Just work this problem out backwards. First write out an equation.
(x+4)•3=30
Now solve :
(x+4)•3=30
3x+12=30
-12 -12
3x=18
/3 /3
x=6
Your answer is 6!
Hoped I helped!
14. Was the perimeter calculated correctly?
- Breadth = 1 *2/5 yards = 7/5 yards
We know that,
Perimeter of rectangle = 2 ( l + b )
= 2 ( 4 + 7 / 5 )
= 2 ( 20 + 7 / 5 )
= 2 × 27/5
= 54 / 5
= 1 * 4/5
No ...
Answer:
slope = m = 3/7
y-intercept = b = -5
Step-by-step explanation:
y = mx + b is the slope-intercept form of the equation of a line
where m = slope, and b = y-intercept.
slope = m = 3/7
y-intercept = b = -5
I think it's RO if it's circle O
