Answer:
11/1 or 11
Step-by-step explanation:
hope this helps
Let x be the first angle
y be the second angle
z be the third angle.
for the second angle, complementary angles are angles sum are 90 degrees
y = 2 ( 90 - x )
y = 180 - 2x
2x + y = 180
for the third angle, supplementary angles are angles sum are 180 degrees
z = 0.5( 180 - x )
z = 90 - 0.5x
0.5x + z = 90
then the sum of a triangle is 180
x + y + z = 180
so x = 60
y = 60
z = 60
Answer:
The correct options are;
1) "Greater/Less than or equal to" means the circle on the number will be SOLID
2)"Greater/Less than" means the circle on the number will be open
3) If It is "greater than", the line will be colored to the RIGHT of the number & if it is "less than", the line will be colored to the LEFT of the number line
Step-by-step explanation:
When a linear inequality is graphed on a number line, and the value of the inequality is "less than" or "greater than" the limit displayed on the number line, the limit of the inequality is indicated by an open
When the the limiting value of the inequality is specified as "less than or equal to" or "greater than or equal to" the value displayed on the number line as a SOLID circle.
The region where the inequality is valued on the number line is the colored region.
Hi!
You need to multiply them. So 4x1=4 and 9x11=99
Answer : 4/99
-2x + y = -3.....multiply by -2
-x + 2y = 3
-----------------
4x - 2y = 6 (result of multiplying by -2)
-x + 2y = 3
----------------add
3x = 9
x = 9/3
x = 3
-2x + y = -3
-2(3) + y = -3
-6 + y = -3
y = -3 + 6
y = 3
solution is (3,3)
