Answer:

$C=0.65M+22.65$

Step-by-step explanation:

The standard charge includes an initial fee and plus an addditional fee for each mile driven and is given by:

$S=0.40M+17.75$

The insurance charge is given by:

$I=0.25M+4.90$

So, the total charge C will be the sum of the standard charge S and the insurance charge I:

$C=S+I$

Substitute:

$C=(0.40M+17.75)+(0.25M+4.90)$

Rearrange:

$C=(0.40M+0.25M)+(17.75+4.90)$

Add:

$C=0.65M+22.65$

And we have acauired our equation relating C to M!

What value of c makes the trinomial below a perfect square x2 + 7x + c?

Daniel [21]

We have that
x² + 7x + c
Group terms that contain the same variable
(x² + 7x )+ c
Complete the square. Remember to balance the equation
(x² + 7x+3.5² )+ c-3.5²

Rewrite as perfect squares

(x+3.5)²+ c-3.5²
so
c-3.5² must be zero
c-3.5²=0------- c=3.5²------> c=12.25

the answer is
the value of c must be 12.25

Answer:

Step-by-step explanation:

Cost price (CP) = Purchase amount + amount spend on repairing

= 85000 + 5000

= ₹ 90000

Profit % = 10%

$SP = \frac{100+Profit}{100}*CP\\\\=\frac{100+10}{100}*90000\\\\ = \frac{110}{100}*90000$

= ₹ 99000
