D.
Let, x= number of $2 increase in price and y= revenue.
So, we are given the data,
x y
1 1045
3 1105
5 1125
7 1105
9 1045
So, using the regression calculator, we get that,
Answer:
see explanation
Step-by-step explanation:
x + y = 90 → (1) ( complementary angles )
x + z = 180 → (2) ( supplementary angles ) and
z = 3x - 8 ( 8 less than 3 times x ), substituting in (2)
x + 3x - 8 = 180
4x - 8 = 180 ( add 8 to both sides )
4x = 188 ( divide both sides by 4 )
x = 47
Substitute x = 47 into (1)
47 + y = 90 ( subtract 47 from both sides )
y = 43
and z = 3x - 8 = 3(47) - 8 = 141 - 8 = 133
Thus
x = 47°, y = 43° and z = 133°
Answer:
![\boxed{\sf{4(5x+3y-7)}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Csf%7B4%285x%2B3y-7%29%7D%7D)
Step-by-step explanation:
It is necessary to find the factors and solve them using their expressions in order to solve this problem.
<h3>20x+12y-28</h3>
7*4=28
3*4=12
5*4=20
Rewrite the problem down.
5*4x+3*4y+7*4
Solve.
Common term of 4.
<u>4(5x+3y-7)</u>
- <u>Therefore, the final answer is 4(5x+3y-7).</u>

Answer:
I'm fairly sure its 4.93 grams.
Step-by-step explanation:
you take the origional water of 45.1ml and the new 52.3ml, and find the difference, which in this case is 7.2ml.
the density formula is D=M/V
D= Density
M=Mass
V=Volume
so it would be
D= 35.49/7.2
which is 4.93.
again this is just from what I remember of science class.
