Answer:

x=\frac{12}{5}

x=2.4

Step-by-step explanation:

6x+2\left(2x-3\right)=18

<u>Expand 2(2x-3) by applying Distributive law:</u>

<u />2\times \:2x-2\times \:3

Multiply:

2\times \:2x=4

2\times \:3=6

4x-6

6x+4x-6=18

<u>Combine like terms:</u>

6x+4x=10x

10x-6=18

<u>Add 2 to both sides:</u>

10x-6+6=18+6

10x=24

<u>Divide both sides by 10:</u>

\frac{10x}{10}=\frac{24}{10}

x=\frac{12}{5}

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:

<u>DATA:</u>

Let the number be x

Number times 7 = 7*x

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

Is at least 29

<u>INEQUALITY:</u>

7x + 21 \leq 29

<u>SOLVE:</u>

7x \leq 29-21

7x \leq 8

x \leq \frac{8}{7}

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

I’m stuck on these questions
jolli1 [7]

Answer:

In my opinion both of the lines are tangent.

Step-by-step explanation:

Because a tangent to a circle is a straight line which touches the circle at only one point. This point is called the point of tangency. The tangent to a circle is perpendicular to the radius at the point of tangency.
