Answer: i think it’s A and D
Answer:
$9 or 9% less
Step-by-step explanation:
Original Price = OP
$75= OP
75 x .2 (20% discount) = 15
$15 discount
$75 - $15 = $60
$60 x .1 (service fee) = 6
$60 + $6= $66
Op ($75) - $66 = 9
$9 less than OP
How I check the percentage (probaly not how ur supposed to but ah well)
75 = 100%
75 + 25 = 100 but 25 more than 100%
66 + 25 = 91, also makes 75 100% again
100%-91%=9%
Answer:
True depending on what you are comparing it to.
Step-by-step explanation:
A pulley would help lighten the load that you are trying to pull up, which may make it easier for you to get the load to your designated area. The more complicated it is, usually the more 'lighter' it becomes, or the less force you have to exert.
For example, you will have to give a 100% energy in trying to life a heavy box. However, if you use a simple pulley (only one), you may only have to exert 75% more energy, for the weight is significantly lower.

Answer: -2/5
Step-by-step explanation:
To find the slope, we set the function use y = mx + b forms.
2x + 5y = 10
5y = -2x + 10 Minus 2x in both side
y = -2/5x + 10/5 Divide 5 from both side
y = -2/5x + 2
In the y = mx + b, the m before variable x is always the slope, so -2/5 is the slope for 2x + 5y = 10.
