Supplementary means the 2 angles add up to 180 so...
124+(2x+4)=180
124+2x+4=180
124+2x+4-4=180-4
124+2x=176
124-124+2x=176-124
2x=52
2x/2=52/2
x=26
plug in and check
124+2x+4=180
124+2 (26)+4=180
124+52+4=180
176+4=180
180=180
Answer:
3ab^2
Step-by-step explanation:
Factor 6a^2b^3
= 2 * 3 * a * a * b * b * b
Factor 15ab^5
= 3 * 5 * a * b * b * b * b * b
Factor 9a^3b^2
3 * 3 * a * a * a * b * b
Common Factor
= 3 * a * b * b
Simplify
= 3ab^2
Answer:
Um.. Im not sure about this one.. you're in college?
Step-by-step explanation:
inverse means opposite,
inverse of addition is subtraction
The number is = 10x+y
if reverse the digits, the number is: 10y+x
The sum fo its digits is = x+y=5
I suggest this system of equations:
(10y+x)-(10x+y)=27 ⇒9y-9x=27
x+y=5
We can solve this system of equations by equaliztion method
x=5-y
9y-9(5-y)=27
9y-45+9y=27
18y=27+45
18y=72
y=72/18
y=4
x=5-y
x=5-4=1
The number is: 10x+y=10(1)+4=14
Answer: the number is 14
