Answer:
Given m∠RST = (15x - 10)o
Using angle addition postulate:
m∠RST = m∠RSP + m∠PST (15x - 10)= (x + 25)+ (5x + 10)(15x - 10)=
so your answer would be (6x+35)
Step-by-step explanation:
Answer:
Original price reduced by 30%
Step-by-step explanation:
You want the deepest discount, which means you want the greatest percent/amount off. The first choice is 20%. The second is 30%. The third one is 25%, because you are paying for 75% (100-75). The second choice offers the deepest discount because it is 30% off.
Answer c I’m pretty sure
Step-by-step explanation:
Answer:
479.85
Step-by-step explanation:
1 Simplify 15% to 0.15.
x+0.15=480
2 Subtract 0.15 from both sides.
x=480-0.15
3 Simplify 480-0.15 to 479.85479.85.
x=479.85
Answer:
Yes
Step-by-step explanation:
The theory is that the two shortest sides must be greater than the longest side, so for the first one 3+5=8, 5<8. Then you can do the rest by yourself.
