Answer:

16

Step-by-step explanation:

Use PEMDAS to find the solution.

First, you solve what in the Parenthesis and evaluate the power aka the exponent.

---> 8 + 16/2

Next, you divide and multiply. In this case, we only divide the 16 by 2.

---> 8 + 8

Finally, you add or subtract. In this case, we add.  

---> 8+8 = 16

Write a real world problem for the following equation:<br> 80-3x=53
Afina-wow [57]

Answer:

x=9

Step-by-step explanation:

Step 1: Simplify by both sides of the equation.

80-3x=53

80+-3x=53

-3x+80=53

Step 2: Subtract 80 from both sides.

-3x+80-80=53-80

-3x=-27

Step 3: Divide by both sides by 3.

-3x/-3 = -27/-3

x=9

I don’t understand stand this question someone please help me with work shown
djyliett [7]

Answer:

60°

please look into the solution down here.

Step-by-step explanation:

since BD bisects it, then the angles should be bisected symmetrically, or in other words, ANGLE ABD = angle DBC,

hence,

4x = 2x +30

2x = 30

x = 15

therefore, angle DBC = 2x + 30 = 2(15) + 30 = 60°.
