For the given values of n and d, find integers q and r such that n = dq + r and 0 ≤ r < d. n = −67, d = 8

Firlakuza [10]

Answer:

$q = 8$

$r = 3$

Step-by-step explanation:

Given

$n = dq + r$

$0 \le r < d$

$n = 67$ --- not -67

$d = 8$

Required

Find q and r

Substitute values for d and b

$n = dq + r$

$67 = 8 * q + r$

$67 = 8q + r$

Make q the subject

$q = \frac{67 - r}{8}$

$0 \le r < d$ means that r is less than 8 but greater than or equal to 0

And r and q are integers.

Let $r = 3$

$q = \frac{67 - 3}{8}$

$q = \frac{64}{8}$

$q = 8$

No other true values of r and q can be gotten.

Wyatt is working two summber jobs, washing cars and tutoring. He must work no less than 12 hours altogether between both jobs in

stiv31 [10]

Answer:

$w+t\geq 12$

Step-by-step explanation:

Please consider the complete question.

Wyatt is working two summer jobs, washing cars and tutoring. He must work no less than 12 hours altogether between both jobs in a given week. Write an inequality that would represent the possible values for the number of hours washing cars, w, and the number of hours tutoring, t, that Wyatt can work in a given week.

The number of hours altogether between both jobs would be $w+t$ .

Since Wyatt must work no less than 12 hours altogether between both jobs in a given week, so hours in both jobs should be greater than or equal to 12. We can represent this information in an inequality as:

$w+t\geq 12$

Therefore, our required inequality would be $w+t\geq 12$ .
