Find the Least Common Denominator (LCD) which is 28.
-1/4 (7) = -7/28
-3/7 (4) = -12/28
-7 - 12 = -19
-19/28
Simplify if you can.
Answer:
x= -21
Step-by-step explanation:
-1/3=7/x
-1x=21
-1x/-1=21/-1
x= -21
1/10x200
= 1/10x200/1
= 200/10
=20
the answer is 20
if u dont understand, 1/10 means a part of 200 that is divided by 10 which means the number x10 =200. So if u dont understand, you can check answer this way: n*10=200
200/10=n
n= 20
Answer:
2
Step-by-step explanation:
9x=8+5x
9x-5x=8
4x=8
x=8/4
x=2
To find the slope, use the equation slope=rise/run.
rise= 7-(-1) = 8
run = 4-1 = 3
The slope is 8/3
