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
Answer:
Multiply both denominator&numerator by 2
Step-by-step explanation:
3/5 = (3×2)/(5×2)
= 6/10
= 0.6
Answer:

Step-by-step explanation:
first, you have to find the slope, and to do that you use this equation 
so, now to insert your points (0,-4), (-1,4)
(x1,y1) (x2,y2)

now that you have the slope you can find the y-intercept of the slope-intercept form by looking at your first point (0,-4) and get -4
- if you were to look at this point on a graph it would be on the y-axis therefore, -4 is the y-intercept [if you don't have a point like this one then you can look at a graph with one of your points and make a slope until you are on the y-axis :)]
therefore, the slope-intercept form is y=
-4
[ps, your slope is a zero slope :)]
Answer:
x = 7
Step-by-step explanation:
3x - 7 = 2x
- 7 = -1x
x = -7/-1
x = 7
