Solving (48):
To solve for Y, we have:
--- sum of angles in a triangle
This gives
Where
-- angle on a straight line
Solve for X
So, we have:
Answer:
four twelfths
Step-by-step explanation:
multiply by 2/2 to get 4/12
Answer:
1/7.
Step-by-step explanation:
To solve this, we can simply use an equation to solve for the slope using two points:
We can substitute our points giving us:
The slope of the graph is 1/7!
Never true. Vertical angles are equal to each other, not adjacent to each other.
Answer:
800. Here's why:
Step-by-step explanation:
This indicats that 440 students make up 55% of the 6th grade population. We can write this as
55/440.
We also know that 'x' total students make up 100% of the 6th-grade population, so we can write this as
100/x.
55/440 must be equal to 100/x. When cross multiplied, it becomes 50x=44000. If we divided each side by 50, we'll find that x=880. Therefore, there are 800 6th graders
