When you have a scale factor as percentage, is better to convert that percentage into a fraction by divide it by 100%. That way, it will be much easier to scale your figures.

1. 
The scale factor we need to apply to our rectangle is 60%. Firts, lets convert our scale factor into a fraction: \frac{60}{100} = \frac{3}{5}. Next, we just need to multiply each side of our rectangle by our fraction:
length=16( \frac{3}{5})=9.6
width=8( \frac{3}{5} )=4.8
So, our new rectangle will have a length of 9.6 units and a width of 4.8 units.

2. This time the scale factor is 120%. Just as before, lets convert it into a fraction: \frac{120}{100} = \frac{6}{5}, and just as before lets multiply each side of our triangle by our fraction:
base=10( \frac{6}{5} )=12
side=8( \frac{6}{5} )=9.6
So, our new isosceles triangle will have a base of 12 units and tow sides of length 9.6 units each.

3. This time the scale factor is 150%. Just as before, lets convert it into a fraction: \frac{150}{100} = \frac{3}{2}, and just as before lets multiply each side of our polygon by our fraction:
12( \frac{3}{2} )=18
15( \frac{3}{2} )=22.5
13( \frac{3}{2} )=19.5
So, our new polygon will have a side of 12 length units, tow sides of 15 length units, and two side of 15 length units.

4. This time our factor is 75%. Just as before, lets convert it into a fraction: \frac{75}{100} = \frac{3}{4}, and just as before lets multiply each side of our parallelogram by our fraction:
side=25( \frac{3}{4} )=18.75
So, our new parallelogram will have tow sides of length 18.75 units.

Given the equation 5(-2x -10) = 25(x + 1), solve for the value of x that will make the equation true.
brilliants [131]

Answer:

Step-by-step explanation:

5(-2x -10) = 25(x + 1)

-10x - 50 = 25x + 25

by transposing

-10x - 25x = 25 + 50

-35x = 75

x = -75/35

<u><em>x = 15/7</em></u>

or 2.142857..... in decimal

Hope this helps

plz mark as brainliest!!!!!!!

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions:y &gt;
pantera1 [17]

Answer:

Part A: The graph of given inequality is shown below.

Part B: The point (4,6) is not a solution of given system of inequalities.

Step-by-step explanation:

Part A:

The given inequalities are

y>2x+3

y

The related equation of given inequalities are

y=2x+3

y=-\frac{3}{2}x-4

Put x=0, to find the y-intercepts.

y=2(0)+3=3

y=-\frac{3}{2}(0)-4=-4

Put y=0, to find the x-intercepts.

0=2x+3\Rightarrow x=-\frac{3}{2}

0=-\frac{3}{2}x-4\Rightarrow x=-\frac{8}{3}

The x and y-intercepts of first line are (0,3) and (-1.5,0) respectively. The x and y-intercepts of second line are (0,-4) and (-2.667,0) respectively.

Check the given inequality by (0,0).

0>2(0)+3

0>3

This statement is false. It means (0,0) is not the solution of this inequality and the shaded region is opposite side of the origin.

0

0

This statement is false. It means (0,0) is not the solution of this inequality and the shaded region is opposite side of the origin.

The graph of given inequalities is shown below.

Part B:

We have to check whether (4,6) is a solution of the system of inequality or not.

Check the given inequality for the point (4,6).

(6)>2(4)+3

6>11

This statement is false. It means (4,6) is not the solution of given system of inequalities.
