Answer:
B
Step-by-step explanation:
Expressing the ratios as fractions, that is
=
( cross- multiply )
a = 3b
=
( cross- multiply )
c = 5b
------------------------------------------
Given
, substitute values from above for a and c
= 
= 
=
← cancel b on numerator/ denominator
=
→ B
Line 1 and 2 are parallel
line 1 and 3 are parallel
line 2 and 3 are parallel
First, you have to simplify the equation:
y+3 = 3(x+5)
y+3=3x+15
So you multiply what’s inside the brackets (x+5) by the factor (3). So 3•x=3x, 3•5=15.
Then you rearrange the equation as necessary to convert it into standard form, which is Ax + By = C
Answer:
Step-by-step explanation:
let x be the number
6+1/5x=12
1/5x=12-6
1/5x=6
x=5*6
x=30
check: 6+(1/5*30)=6+6=12
