -1.15
The equivalent equation to 4.35 - 5.5 will be,
-1.15 ≈ - (23÷20)
