Since Charles runs a 1/4 mile in 10 minutes, and 1/4 goes into 1 1/2 6 times, the answer is 10*6, which is 60.
Answer:
X=150
Solution: using geometry rules, the concept that all angles in a triangle equal to 180 degrees, you get x=150

Answer:
Step-by-step explanation:
If the second angle's measure is based on the first angle's measure, and the third angle's measure is also based on the first angle's measure, then the first angle is the main angle. We will call that x.
1st angle: x
2nd angle: x + 20%
3rd angle: x - 20%
By the Triangle Angle-Sum Theorem, all those angles will add up to 180, so:
x + (x + 20%) + (x - 20%) = 180 and
3x = 180 so
x = 60. That means that
2nd angle: 60 + (.2*60) which is
60 + 12 = 72 and
3rd angle: 60 - (.2*60) which is
60 - 12 = 48. Let's check those angles. If
∠1 = 60
∠2 = 72
∠3 = 48,
then ∠1 + ∠2 + ∠3 = 180 and
60 + 72 + 48 does in fact equal 180, so you're done!
Answer:
12x + 40y
Step-by-step explanation:
4(3x+10y)
multiply the outer number (4) with all the terms inside the parentheses
4 X 3x + 4 X 10y
12x + 40y
