Answer:
BC = 23
Step-by-step explanation:
Since ∠ A = ∠ C then the triangle is isosceles with AB = BC, that is
3x + 14 = x + 20 ( subtract x from both sides )
2x + 14 = 20 ( subtract 14 from both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Thus
BC = 3x + 14 = 3(3) + 14 = 9 + 14 = 23
There are 100 centimeters in one meter
therefore .1 meters = 10 centimeters
.01 meters = 1 centimeter
to convert form centimeters to meters you will move the decimal to the left 2 times starting from the far most right digit.
No idea I don't know the answer
Answer:
×=17/4
Step-by-step explanation:
The equation 2x+ 4=-6x+38
First of all you collect like terms by moving the number -6x over to the left hand side which then becomes +6x as it crosses the equal to sign, likewise you move +4 over to the right hand side which then becomes -4. The equation is now 2x+6x=38-4, which when solved gives 8x=34. X is then made subject of formula by dividing both sides by 8 therefore x=34/8 which when reduced to the lowest term is 17/4
