Step-by-step explanation:
7 X + 8 = X+12 + 3X+20
3 X = 24
X= 8
m< RPQ = 8+12 = 20
Prime factorization is simply making a number become simplified in the smallest term it can be in. For example 9 Can be broken down into 3 times 3. Your prime numbers are 2, 3, 5, 7, 11, 13, 17,19 because nothing times something will give you that number besides itself and 1
To find slope you can do Y2-Y1/X2-X1 Which will get you rise over run which is slope so I would choose the two whole number points and do those! I hope this is right lol! and i hope it helped!
Answer:
AED = 136
Step-by-step explanation:
AED and DEB form supplementary angles, which mean they add to 180 degrees.
AED + DEB = 180
AED +44 = 180
Subtract 44 from each side
AED +44-44 = 180-44
AED = 136
Answer:
- original cost: $195.00
- % discount: 16%
Step-by-step explanation:
I wouldn't mess with trying to set up proportions. That seems an inappropriate tool for this. Instead, make use of the known relationships between the various prices:
original cost - discount amount = discounted price
Adding the discounted amount to both sides of this equation gives ...
original cost = discounted price + discount amount
original cost = $163.80 + 31.20
original cost = $195.00
_____
The percentage discount is ...
percent discount = (discount amount)/(original cost) × 100%
= $31.20/$195.00 × 100%
= 16%
The percentage discount is 16%.
