Answer:
angle1 : angle 2:
72 108
Step-by-step explanation:
Supplementary angles add to 180
angle1 : angle 2:
2 3
Multiply each term by x
2x 3x
The total is 180
2x+3x= 180
5x= 180
Divide by 5
5x/5 =180/5
x =36
angle1 : angle 2:
2*36 3*36
72 108
Answer:
Option (d) is correct.
Step-by-step explanation:
The equations are :
-x-2y=-4 .....(1)
3x+y=12 ....(2)
Equation (1) can be rewritten as follow :
-x = -4+2y
x = 4-2y .....(3)
So, to solve the above systems of equations, we must substitute the value of x from equation (3) in equation (2). Hence, the correct option is (D).
Answer:
25 4-point questions and 75 2-point questions
Step-by-step explanation:
Let x = no. of 4-point questions
Then 3x = no. of 2-point questions
So, x + 3x = 100
4x = 100
x = 25 = no. of 4-point questions
and 3x = 3(25) = 75 = no. of 2-point questions
Answer:
(-1,5)
Step-by-step explanation:
To find this, you have to add both "x" coordinates, then divide them by two.
Same thing goes for the "y" coordinates, add them, then divide them by two.
x-coordinates ---> 2+(-4)= -2
y-coordinates ---> 1+9= 10
-2÷2= -1
10÷2= 5
That gives you, (-1,5).
