Alright.
For 7, you'll want to put congruent sides equal to each other, assuming they are parallelograms. So, you'll get the two equations:
3x+2=23
2y-7=9
Solve using GEMDAS/PEMDAS, and you'll get these answers.
3x+2=23
3x=21
x=7
2y-7=9
2y=2
y=1
For 8, you'll want to do the exact same thing, formatting the numbers to equal each other. You'll get these two equations:
3y+5=14
2x-5=17
Solving them would make:
3y+5=14
3y=9
y=3
2x-5=17
2x=22
x=11
For 9, you have to remember that the angle opposite of one angle in a defined parallelogram are congruent. Thus:
130=2h
5k=50
solve them and you get
h=65
k=10

$4/3=$1.33 per pound.
$9/8 = $1.13 per pound.
The second one is cheaper.
D. is the answer
y - y1 = m(x - x1)
the slope is 2/3, so choose which point to be (x1, y1)
A sailboat travels 3 miles in 1.5 hours. How far does it travel in 2 hours.
= 3 miles / 1.5 hours
= 2 miles per hour
= (2 miles) * (2 hours)
= 4 miles in 2 hours.
So, in conclusion, if a sailboat travels 3 miles in 1.5 hours, it travels 4 miles in 2 hours.
Hi,
Since the perimeter of a rectangle is equal to twice the length plus twice the width, what you want to do here is P = 2(8) + 2(x) = 16 + 2x
Hope this helps! If my answer was not clear enough or you’d like further explanation please let me know. Also, English is not my first language, so I’m sorry for any mistakes.
