You divide 2.5 to both the miles and hours to get 1 hour and the miles remain.
The answer is 54 miles
Answer:
m∠2= 180-30=150
m∠3= 30
m∠4=30
m∠5=150
m∠6=150
m∠7=30
Step-by-step explanation:
since these are angles of parallel lines cut by a transversal the theorems of vertical, corresponding, supplementary, and complementary angles apply.
Answer:
Step-by-step explanation:
The area for a rectangle is A = LW. We know the area and we also know the length. We are solving for the width.
and
Siince the width is given as the square root of x, and the square root of x is equal to 16, then the width is 16. Now to find the value of x from the last statement in our equation. If
and we want to solve for x, we will square both sides, since squaring undoes a square root. Since this is an equation, we have to square both sides.
256 = x
Okay, let's use x for the 24 page packages and y for the 30 page packages:
x + y = 9
x = -y + 9
Now here's the second equation:
24x+30y = 258
We can input y into our second equation:
24(-y + 9) + 30y = 258
-24y + 216 + 30y = 258
6y = 42
y = 7
9 - 7 = 2, so:
