Answer:

Option B is correct

y = -75x+640

Step-by-step explanation:

The equation of line is given by:

y=mx+b

where, m is the rate or slope and b is the initial amount.

As per the statement:

Wanda has $640 in her checking account.

She pays her landlord $75 per week for rent.

Assume that the number of weeks be x.

Let us assume that the y represented the money in the account after x weeks.

then;

the function becomes,

y = 640-7x

or

y = -75x+640

Therefore, the function best models the linear relationship is, y = -75x+640

The answer is y = 640 - 75x
As her balance starts at a fixed point ( 640)
and decrease every x weeks by 75

Danielle has $6.65 worth of change in nickels and dimes. If she has 5 times as many nickels as dimes, how many of each type of c
evablogger [386]

Answer:

95 nickels 19 dimes

Step-by-step explanation:

d=dimes

5d=nickels

0.05(5d) + 0.10(d) = 6.65

0.25d + 0.10d = 6.65

0.35d=6.65

Divide by 0.35

d= 19 (19 coins)

19 dimes =$1.9

6.65-1.9= $4.75

Nickels=$4.75

4.75/0.05 = 95 coins

19*5=95

  114 coins in total

19*0.10 = 1.9

95*0.05=4.74

4.75+1.9= 6.65

Grace [21]

Answer:

option a) 30 : 19

Step-by-step explanation:

Length = 7 \frac{1}{2} = \frac{15}{2}\\\\Width = 4\frac{3}{4} = \frac{19}{4}

<em><u>Ratio of length to width:</u></em>

      \frac{15}{2} : \frac{19}{4}<em><u></u></em>

    =\frac{\frac{15}{2}}{\frac{19}{4}}\\\\=\frac{15}{2 } \times \frac{4}{19}\\\\=15\times \frac{2}{19}\\\\=\frac{30}{19}\\\\30 : 19
