The solution of the inequality 3x + 1 < 7 is \boxed{x < 2}.

Further explanation:

There are two types of the interval close interval and open interval.

If the values of \text{x} doesn’t includes the number than it is represented by hollow dot on the number line and if the values of \text{x} includes the number than it is represented by the solid dot on the number line.

Given:

The inequality is 3x + 1 < 7.

Explanation:

The given inequality is 3x + 1 < 7.

Subtract 1 from both side of the inequality.

\begin{aligned}3x + 1 - 1 &< 7 - 1\\3x &< 6\\\end{aligned}

Now divide both sides by 3.

\begin{aligned}\frac{{3x}}{3} &< \frac{6}{3}\\x&< 2\\\end{aligned}

The solution of the inequality 3x + 1 < 7 is \boxed{x < 2}.

3x + 1 < 7...subtract 1 from both sides
3x < 7 - 1
3x < 6 ...divide both sides by 3
x < 6/3
x < 2

there will be an open circle on 2....because the problem has no equal sign...the line will be shaded to the left...because it is less then.

A special deck of cards has ten cards. Four are green, three are blue, and three are red. When a card is picked, its color of it
nata0808 [166]

Answer:

P(A) = 3/20

Step-by-step explanation:

P(A)=P(blue)P(head)=(3/10)(1/2)=3/20

as there are 10 cards in total, out of which 3 are blue so the probability to get the blue card is, P(blue) = 3/10. and the probability of getting a head when a coin is tossed is P(head) = 1/2.

So in total

P(A) = P(blue)*p(head) = (3/10)*(1/2) = 3/20 = 0.15
