X represents the number of sodas
y represents the number of hot dogs
142 = x + y
x = 38 + y
Substitute x in the first equation
142 = 38 + y +y
142 - 38 = 2y
104/2 = 2y/2
y =52
x = 38 + 52
x = 90
Answer: H=2 i just took the test
Step-by-step explanation:
Answer:
60 degrees
Step-by-step explanation:
angle y is vertically opposite to angle a, (we can call it.)
angle x is supplementary to the other angle inside the triangle, which we can call angle b.
so, angle a is 60 degrees, as vertically opposite angles are equal
angle b is 60 degrees as supplementary angles = 180
based of the sum of angles in a triangle is 180 theorem;
60+60+unknown= 180
so unknown is 60 degrees
Y=1/4x + 3/4
Multiply by 4 each sides
4y= x + 3
Subtract x from both sides
-x + 4y = 3
Multiply both sides
X- 4y= -3
4x (2x-3) (x+2) would be your answer.
