Answer:

The total number of polo shirts is 50

Step-by-step explanation:

Let

x -----> the number of white polo shirts

y -----> the number of blue polo shirts

we know that

x=y+18 -----> equation A

68\%=68/100=0.68

x=0.68(x+y) ------> equation B

substitute equation A in equation B and solve for y

y+18=0.68(y+18+y)\\ y+18=0.68(2y+18)\\ y+18=1.36y+12.24\\ 1.36y-y=18-12.24\\ 0.36y=5.76\\ y=5.76/0.36\\ y=16\ blue\ polo\ shirts

<u><em>Find the value of x</em></u>

x=16+18=34\ white\ polo\ shirts

<u><em>Find the total number of polo shirts</em></u>

x+y=34+16=50\ polo\ shirts

Zaid and Matias, two farmers, constructed a 792 foot fence around their very large garden. Zaid agreed to construct 20% more of
likoan [24]

Answer:

1.2x +x =792

2.2x =792

And we got finally:

x =\frac{792}{2.2}= 360 ft

And the amount for Zaid would be 1.2*360 ft= 432ft

So then Zaid construc 432 ft and Matias 360 ft

Step-by-step explanation:

For this case we know that Zaid and Matias, two farmers, constructed a 792 foot fence around their very large garden so then the total is represented by 792 ft

We also know that Zaid agreed to construct 20% more of the fence than Matias did. Let's assume that the amount that construct by Matias was x then the amount constructed by Zaid would be 1.2 x representing 20% more than Matias and we can set up the following equation:

1.2x +x =792

2.2x =792

And we got finally:

x =\frac{792}{2.2}= 360 ft

And the amount for Zaid would be 1.2*360 ft= 432ft

So then Zaid construc 432 ft and Matias 360 ft

Which numbers are 4 units from -2 on the number line
Artemon [7]

Let the number be x


Then the absolute value of the number from -2 should be 4


|x--2|=4


|x+2|=4


So either



(x+2)=4


x=4-2=2


Or


-(x+2)=4


x+2=-4



x=-4-2



x=-6



[tex] <B>The numbers are 2 and -6</B> [/tex[


They are four units away from -2 on the number line
