Answer:
|-3| = 3 and -|-4| = -4
Step-by-step explanation:
The absolute value function changes the sign to positive, if it isn't already. The usual rules of arithmetic and logic apply to these statements.
|-3| = 3 (true) and -|-4| = -4 (true) ⇒ this statement is true
|-3| = 3 (true) and |-4| = -4 (false) ⇒ this statement is false
-|3| = 3 (false) and |4| = 4 (true) ⇒ this statement is false
|-3| = 3 (true) and -|4| = 4 (false) ⇒ this statement is false

A compound "and" statement is only true if <u>all</u> of the parts of it are true.
Answer:
He needs 16 ounces of raisins and 8 ounces of nuts
Step-by-step explanation:
Let
x -----> the number of ounces of raisins
y -----> the number of ounces of nuts
we know that
x+y=24 -----> equation A
x=2y -----> equation B
Solve the system by substitution
Substitute equation B in equation A and solve for y
(2y)+y=24
3y=24
y=8 ounces of nuts
Find the value of x
x=2(8)=16 ounces of raisins
therefore
He needs 16 ounces of raisins and 8 ounces of nuts
Answer:
To be Honest I kinda do know but I can solve the equation for you if that helps
Step-by-step explanation:
5x+15y-6 is the answer
first you will add all of them and then distribute
Remove parentheses
=3x-18+15y+6+2x+6
Group like terms
=3x+2x+15y-18+6+6
Add similar elements
=5x+15y-18+6+6
Finally Add/Subtract the numbers
=5x+15y-6
Answer:
13 cents, 17 cents, Brand A
Step-by-step explanation:
The unit price is the price of a single pencil. You can find that by dividing the total price by the number of pencils.
Brand A= $2.36/18= $0.13
Band B= $4.09/24= $0.17
0.13 < 0.17
Brand A is cheaper because the price per pencil is less.
