Answer:
they are both alike because you're dividing both equations by 2 . in both equations you're trying to get the variable by itself .
they are both different because both of the equations have a different x= . in equation 1 you subtract and in equation 2 you would add .
Step-by-step explanation:
For 2x+4=20 you would make +4 negative 4 to get the variable by itself .
then you'd subtract the numbers 20-4=16
then divide both sides by 2 2÷2 and 16÷2
x=8 is your answer
for 2x-4=20 you would make -4 and make it positive 4 to get the variable by itself
then you'd add the numbers 20+4
then divide both sides by 2 2÷2 and 24÷2
x=12
All you would have to do is divide 1,845 by 10 to get the answer which is $184.50 to each classroom
The factors of 52 is 1 2 4 13 26,
Answer: 12
Step-by-step explanation:
Distribute the 9(x-11) first. If you distribute it, it becomes 9x-99
9x-99=9
Add 99 to both sides
9x=108
Divide by 9 on both sides
X=12
Answer:
There are 11 g of drink mix for every ounce of water.
Step-by-step explanation:
In order to calculate the unit rate in grams of drink mix for ounces of water of any type of drink, we need to divide the mass of drink mix in grams by the mass of water in ounces. In this case there are mixed fractions, we will first convert them to fractions, to do that we sum the fraction part with the integer one.
The rate is:
There are 11 g of drink mix for every ounce of water.
