7x +(3x-5)+(8x+5)=180
simplify
18x=180
divide by 18
x=10
Answer:
x=4
Step-by-step explanation:
Angles 2 and 7 are alternate exterior angles which means they are congruent and have equal measures. This means you can write 3x+2=x+10 and solve for x.
3x+2=x+10
3x-x+2=x-x+10
2x+2=10
2x=8
x=4
Answer:
The original selling price would be $ 515.87 ( approx )
Step-by-step explanation:
Let x be the original selling price ( in dollars ),
After marking down 10%,
New selling price = x - 10% of x = x - 0.1x = 0.9x
Again after marking down 30%,
Final selling price = 0.9x - 30% of 0.9x
= 0.9x - 0.3 × 0.9x
= 0.9x - 0.27x
= 0.63x
According to the question,
0.63x = 325

Hence, the original selling price would be $ 515.87.
