Answer:

\frac{24}{a+3}

Step-by-step explanation:

Dividend = a^{2} -4a+3

Divisor =a+3

Using long division method.

Dividend= (Divisor * Quotient)+Remainder

a^{2} -4a+3=([a+3]*a)+(-7a+3)

a^{2} -4a+3=([a+3]*[a-7])+(24)

Thus the remainder is 24

Since Manuel left the calculation : -7a+3-(-7a-21)= -7a+3+7a+21= 24

Solving his left calculation further we get the remainder 24.

Hence the remainder over divisor is \frac{24}{a+3}

stepan [7]

Answer:

A total of 18 gallons of more gas

Step-by-step explanation:

7 gallons = 210 miles

750-210= 540

210*2 =420 miles       7*2=14 gallons

210/2= 105                  7/2=3.5 gallons

525 miles                       17.5 miles

210/14= 15                      7/14=.5 gallons

540 miles                    18 gallons

Solve each proportion, round to one decimal place.<br> 4/9=x/20
guapka [62]

In order to solve a proportion you need to cross multiply, so you would do:

4x20 and 9xX and you would get...

9x=80

then divide by nine to get

x=8.8888888889

which is technically 8.9
