Sort out:

12.) Natasha has $196 and wants to buy a computer for $698. How much more do you need?

13.) Toni has $406 in her checking account. He is paid $78 for a part-time job and deposits it into his checking account. What is the balance in your account now?

14.) A beverage company packed 228 cans of soda in 12-can cases. How many cartons were filled?

Step-by-step explanation:

Round to the nearest ten, hundred, or thousand:

1. 6,471 to need to the nearest thousand is 6,000

Estimate each sum, difference, or product by first rounding to the nearest hundred.

2. 41,348 + 19,749 ==> 41,300 + 19,700 = 61,000

3. 38,652 - 14,549 ==> 38,700 - 14,500 = 24,200

4. 396 • 748 ==> 400 • 700 = 280,000

Solve the equations:

5. t + 28 = 5

      - 28   -28

t = 26

6. 28x = 168

  /28       /28

x = 6

7. 27 = y + 12

-12          - 12

15 = y or y = 15

Simplify:

8. 10 • 24 - (18 + 2) ÷ 4 - (9 - 7)

10 • 24 - 20 ÷ 4 - 2

240 - 5 - 2

240 - 7

233

9. (80 ÷ 16) x [(20 - 56 ÷ 8) + (8 • 8 - 5 • 5)]

(80 ÷ 16) x [(20 - 56 ÷ 8) + (64 - 25)]

5 x [(20 - 7) + (64 - 25)]

5 x [13 + 39]

5 x 52

260

Sort out:

12. Natasha has $196 and wants to buy a computer for $698. How much more do you need?

698 - 196 = $502 <== final answer

13. Toni has $406 in her checking account. He is paid $78 for a part-time job and deposits it into his checking account. What is the balance in your account now?

406 + 78 = $484 <== final answer

14. A beverage company packed 228 cans of soda in 12-can cases. How many cartons were filled?

228/12 = 19 cartons filled <== final answer

Hope this helps!

The answer is in the image 

Cost of 7 gallons=$24.50

Cost of 1 gallon=24.50/7=3.5

Cost of 15 gallons=15*3.5=52.5

Cost of 15 gallons will be $52.5

The total nom of  code that can be used is equal to 5+3 = 8

y=2x+15

where y=Value of coin

x=Age in years

Value of coin after 19 years=2*19+15

=$53

Therefore, Value after 19 years=$53

The answer is in the image 

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

Approximately it is aqual to 1300kg

Salesperson will make 6% of 1800

=(6/100)*1800

=108

Salesperson will make $108 in $1800 sales
