Answer:

The first step of factorising an expression is to 'take out' any common factors which the terms have. So if you were asked to factorise x² + x, since x goes into both terms, you would write x(x + 1) . This video shows you how to solve a quadratic equation by factoring.

Jim rented a truck for one day. There was a base fee of $17.99, and there was an additional charge of 76 cents for each mile dri

dalvyx [7]

Answer:

287 miles

Step-by-step explanation:

The base fee was $17.99 and an additional 76 cents ($0.76) for every mile.

We can represent the amount he will pay for rent with the equation below:

C = 17.99 + 0.76m

where m = number of miles driven

Jim paid $236.11, therefore:

236.11 = 17.99 + 0.76m

0.76m = 236.11 - 17.99

0.76m =218.12

m = 218.12 / 0.76 = 287 miles

Jim drove 287 miles.

Im confused that's all - If 80% is 75 marks, what is full marks

never [62]

Let the full marks be represented by = x

As given, 80% of x is 75

So,

$\frac{80}{100}*x=75$

x= $80x=7500$

x=93.75

Hence, full marks is 93.75

We can check also- $\frac{80}{100}*93.75$ =75
