Answer:
C. 5
Step-by-step explanation:
3x – 7 > – 1
Add 7 to each side
3x – 7+7 > – 1+7
3x> 6
Divide each side by 3
3x/3 >6/3
x >2
X must be greater than 2
Answer:
a = 50°, b = 130°, c = 20°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles in the right triangle
a + 40° + 90° = 180°
a + 130° = 180° ( subtract 130° from both sides )
a = 50°
a and b are adjacent angles and sum to 180° , so
a + b = 180°
50° + b = 180° ( subtract 50° from both sides )
b = 130°
Then sum the angles in the top triangle, that is
30° + 130° + c = 180°
160° + c = 180° ( subtract 160° from both sides )
c = 20°
Answer: 150
Step-by-step explanation:
30% = 0.3
100-30=70
70% = 0.7
0.7 X 500 = 350
500-350 = 150
Since 0 < y < 1.5, hence the coordinate (1,1) is a solution
<h3>A solution to the system of inequality</h3>
Given the following inequality expression
y>0
y< 2.5x - 1
Wee are to check if (1, 1) is a solution to the systen of equation
If x = 1
y < 2.5(1) - 1
Y < 2.5 - 1
y < 1.5
Since 0 < y < 1.5, hence the coordinate (1,1) is a solution
