Steps:
1st write out equation
Second write the conjugant and multiply it.
After multiplying you should get,
now after simplifying you should get
A number is divisible by 4 when the last two digits is divisible by 4.
The answer will be B; this is because the cost of each notebook is equivalent to 1.6, or is less than or equal to $56 as we are currently unsure of the value of n (number of notebooks) which means it may cost exactly $56 or less than that as she only has $56 to buy the notebooks to donate to her school
Answer:
a^2 + 3b - 2a^2 = 3a^2 +3b -4a^2
Step-by-step explanation:
-a^2 + 3b + 2a^2 = 3a^2 +4b -2a^2
Combine like terms
a^2 +3b = a^2 +4b
-a^2 + 3b -2a^2 = 3a^2 + 3b
Combine like terms
-3a^2 +3b = 3a^2 +3b
a^2 + 3b - 2a^2 = 3a^2 +4b -4a^2
Combine like terms
-3a^2 +3b = -a^2 +4b
a^2 + 3b - 2a^2 = 3a^2 +3b -4a^2
Combine like terms
-a^2 +3b = -a^2 +3b
The left side is the same as the right
Answer:
x = -6
Step-by-step explanation:
you want to solve the aswer so you wanna solve for whats in the parenthesis so your new equation should look like this:
8x + 48 = 3
you want to subtract 48 from both sides your new equation should look like this:
8x = -45
now you want to get x by itself and your new equation should be:
x = -6
