Heres a tip, multiply the numbers without any decimals then when done, add how many decimal places there are in total.
Ex:16.28 x 4 = 65.12
1625 x 4 = 6512
Answer:
4(2a+5)
Step-by-step explanation:
4 times 2a= 8a
4 times 5= 20
Were the question too answer sorry ?
First we need to combine like terms:
-18 + 15x = 12x - 18 + 3x
-18 + 15x = 9x - 18
-18 = 9x - 18 - 15x
-18 = -6x - 18
0 = -6x (the 18's cancel)
0 / -6 = x
0 = x
Answer:
I am not sure which one it is due to what you put in. I think it would be A.
x = 0
y = 2/3
Step-by-step explanation:
Step: Solve x + 6y= 4 for x:
x + 6y + −6y = 4 + −6y
x= −6y + 4
Step: Substitute −6y + 4 for x in 2x + 3y = 2:
2x + 3y = 2
2 (−6y + 4) + 3y = 2
−9y + 8 = 2
−9y + 8 + −8 = 2 + −8
−9y = −6
-9y/-9 = -6/-9
y = 2/3
Step: Substitute 2/3 for y in x = −6y + 4:
x = −6y + 4
x = -6 (2/3) + 4
x = 0
Sorry if it is long and confusing. But I hope this helps!
