Find the missing term and the missing coefficient 6a −( )5a =( ) a2 − 35a
andrew11 [14]
Solving for the missing term and the missing coefficient (6a − )5a = ( ) a^2 − 35a
 Let the missing term be X
 Let the missing coefficient be Y
 Therefore, (6a – X)5a = Y(a^2) – 35a
 6a x 5a – X.5a = Y.a^2 – 35a
 30a^2 – X.5a = Y.a^2 – 35a
  Equating co-efficients,
30a^2 = Y.a^2; X.5a = 35a
 30 = Y; 5X = 35
Y = 30; X = 7
   Therefore, (6a-7)5a = 30 a^2 – 35a <span>

What’s 45 divided by 14.04
Vladimir79 [104]

Answer:

3.205

Step-by-step explanation:

convert the decimal number to a fraction

45 \div  \frac{351}{25}

To divide by fraction, multiply by the reciprocal of that fraction

45 \times  \frac{25}{351}

Reduce the numbers with the greatest common divisor 9

5 \times  \frac{25}{39}

Calculate the product

\frac{125}{39}

Now turn it to a decimal which will be

3.20513
