Answer:
-1
Step-by-step explanation:
(8 + -9)(9 + -8)
A negative times a positive is a negative.
8 + -9
+- = -
8 - 9
8 - 9 = -1
(-1)(9 + -8)
9 + -8
+- = -
9 - 8
9 - 8 = 1
(-1)(1)
Now, we multiply
Remember, a negative times a positive equals a negative.
-1 * 1 = -1
Our answer is -1
A quotient is the result of a division.
Let the unknown number be x.
We translate the problem into an equation, piece by piece.
<span>"quotient of a number and seven" ----> x/7
</span>
<span>"12 less than the quotient of a number and seven" ----> x/7 - 12
The word "is" means "="
x/7 - 12 =
All the above is -2, so it equals -2.
x/7 - 12 = -2

First, add 12 to both sides and simplify.

Next, multiply both sides by 7.

Answer: The number is 70.
Step-by-step explanation:
<em>Vamsi is X years old</em>
Vamsi = X
<em>his brother is 3 years elder to him</em>
Brother = X + 3
<em>his uncle is 4 times his age</em>
Uncle = 4X
<em>his aunt is 5 years younger than his uncle</em>
Aunt = Uncle - 5
<em>what will be the age of his uncle 6 years from now</em>
= 4X + 6
<em>what are the ages of vamis brother, uncle and aunt?</em>
Assume Vamis = 15 years
Brother = X + 3 = 15 + 3 = 18
Uncle = 4X = 4 * 15 = 60
Aunt = Uncle - 5 = 60 - 5 = 55
<em>what will be the age of his uncle 6 years from now</em>
Uncle = 4X + 6 = 60 + 6 = 66
Answer:
<h2>330 different possible selections are there.</h2>
Step-by-step explanation:
There is a total of 11 cut flowers.
Jeanine Baker has to choose 7 flowers among the 11 flowers.
The formula for choosing r numbers from n numbers is defined by
, n > r.
From 11 flowers 7 flowers can be chosen in
= 330 ways.
There are 330 possible ways to choose 7 flowers from 11 flowers.
Use the trigonometry triangles SOH CAH TOA
Sin= opposite/hypotenuse
Opposite= opposite the angle
Hypotenuse is the longest side
