Answer:

Area= 4,200 square feet

Step-by-step explanation:

If I read your question correctly, I'm assuming the dots (".") mean a multiplication sign ("x").

If they are all being multiplied, use PEMDAS to solve this. First, find to value for any exponents you have (in this case, it's 2^3 and 5^2).

2^3=2*2*2=8\\5^2=5*5=25

Now that you have the values for these two exponents, multiply all the numbers together.

8 x 3 x 25 x 7 = 4,200

Marco is reconstructing his expenses for the past two weeks. Here are the records of his expenses: Transaction Cost ($) T-shirt
Stella [2.4K]

The total expenses of Marco's account are $174. The ending balance is $81. So, the starting balance will be $255.

Option A is correct for starting balance.

Further Explanation on Starting and Ending Balance

Given that Marco’s bank statement says that he has an ending balance of $81. The expenses $ of Marco is given as,

  • T-shirt 20
  • Gas 22
  • Movie 13
  • Video game 39
  • Jeans 34
  • Hat 15
  • Books 31

The total expenses can be calculated as given below.

Total Expenses = Sum of all Expenses

Total Expenses = 20+22+13+39+34+15+31

Total Expenses = $174

The starting balance can be calculated as given below.

Starting Balance = \$174 +\$81

Starting Balance = $ 255.

Hence we can conclude that the starting balance of Marco's account is $255. Option A is correct.

X+y=5<br> x×y=6<br> Solve simultaneously with steps
igor_vitrenko [27]

Answer:

(3, 2), (2, 3)

Step-by-step explanation:

x + y = 5

xy = 6

Solve the first equation for x.

x = 5 - y

Substitute 5 - y for x in the second equation.

xy = 6

(5 - y)y = 6

5y - y² = 6

y² - 5y + 6 = 0

Factor.

(y - 2)(y - 3) = 0

y - 2 = 0  or y - 3 = 0

y = 2  or y = 3

Now substitute 2 for y in the first equation and solve for x.

x + y = 5

x + 2 = 5

x = 3

One solution is x = 3; y = 2, or (3, 2).

Now substitute 3 for y in the first equation and solve for x.

x + y = 5

x + 3 = 5

x = 2

Another solution is x = 2; y = 3, or (3, 2).

Answer: (3, 2), (2, 3)
