Answer:
24, 48, 108
Step-by-step explanation:
2:9:4
2x+9x+4x=180
15x=180
x=12
2(12)=24

Answer:
When ordering fractions, you don't only have to take in account for the numerator, you also have to take into account the denominator, whereas with whole numbers, you only have to take into account the numerator. Also, in a fraction, you have to make sure the denominators are the same before ordering them.
Answer:
5x^2y is the GCF for 15x2y3 and -20x3yz.
Step-by-step explanation:
The tip is $15.73. I get that by multiplying 78.63 and .20. then you add the tip to the bill and get $94.36. you then find the discount by multiplying 94.36 and .15. the discount is 14.15. then subtract 14.15 from 94.36 to get your total.
the answer is $80.21
Answer:
(3,1)
Step-by-step explanation:
Since both equations are equal to y, we can set them equal to each other
y = 3x-8
y = 4-x
3x-8 = 4-x
Add x to each side
3x+x-8 = 4-x+x
4x-8 = 4
Add 8 to each side
4x-8+8 = 4+8
4x = 12
Divide each side by 4
4x/4 =12/4
x=3
Now we can find y
y = 4-x
y = 4-3 =1
