So,
To get rid of the fractions, find the LCM of the denominators.
LCM of 4, 3 = 12
Multiply both sides by 12.
3x +60= 4x +120
Subtract 3x from both sides.
60 = x + 120
Subtract 120 from both sides.
x = -60
Check.
-15 + 5 = -20 + 10
-10 = -10
This checks.
S = {-60}
Answer:
a) x=-15
b) x= 27
c) x=14
Step-by-step explanation:
a) x/-3+1=6 x/-3=5 (-3)x/-3=5(-3) x=-15
-1 -1
b) 3-x/9=0 -x/9=-3 (-9) -x/9=-3(-9) x=27
-3 -3
c) x/-2+4=-3 x/-2= -7 (-2)x/-2= -7(-2) x=14
-4 -4
Answer:
56
Step-by-step explanation:
Basically you want to find out what is 70% of 80.
first you have to set up your problem
= 
the first fraction would be the percent (70) over 100. (you always use 100)
The fraction to the left would be n over 80. the denominator (the number on the bottom) would be the whole amount. n would be the unknown number
To solve you would use the butterfly method. 80 x 70 and 100 x n. 80 x 70 is 5600 and 100 x n is 100n.
The final step is dividing. 5600 divided by 100 giving you 56
Answer:
v0 + 1/2at
Step-by-step explanation: Given that the distance a race car travels is given by the equation d = v0t+12at2 where v0 is the initial speed of the race car, a is the acceleration, and t is the time travelled.
The equation for the driver's average speed s during the acceleration will be:
(v0t+12at2) / t
Since Average speed is equal to distance divided by time.
Therefore, the equation will be:
v0+1/2at
