The sum of a number times 7 and 21 is at least 29. Write as an inequality

PtichkaEL [24]

The inequality is 7x + 21 $\leq 29$

Step-by-step explanation:

DATA:

Let the number be x

Number times 7 = 7*x

Sum of a number times 7 and 21 = 7x + 21

Is at least 29

INEQUALITY:

7x + 21 $\leq 29$

SOLVE:

7x $\leq 29-21$

7x $\leq 8$

x $\leq \frac{8}{7}$

Therefore, the inequality is 7x + 21 $\leq 29$

Carmen is using the quadratic equation (x + 15)(x) = 100 where x represents the width of a picture frame. Which statement about

Alekssandra [29.7K]

We write the equation in the standard form which is:

ax^2 + bx + c = 0

(x + 15)(x) = 100
x^2 + 15x - 100 = 0
(x + 20) (x-5) = 0

The solutions are

x = -20 and x = 5

Therefore, the correct answer is option B. The solution x = 5 should be kept, but x = –20 is unreasonable.

$6 \div 7.74 = \dfrac{6}{7.74}=\dfrac{6\cdot100}{7.74\cdot100}=\dfrac{600}{774}=\dfrac{600:2}{774:2}=\dfrac{300:3}{387:3}=\dfrac{100}{129}$
