(X+3)(2x-1)
=2x square -x + 6x - 3
=2x square +5x -3
Answer:
x = 30
Step-by-step explanation:
The angle in the bottom right is 120
Call is y
y+60 = 180
y = 180-60
y =120
Opposite angles in a parallelogram are equal so the upper left angle is 120
Call the 3x +z = 120
We also know that 2x+90 +z = 180 since it forms a straight line
Subtract 90 from each side
2x+z = 90
Using 3x+z = 120 and 2x+z =90 and subtracting the second equation
3x+z = 120
-2x-z =-90
------------------
x = 30
Answer:
23/90
Step-by-step explanation:
Create a variable called "x" with a value of 0.2555 repeating.
10x would be equal to 2.555 repeating.
Calculate 10x - x using these numbers; 2.555 repeating minus 0.2555 repeating is 2.3 (the repeating fives subtract and cancel out). 2.3 is equal to 9x, so to find x, we write the fraction 2.3/9. To get rid of the decimal in the numerator, we multiply both the numerator and the denominator by 10: this gives 23/90. 23 is a prime number, so we know this fraction cannot be simplified further.
Answer:
t > 3
Step-by-step explanation:
3(2t - 6) > -2(3t - 9)
Distribute
6t - 18 > -6t + 18
+6t +6t
12t - 18 > 18
+18 +18
12t > 36
divide both sides by 12
t > 3
hope this helps!!!
