So PEMDAS is order of operations basicly.
P=Parenthesis
E=Exponets
M=Multiplication
D=Division
A=Addition
S=Subtraction
For example: 2x4+(9x9)-1
When solving order of operations you ALWAYS start with the problem in the parentheses.
(9x9)=81
Now multiplication comes next so, 2x4=8
Then addition, 8+81=88
Lastly subtraction, 88-1=81
I think the answer is C. 1,320
3x=12
You want to find x so isolate x to find what the value is.
So divide the whole equation by 3 to make x by itself.
(3x)/3=12/3
x=12/3
x=4
Check your answer:
3(4)=12
Yes, 3 times 4 is 12.
Hope this helps :)
Answer:
A. 1,000 ml milk B. 3,500 g flour
Step-by-step explanation:
Divide: 250 divided by 8. You get 31.25.
Multiply: 31.25 times 32. You get 1,000
Divide: 140 divide by 8. You get 17.5
Multiply: 17.5 times 20. You get 3,500
Hope I helped!! :) Sorry if it's wrong! :(
