Answer:
x=2 and y=7
Step-by-step explanation:
Step: Solvey=2x+3for y:
y=2x+3
Step: Substitute2x+3foryiny=3x+1:
y=3x+1
2x+3=3x+1
2x+3+−3x=3x+1+−3x(Add -3x to both sides)
−x+3=1
−x+3+−3=1+−3(Add -3 to both sides)
−x=−2
−x
−1
=
−2
−1
(Divide both sides by -1)
x=2
Step: Substitute2forxiny=2x+3:
y=2x+3
y=(2)(2)+3
y=7(Simplify both sides of the equation)
In order to round to the nearest 100 you look at the 10s place.
It's 7 which means we round up. So 178 rounded to the nearest 100 is 200.<span />

Answer: answer is in the photo
Step-by-step explanation:
From 2 to 101 , the perfect square numbers are ,
- 4 , 9 , 16 , 25 , 36 , 49 , 64 , 81 , 100 .
Total number of possible outcomes = 100.
Total number of favourable outcomes = 9 .
Hence ,
→ <u>P ( of getting perfect square ) = 9/10</u><u>0</u>
