Since 0.6=6/10 the answer is c
$1.45
1.50 times .05= 0.075
the sales tax was 0.075 cents, so if you subtract that from $1.50, you get the price before sales tax
Answer:
Remember what a right triangle is. A right triangle is a triangle that has one right (90 degree) angle.
Recall the Pythagorean Theorem. The Pythagorean Theorem tells us that for any right triangle with sides of length a and b, and hypotenuse of length c, a2 + b2 ...
Look at your triangle, and label the sides "a," "b," and "c". Remember that the longest side of the triangle is called the hypotenuse.
Step-by-step explanation:
To solve this you first need to turn your mixed numbers into improper fractions. to do this for
you multiply the denominator (5) by the whole number (9) to get 45 and then add that to the numerator (4) to get your new fraction
.
You repeat this process with
to get
.
Now that you have two fractions you can multiply by the opposite reciprocal. To do this you flip the second fraction and change the division sign to a multiplication sign like so
Then, you just multiply the fractions by multiplying the numerators to get 98 and multiplying the denominators to get 35.
Now, to simplify
you first divide both the numerator and denominator by 7 to get
.
Finally, you can take 10 out of the numerator to make

=2(</span>y^2 + 6y- 27)<span>
=2 (y - 3)(y+9)</span>
