We are given that Jack and Jillian sell apples at a produce stand .
We are given that an expression which shows Jack's earning=2x-8
We have to find that first term what represent in the given expression
Jillian earns for each bag of apples she sells=$2
Let Jillian sold number of bags of apples =x
Then ,Jillian earn total at the end of the week =
Jack has earned $ 8 less than Jillian earn
Therefore, total earning of jack=
In the given expression the first term 2x represent the earning of Jillian.
<span>sinx - cosx =sqrt(2)
Taking square on both sides:
</span>(sinx - cosx)^2 =sqrt(2)^2<span>
sin^2(x) -2cos(x)sin(x) + cos^2(x) = 2
Rearranging the equation:
sin^2(x)+cos^2(x) -2cos(x)sin(x)=2
As,
</span><span>sin^2(x)+cos^2(x) = 1
</span><span>So,
1-2sinxcosx=2
1-1-2sinxcosx=2-1
-</span><span>2sinxcosx = 1
</span><span>Using Trignometric identities:
-2(0.5(sin(x+x)+sin(x-x))=1
-sin2x+sin0=1
As,
sin 0 = 0
So,
sin2x+0 = -1
</span><span>sin2x = -1</span><span>
2x=-90 degrees + t360
Dividing by 2 on both sides:
x=-45 degrees + t180
or 2x=270 degrees +t360
x= 135 degrees + t180 where t is integer</span>
Answer:
![\sqrt[3]{5x+10}=5 / ^{3}\\ 5x+10=125\\5x=115/:5\\x=23](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B5x%2B10%7D%3D5%20%2F%20%5E%7B3%7D%5C%5C%20%205x%2B10%3D125%5C%5C5x%3D115%2F%3A5%5C%5Cx%3D23)
If you mean that :![\sqrt[3]{5x}+10=5](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B5x%7D%2B10%3D5)
this is
![\sqrt[3]{5x}+10=5 /^{3} \\5x+1000=125\\5x=-875/:5\\x=-175](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B5x%7D%2B10%3D5%20%2F%5E%7B3%7D%20%5C%5C5x%2B1000%3D125%5C%5C5x%3D-875%2F%3A5%5C%5Cx%3D-175)
Step-by-step explanation:
Answer:
x=6
Step-by-step explanation:
Step 1: Subtract 4x from both sides.
5x−3−4x=4x+3−4x
x−3=3
Step 2: Add 3 to both sides.
x−3+3=3+3
x=6
