Mathematics
1 answer:
leva [86]3 years ago
8 0

Remember PEMDAS! Do the parenthesis first so 4x5 is 20. So now write it out as 7^2+20-2^3 now next is exponents. 7x7 is 49 and -2x-2x-2 is -8. now write it as 49+20+-8. Now solve from left to right. 49+20 is 69 now subtract 8 which is 61. 61 is your answer! I hope this worked!

Four times the amount of money in my bank account plus $200 is still two
ioda

Answer:

$700

Step-by-step explanation:

So, I like to extract the information we know and form it into an equation.

So we know that after multiplying what you have in the bank by 4, then add 200 dollars you get two thousand dollars less than a fourth of what's in your dad's bank account.

Your dad has $20,000 in the bank.

Before we write the equation let's find what two thousand less than a fourth of 20,000 is.

20,000/4 = 5,000

Now, 5,000 - 2,000 = 3,000

Ok let's say x is how much money you have

So:

4x + 200 = 3,000

we can isolate the variable by subtracting 200 from both sides

4x = 2,800

then we can divide by 4 on each side

x = 700

so you have $700 in the bank
