Answer:
22a + 12b
Step-by-step explanation:
First, you should combine like terms. Like terms are when numbers have the same variable, such as the variable 'a'.
26a and -4a both have 'a' as their variable. To combine them, add -4a to 26a. You should get 22a as your final result.
The other two numbers in this equation that share a common variable are 2b and 10b. To combine these, all you have to do is add them together. After adding these two, you should get 12b.
After combining all like terms, there is none left, meaning you can't combine 22a and 12b since they don't share the same variable.
Use PEMDAS.
17-(6×10÷2)+12
6×10=60 divide by 2 to get 30
now: 17-30+12
17-30=-13
-13+12=-1
A vector in its standard form is given by:
v = lvl * (cos (theta) i + sin (theta) j)
If we multiply the vector by a scalar -pi we have:
v = -pi * lvl * (cos (theta) i + sin (theta) j)
We observe the following changes:
The magnitude of the vector is greater.
The vector changes direction.
Answer:
A. The vector will change direction and increase in magnitude.
Answer:
350 adult tickets were sold
Step-by-step explanation:
Let x represent the number of adult tickets sold.
Since there were 60 fewer student tickets sold than adult tickets, the number of student tickets sold can be represented by x - 60
Create an equation that sets up these terms equal to 640, then solve for x:
(x) + (x - 60) = 640
2x - 60 = 640
2x = 700
x = 350
So, 350 adult tickets were sold
(40+41+41+45+48+48+49+49+49+40)/10 = 460/10 = 46
mean = 46
