Alchen [17]

Answer:

The expression is $x=100-15-10+20-40+35$

Jake has in his wallet $\$90$

Step-by-step explanation:

Let

x-----> the money that Jake has in his wallet

we know that

The expression that represent the situation is equal to

1) Jake has $100 of birthday money in his wallet

so

$x=100$

2) He spends $15 at Twistee Treat and $10 at Wawa

so

$x=100-15-10$

3) He finds a $20 bill on the ground

so

$x=100-15-10+20$

3) His friend borrows $40 from Jake

so

$x=100-15-10+20-40$

4) At home, Jake mows the lawn and earns $35

so

$x=100-15-10+20-40+35$

$x=\$90$

A "principal square root" is always...

vladimir1956 [14]

Really none of the above.

A principal square root of a real number is a positive real number (or a positive real number times i, if you're up to complex numbers, but let's assume not.) It's not necessarily a positive integer, √2 being the obvious example.

Is √2 a positive fraction? We can write it as √2 / 1 so I suppose it is. It's certainly not a rational number. Even if we grant irrationals as fractions surely √0=0 isn't a positive fraction. So "always" isn't correct.

I'd go with none of the above, but if I had to choose I'd choose D.
