3.3-×=3(x-1.7) I need help on this
2 answers:
So as before:
do the same to both sides
with one unknown, get it on one side so
3.3-x=3(x-1.7)
so distribute meaning multiply x and -1.7 by 3 (remember that negative times positive =negative)
3.3-x=3x-5.1
I usually like positive unknowns so
add x to both sides
3.3=4x-5.1
add 5.1 to both sides
8.4=4x
divide both sides by 4
2.1=x
3.3- x = 3( x-1.7)
3.3 - x = 3x - 5.1
8.4=3x+x
8.4=4x
8.4/4=x
x=2.1

Answer:
x=13 and y =6
Step-by-step explanation:
y=x-7
y=6
Substitute y=6 into the first equation
6 = x-7
Add 7 to each side
6+7= x-7+7
13 = x
x=13 and y =6
Answer:
1.1888 (8 goes on forever) seconds to travel from the satellite to Earth.
Step-by-step explanation:
It is traveling at 3 x 108 m/s and needs to travel 3.6 x 107 m. 3 x 108=324 and 3.6 x 107=385.2 so 324 m/s for 385.2 m. 385.2/325=1.1888.
-2, -5, -8
You're subtracting three each time.
Answer:
C. x - 4
Step-by-step explanation:
The best way to do this is to first take out GCF
6(x² - x - 12)
Then we factor
6(x - 4)(x + 3)
We can now see our answer.
It will quarter the result. (I think so)
