Shen’s mother gave him $10 to go buy groceries. He picked up a gallon of milk for $3.49, three pounds of oranges that cost $1.14

svet-max [94.6K]

Gallon of milk: $3.49
3lbs oranges: $1.14(3) = $3.42
Box of cereal: $3.46

Front end estimation is taking the number in front and the rest of the numbers coming after it will be zeroes.

Using front end estimation:
$3.49 => $3.00
$3.42 => $3.00
$3.46 => $3.00

Add all these up; Shen estimated the total cost of the groceries would be $9.00.

The table shows transactions from five different bank accounts. Fill in the missing numbers. ( THE IMAGE ATTACHED PLEASE)

velikii [3]

Answer:

Part 1) $A=80$

Part 2) $B=-25$

Part 3) $C=-40$

Step-by-step explanation:

we know that

The old account balance plus the transaction amount is equal to the new account balance

The transaction amount can be a positive number (example a deposit) or a negative number (example a withdrawal)

Part 1) Find the value of A

$432+A=512$

solve for A

subtract 432 both sides

$A=512-432=80$

Part 2) Find the value of B

$75-100=B$

solve for B

$-25=B$

Rewrite

$B=-25$

Part 3) Find the value of C

$C+52=12$

solve for C

subtract 52 both sides

$C=12-52$

$C=-40$

Solve 5t= 150 by using an inverse operation

Taya2010 [7]

Answer:

T=30

Step-by-step explanation:

1) inverse mean opposite, so they want us to solve this equation using the opposite operation

So we can see here that 5 is being multiplied with t, so we should perform the opposite operation, division.

5t=150

(divide both sides by 5)

T=30

Hope this helps

Why is the distributive property appropriate for two-digit multiplication?

Rina8888 [55]

Here's an example:

$25\times93=(20+5)\times(90+3)$
$25\times93=20\times(90+3)+5\times(90+3)$
$25\times93=20\times90+20\times3+5\times90+5\times3$
$25\times93=1800+60+450+15$
$25\times93=2325$
