A = 5 + B
A + 5 = 2B
Let's get one of the variables on one side.
A = 5 + B
A = 2B - 5
By the transitive property
5 + B = 2B - 5
Solve for B.
5 = B - 5
10 = B
Use 10 = B in an earlier equation to find A.
A = 5 + B
A = 5 + 10
A = 15
Abe has 15$ and Ben has 10$.
Answer:
When c and a are positive or both are negative
Step-by-step explanation:
negative times negative equals positive so if a was negative and c was negative -a*-c= ac
Of course positive times positive equals negative so if a and c were positive we could do
a*c= ac
Hope I could help !
I used a calculator and it said the answer is 430858661.
The only way I know how to do this sort of long sum is with a calculator....
All you need to do is input 43789 * 9 + 138 * 12 - 1345 + 124556 x 3456 - 1287 and you will get the answer. Converted the words into the numerical symbols like times to *
If you want it to be more readable add commas so it's 430,858,661. You do it every 3 numbers.
You'll want to do it the right order of operations since not all calculators do this automatically and it's a good habit >_>, using an acronym like BIDMAS (using the brit acronym lol) is a good way to remember this (<span>Brackets, Indices, Division, Multiplication, Addition, Subtraction)
So you'll need to do the multiplication first and then the addition and then the subtraction so this is the correct order. You want to use the brackets so it does it in the right order.
(43 789 * 9) + (138 * 12) - 1345 + (124 556 x 3456) - 1287</span>
Answer:
Sandy did not follow PEMDAS and added first instead of doing her multiplication and division and then her addition and subtraction the answer would be 18
