Twice the difference of a number and 7 equals 5

RideAnS [48]

Hey there!

Let's write an equation given this information. We will use x to represent the number.

2(x-7)=5

Now, we use the distributive property to remove the parentheses.

2x-14=5

Now, we add 14 to both sides.

2x=19

We divide both sides by 2.

x=9.5

Therefore, our number is 9.5

I hope this helps!

According to a state law for vehicles traveling on state roads, the maximum total weight of a vehicle and its contents depends o

Alex787 [66]

Inequalities are used to show the relationship between unequal expressions.

The inequalities that represent the maximum weights are:

2 axles - $x \le 40000$ .
3 axles - $x \le 60000$ .
4 axles - $x \le 80000$ .

Let the maximum weight be represented with x

In inequality, maximum means less than or equal to i.e. $\le$

(a) 2 axles

The maximum weight, here is 40000.

So, the inequality is:

$x \le 40000$

(b) 3 axles

The maximum weight, here is 60000.

So, the inequality is:

$x \le 60000$

(c) 4 axles

The maximum weight, here is 80000.

So, the inequality is:

$x \le 80000$

See attachment for the graphs of each inequality

Polygon q is a scaled copy of polygon p using a scale factor of 1/2 polygon q’s area is what fraction of polygon p’s area?

san4es73 [151]

Answer:

Polygon q’s area is one fourth of polygon p’s area

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z-----> the scale factor

x-----> polygon q’s area

y-----> polygon p’s area

$z^{2} =\frac{x}{y}$

In this problem we have

$z=\frac{1}{2}$

substitute

$(\frac{1}{2})^{2} =\frac{x}{y}$

$(\frac{1}{4}) =\frac{x}{y}$

$x=\frac{1}{4}y$

therefore

Polygon q’s area is one fourth of polygon p’s area
