(10n-5)/(5)= 2n-1
just divide
10/5 = 2 and -5/5 =-1
and you get the answer
2n-1= 2n-1
Answer:
The answer is -4x^2
Step-by-step explanation:
-3x^2 - 5x^2 + 4x^2
= -3x^2 + -5x^2 + 4x^2
Combine like terms:
-3x^2 + -5x^2 + 4x^2
(-3x^2 + -5x^2 + 4x^2)
= -4x^2
Answer:
a. $25.20
b. $445.20
Step-by-step explanation:
$420*(6%/100%) = $25.20
$420+$25.20 = $445.20
X = 75% * y
Where 'x' is the single tennis court width, and 'y' is the doubles tennis court width.
Plug in what we know:
27 = 75% * y
75% = 0.75
27 = 0.75 * y
27 = 0.75y
Divide 0.75 to both sides:
y = 36
So the doubles court is 36 feet wide.
Answer:
2 positive * 1 negative = negative
2 negative * 1 positive = positive
Step-by-step explanation:
one positive and 2 negative
(+ * -) * - =
positive times negative = negative * negative = positive
(+ * -) * - = +
now if we change the order by putting parenthesis
+ *( - * -)
negative time negative = positive
+ * (+) = positive
the result is positive
The result does not change because of where we put the parentheses.
- * + * + =
negative times positive = negative
negative * positive= negative
- * + * + = negative
The order does not matter
