Answer: 20
Explanation: Alright, so basically you’re going to want to use PEMDAS (Parenthesis, Exponents, Multiplication/ Division, Addition/ Subtraction)
* just means multiply.. sooo the problem looks like this:
6x(12-7.5)-7
We’ll start at the parentheses :)
So (12-7.5) = 4.5
Now our problem looks like: 6x(4.5)-7
Following PEMDAS, the next thing to come up is multiplication! So we’re going to multiply 6 by 4.5 ...
6x4.5=27
After this our problem looks like: 27-7
So now it’s just simple math...
27-7= 20
Answer:
y= 3/2x -12
Step-by-step explanation:
subract x then u got -2y=-3x+24
divide everythang by -2
then u got y=3/2x -12
Answer:
=6/7
Step-by-step explanation:
Answer:
X = -12
Step-by-step explanation:
-10X + 1 +7X = 37
-10X + 7X + 1 = 37 {Add the like terms}
-3X + 1 = 37 {Subtract 1 form both sides}
-3X + 1 -1 = 37 -1
-3X = 36 {Divide both sides by (-3)}
X = -12
Answer:the answer is 40
Step-by-step explanation:
Because you do 5 times x
