You have to get from $30 to $21.75
21.75/30=0.725 x 100= 72.5% of the original price
Answer:
The answer to your question is the first option
Step-by-step explanation:
Write the division
7x³ - 7x² + 6x +4 Result
x + 1 7x⁴ - 0x³ - 1x² + 10x + 15
-7x⁴ - 7x³
0 - 7x³ - 1x²
+ 7x³ +7x²
0 + 6x² + 10x
- 6x² - 6x
0 + 4x + 15
- 4x - 4
0 + 11 Remainder
Result = 7x³ - 7x² + 6x + 4 + 11 / x + 1
Answer:
28%
Step-by-step explanation:
you can divide 276 by 100 to get how much each individual percentage is worth so when you multiply that number by 28 you get 77.28
Answer:
y=10°
Step-by-step explanation:
Here,
→(3x+18)°=(5x-4)°
→18°+4°=5x-3x
→22°=2x
→x=11°
Also,
3(4y+3)°+5x-4°=180°[The sum of the linear pair is 180°]
12y+9°+5x-4°=180°
12y+5°+5×11°=180°
12y+5°+55°=180°
12y=180°-60°
12y=120°
y=120°/12
y=10°
Answer:
k=-2
Step-by-step explanation:
Using substitution to find what you're missing, (in this case k) is when you plug each letter into the other equation:
-4k+3=3k+17
So now solve for k:
subtract 3 from both sides...
-4k=3k+14
subtract 3k from both sides to combine with -4k...
-7k=14
divide -7 from both sides...
k=-2
