Answer:
x=4
Step-by-step explanation:
here's our equation: 3x=x+8
Our goal: to isolate x onto one side with nothing else on that side.
x is on both sides; we can subtract x from both sides to make the variables and numbers be on different sides
2x=8
Now we can divide by 2
x=4
Hope this helps! :)
Alright, so after a half-life, half of the previous number would be left. So basically,
180 g ← 0 half lives
90 g ← 1 half life
45 g ← 2 half lives
22.5 g ← 3 half lives
11.25 g ← 4 half lives
Therefore, the answer is 11.25 grams
Answer:
where is the equation
Step-by-step explanation:
b^2-4ac>o 2 real #zeros 2 x-intercepts
b^2-4ac=0 1 real number zeros 1 x-intercepts
b^2-4ac<0 0 real number zeros 0 x-intercepts
Answer:
b = 310
Step-by-step explanation:
192 + 118 = b
b = 310
