Answer:
a = -15, b = -.5, c = -1
Step-by-step explanation:
1/3a = -5 --> multiply each side with 3 --> a = -15
12 - b = 12.5 --> subtract 12 from both sides --> -b = .5 --> multiply each side with -1 to get b positive --> b = -.5
.1 = -10c --> multiply each side with -10 --> c = -1
The answer is x=22 because you just have to add the two equations together and then solve for 8x+4=180
Answer:
Step-by-step explanation:
Hi!
So, a radical is basically a fractional power.
Square roots are numbers to the 1/2.
For example, the square root of 4 is just 
, or 2.
So for cube root, the 1/2 changes to a 1/3.
This can then be rewritten as 
or
Okay do 4*10 and 7*10 (you get 40/70) and then do 3*7 and 10*7 (so now you've got 21/70) then add 21/70+40/70 and that's the total distance
