Steps to solve:
2x - 7 > 3
~Add 7 to both sides
2x > 10
~Divide 2 to both sides
x > 5
Steps to solve:
4 - x <= -4
~Subtract 4 to both sides
-x <= -8
~Divide -1 to both sides
x >= 8
Best of Luck!
3 x 5/7 + 2 x 6/7
15/7 + 12/7 = 27/7 or 3.85714286
Answer:
(a)
Step-by-step explanation:
using the following
The sum of the 3 angles in a triangle = 180°
The sum of the angles on a straight angle = 180°
To find x subtract the sum of the 2 given angles in the triangle from 180
x = 180 - (56 + 38) = 180 - 94 = 86 ( sum of angles in a triangle )
To find z, subtract x from 180
z = 180 - 86 = 94 ( angles on a straight angle )
To find y subtract the sum of the 2 angles from 180
y = 180 - (94 + 19) = 180 - 113 = 67
x = 86, y = 67 and z = 94
1) Turn -2 1/4 to decimal:
x -3 = -2.25
2) add three to both side to cancel out for x:
x= .75
Answer: x = .75 OR 3/4
