The ratio of the park's length and width is 300/240=5/4
if he takes the length as 10in then the width should be 8in,
so it's area should be 80in²
In this case, you already used 310 minutes out of 500 minutes monthly. So the remaining time for your cell phone should be: 500 minutes -310 minutes= 190 minutes.
You still have 1 week this month, that means the 190 mins time must be divided into 1 week or 7 days. Then the duration you of cell phone use for each day should be: 190 minute/7days= 27.14 minutes/day
The first option
Reflect triangle UTS over the line y=2 and dilate it by a scale factor of 2 from point S
<span>X+(X+2)=32
2X+2=32
2X=32-2
2X=30
X=30/2
X=15 ANSWER FOR THE FIRST ODD NUMBER.
15+2=17 FOR THE OTHER ODD NUMBER.
15*17=255 ANSWER FOR THE PRODUCT OF THESE 2 ODD NUMBERS.</span>
4)
I:3x+4y=67
II:5x-y=35
to eliminate y when they are added one of the equations must contain -ay and the other +ay (with a being some number)
in this case we have in I already a positive term and in II a negative, but they have different numbers
by using multiplication (property of equations) we can multiply II by 4 so the negative and positive parts match
II*4: 20x-4y=140
when I and 4*II get added this results in
3x+20x+4y-4y=67+140
23x=207
5)
in this case I and II were added which can be seen in the left side of the equation((3x+4y)+(5x-y)=8x+3y), so to get the right side we have to also add the right sides 67+35=102
so the full equation would be:
8x+3y=102
