Answer:
I think 2+-1x+9y
Step-by-step explanation:
Just add the numbers that have the same variables
1.) a>10
2.) a<3.5
How I got it: 1.) Subtract 3 from both sides, leaving -2a<10.
2.) Divide by -2 from both sides, remember to flip the inequality sign when dealing with negatives. This leaves you with a>10.
For number 2.) I divided both sides by 5, leaving a<3.5, though this answer may be wrong.
Step-by-step explanation:
a. true

b. false
property: communitive
c. true

d. false
property: multiplication property of zero
Answer:
Step-by-step explanation:
If I read this correctly...
5 1/5^3= 5.20^3=140.608
5(5)^3=625
If this isn't the correct problems, sorry. it was kind of hard to decipher the last one.
U . v = |u| . |v| cos 60 = 10 * 8 * 0.5 = 40 This is called the scalar (or dot) product.
