Answer:
840mi. - 12 hrs
x - 3 hrs
This is a simple cross multiplying problem.
840 _ 12
x -- 3 ⇒12x=3(840) ⇒ 4x=280 ⇒ x=70 miles
:D
Step-by-step explanation:
The ratio of book price to number of pages for the ordered pairs a, b , and c are:
- <em>A = 0.05</em>
- <em>B = 0.05</em>
- <em>C = 0.043</em>
The ratio of book price to number of pages can be evaluated for each ordered pairs as follows;
Therefore, ratio of book price to number of pages for the ordered pairs a, b , and c are:
a = 0.05
b = 0.05
c = 0.043

C. s is your answer.
The sum of 2 angles on a straight line (supplementary angles) is 180°. Vertical angles (opposites where a line intersects) are equal.
The upper left and lower right angles where p crosses the other lines (q, r, t) are 105°.
180 - 105 = 75°
So the upper right and lower left angles are 75°. The lower left angle where p intersects s is 85°, so it is not parallel to the others.

Answer:
least common multiple (LCM) of 5 and 12 is 60
Step-by-step explanation:
I am not sure what exactly you mean.
do you mean the complete square of an expression or
term ?
if so, then by multiplying this term by itself, and that means in general, every part is multiplied by every part and the part results are added considering the signs involved.
e.g.
squaring a+b
(a+b)(a+b) = a×a + a×b + b×a + b×b = a² + 2ab + b²
remember that multiplication and addition are commutative (you can flip the right and left sides with each other and still get the same result : a+b = b+a, a×b = b×a).
squaring a-b
(a-b)(a-b) = a×a + a×-b + -b×a + -b×-b = a² - 2ab + b²
remember that
+×- = -×+ = -
-×- = +
+×+ = +
a more complex example ?
squaring a-b+c
(a-b+c)(a-b+c) =
= a×a + a×-b + a×c + -b×a + -b×-b + -b×c + c×a + c×-b + c×c =
= a² - 2ab - 2bc + 2ac + b² + c²
