(5x + 10) / (x + 2) * 2x / (4x - 10)
= 5(x + 2) / (x + 2) * 2x / 2 (2x - 5)
= 5 *2 = 2x / (2x - 5)
= 10 * (2x - 5) = 2x
= 20x - 50 = 2x
= 20x - 2x = 50
= x = 50 / 18
In short, Your Answer would be 25/9
Hope this helps!
So to start off on answering we are going to s<span>ubtract 3/5 from both of the sides:
</span><span><span><span><span><span>−1/</span>2</span>u</span>+<span>3/5</span></span>−3/5</span>=<span><span>1/6</span>−<span>3/<span>5
</span></span></span><span><span><span>−1/</span>2</span>u</span>=<span><span>−13/</span><span>30
Okay, so now we are going to mu</span></span><span>ltiply both sides by 2/(-1):
</span><span><span>(<span>2/<span>−1</span></span>)</span>*<span>(<span><span><span>−1/</span>2</span>u</span>)</span></span>=<span><span>(<span>2/<span>−1</span></span>)</span>*<span>(<span><span>−13/</span>30</span><span>)
</span></span></span>The final answer shall be:
u=<span>13/<span>15
I hope this helps! </span></span>
The correct question in the attached figure
case A) an=2<span>^(n-1)
for n=8
a8=2</span>^(8-1)-----> a8=2<span>^7----> a8=128
the answer case A) is a8=128case B) an=7
then for n=8
a8=7
the answer case B) isa8=7case C) an=1+(-1)</span><span>^n
for n=8
a8=1+(-1)</span><span>^8----> a8=1+1----> a8=2
the answer case C) isa8=2case D)an=-(-2)</span><span>^n
for n=8
a8=-(-2)</span><span>^8----> a8=-256
the answer case D) isa8=-256</span>
To solve this, we need to use the z statistic. The formula for z score is:
z = (x – u) / s
where x is sample value = less than 90, u is the sample mean = 90.6, s is the standard deviation = 17.2
z = (90 – 90.6) / 17.2
z = -0.035
From the standard distribution tables:
P (z = -0.035) = 0.4860
Therefore there is about 48.60 % chance that it will be less than 90 pounds
9x - 5y = 29....when x = 1
9(1) - 5y = 29
9 - 5y = 29
-5y = 29 - 9
-5y = 20
y = 20/-5
y = -4 <==
