Myra had a balance of 802.76 in her checking account. She wrote a check for 52.76 and wrote that she had 780.00 remaining. Use estimation to explain why this cannot be the correct balance in her checking account

here

Step-by-step explanation:

she had 750.00 i

ignore the decimal

802-52=750

then 0.76-0.76=0

and that gives you 750.00

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.

answer is x<
