Answer:
4/5
Step-by-step explanation:
Subtracting 7 from both sides you get 5x=4 dividing by 5 you get 4/5=x
Answer:
1/3 of an hour
Step-by-step explanation:
Because we already have the same common denominator, subtract the numerators to solve:
Isa has 1/3 of an hour left to play video games (20 minutes).
Answer:
Step-by-step explanation:
The general equation for a parabola in vertex form is the following:
Where () is the parabola's vertex and (a) is the stretch and compression factor. As one can see in the given graph, the parabola has a vertex at (0, 1), moreover, it passes through the point (1, 3). Substitute these points into the equation for the parabole, and simplify,
Vertex: (0, 1)
A point on the parabola: (1, 3)
Inverse operations,
Substitute back into the original expression:
Simplify to put in standard form:
Let other 2 angles be d
44 + 2d = 180°
(sum of triangle)
2d = 180 -44
2d = 136
d = 136/2
d = 68
x = 68 + 44 (exterior angle is equal to sum of interior opposite angles)
x = 112°
l
2. part
let the other angles be d
3d = 180° (sum of angles of triangle)
d = 60°
x = 60 + 60
x = 120°
