Equality Properties

Step-by-step explanation:

<u>Step 1: Define Equation</u>

4x - 8 = 16

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Add 8 to both sides:                    4x = 24
  2. Divide 4 on both sides:               x = 6

<u>Step 3: Check</u>

<em>Plug in x into the original equation to verify it's a solution.</em>

  1. Substitute in <em>x</em>:                   4(6) - 8 = 16
  2. Multiply:                              24 - 8 = 16
  3. Subtract:                             16 = 16

Here we see that 16 does indeed equal 16.

∴ x = 6 is the solution to the equation.

How to turn 69% into a ratio
tia_tia [17]
Since percents are out of 100 (69/100), you can change them to a ratio which in this case would be 69:100 because it can't be simplified.

Given that ABCD is a parallelogram, what must be proven to prove that the diagonals bisect each other?
Yuliya22 [10]

Answer:

We have to prove  Δ ABO ≅ Δ CDO or,  Δ DAO ≅ Δ BCO.

Step-by-step explanation:

Let us assume that ABCD is a parallelogram having diagonals AC and BD.

We have to prove that in a parallelogram the diagonals bisect each other.

Assume that the diagonals of ABCD i.e. AC and BD intersect at point O.

Therefore, to prove that the diagonals AC and BD bisect each other, we have to first prove that Δ ABO and Δ CDO are congruent or Δ DAO and Δ  BCO are congruent.

In symbol, we have to prove  Δ ABO ≅ Δ CDO or,  Δ DAO ≅ Δ BCO. (Answer)

SIZIF [17.4K]

Answer:

i think the answer is D

Step-by-step explanation:

87 degrees minus 10 degrees would give you 77 (which is the lowest temperature). then 77 degrees plus 17 degrees is 94 degrees. the difference between the highest temp and lowest (94-77) would be 17.
