X= # of miles
.55x+1.75 is greater than or equal to 10

So if she has to go more than 2 miles we will put 2 in for X

.55(2)+1.75 is greater than or equal to 10
.55×2= 1.10+1.75= 2.85
2.85 is greater than 10 is false so now we know she has to go more than 2 miles.

Let's guess and check. Now let's say 15 miles
.55×15= 8.25+1.75= 10
10=10 So she needs to drive at least 15 miles

x is greater than or equal to 15

Please don't solely rely on my answer I don't know if it's correct

The age of a father is two less than seven times the age of his son in two years the sum of their ages will be 57 if the son's p

ASHA 777 [7]

Answer:

$f = 7s -2$

$f + s =53$

Step-by-step explanation:

Given

Let

f = Father's age

s = Son's age

We'll solve this question, while reading through the instructions

From the first statement;

f is 2 less than 7 times s.

This means

$f = 7s -2$

In two years time, the father will be f +2 and the son will be s + 2

So, their sum is:

$(f+2) + (s + 2) = 57$

$f + 2 + s + 2 =57$

Collect like terns

$f + s =57-2-2$

$f + s =53$

So, the equations are:

$f = 7s -2$

$f + s =53$
