To solve equations, you want to isolate the X. So, the first step will be to distribute that 4 into the 2x + 1.
4 x 2 = 8
4 x 1 = 4 So we have 4(2x+1) = 8x+4. When we plug this into the equation, that gets us 8x + 4 - 2x = -8. Next, let's combine like terms now that we've distributed everything out. 8x - 2x = 6x. Now we have
6x + 4 = -8. Next, we subtract 4 from both sides to isolate the X; 6x = -8 - 4. -8 - 4 = -12. So now we have 6x = -12. The final step to isolating the X is to divide both sides by 6; 6/6 = 1, and -12/6 = -2. Our final answer is X = -2.
<u>Answer:</u>
3 months
<u>Explanation:
</u>
Amount saved in Gina’s saving account= 250
Amount Gina puts in her account each month= 4% of 3100
=
= 4 × 31
= 124
Hence total amount added in each month =124
Therefore money credited x months
= 250 + 124 x
Amount saved in Rodger’s account = 350
Amount Rodger puts in his account each month = 3% of 2900
=
=87
Hence total amount added in each month = 87
Therefore money credited x months
=350 + 87 x
Now to calculate the nearest month when Gina have more in her account than Rodger does
=Amount of money credited in x months in Gina’s account ≥ Amount of money credited in x months in Rodger’s account
=250+124 x ≥ 350+87 x
=37 x≥100
= x≥2.78
=3
Answer:
X=2
Step-by-step explanation:
20x+40=80
20x+40-(80)=0
20x-40=0 20x=40
x=40/20
X=2
Answer:
216
Step-by-step explanation:
Plug in 1 to f(x). 2(1) + 4 = 6
Plug that answer in to h(x).
6^3 = 6*6*6 = 216
X=15. This is the Altitude theorem which is Altitude/Part = Altitude/Other part. In this question you would set up the proportion 9/X = X/25 and multiply cross products to get 225=X^2. Then you undo X^2 by doing the square route of 225 and then you get 15 as the final answer.
