Answer:
x = -7/2
Step-by-step explanation:
½(4x - 8) = 6x + 10
simplify
2x - 4 = 6x + 10
subtract 6x from both sides
-4x - 4 = 10
add 4 to both sides
-4x = 14
divide both sides with -4
x = -14/4
simplify
x = -7/2
Answer:
77 weeks
Step-by-step explanation:
Let the number of weeks be represented as x
The equation for the above question is given as:
146 + 2(x) = 300 pieces
146 + 2x = 300
2x = 300 - 146
2x = 154
x = 154/2
x = 77

Answer:
∠ ADB = 19°
Step-by-step explanation:
Consecutive angles in a parallelogram are supplementary, sum to 180° , so
∠ CDA = 180° - ∠ DAB = 180° - 138° = 42°
Then
∠ ADB + ∠ CDB = 42° , that is
∠ ADB + 23° = 42° ( subtract 23° from both sides )
∠ ADB = 19°
Let the number be x, the square of x is x^2, then
The product of the square of x and 5 is 5x^2.
