Each student sells 9 balloons because 162 balloons divided by 6 groups of students is 27, and 27 divided by 3 students is 9 balloons.
Answer:
- y = 1.5x
- y = 15 when x = 10
Step-by-step explanation:
A direct variation equation is of the form ...
y = kx
for some constant k. We can arbitrarily choose k=1.5, so our equation is ...
y = 1.5x
For x=10, the value of y is ...
y = 1.5·10 = 15
Answer:
x = 7
Step-by-step explanation:
The angle adjacent to the 70 degree angle is also 70 degrees. We assume that there are four 90-degree angles in the center of the figure. Thus, 8x - 36 + 70 + 90 = 180 (the sum of the interior angles is 180 degrees).
Solving 8x - 36 + 70 + 90 = 180 for x:
8x - 36 = 20, or 8x = 56.
Dividing both sides by 8 yields x = 7.
