To the nearest hundredth, which is the value of x in the solution of the following system? 3.5x - 2.8 = -4.67x + 12.5 Select one: a. -3.75 b. -1.87 c. 1.87 d. 3.75
Answer:
C. 1.87
Step-by-step explanation:
3.5x - 2.8 = -4.67x + 12.5
3.5x + 4.67x = 12.5 + 2.5
8.17x = 15.3
x = 15.3 ÷ 8.17
x = 1.87270501836
So, the closest choice to 1.87270501836 is 1.87, so the answer is C.
Hence, the answer would be C. 1.87. I am 100% sure on this, for I am a pro.

2. y is inversely proportional to cube of x.
When x = 2, y = 4.
Find y when x = 4
(3 Points)
Answer:
y = 0.5 at x = 4
Step-by-step explanation:
According to question,
y is inversely proportional to cube of x i.e.
[tex]y\propto \dfrac{1}{x^3}\\\\y=\dfrac{k}{x^3}[/tex]
or
[tex]k=yx^3[/tex]
Put x = 2 and y = 4 in above expression to find k.
[tex]k=4\times (2)^3\\\\=32[/tex]
Now put x = 4 to given equation to find y.
[tex]y=\dfrac{32}{4^3}[/tex]
y = 0.5 or 1/2
So, the value of y is 0.5 when x = 4.

Answer:
B. <
Step-by-step explanation:
The whole parts are equal since they are both 9.
We just need to compare the fractions 3/8 and 5/7.
The LCD is 8 * 7 = 56
3/8 = 21/56
5/7 = 40/56
3/8 < 5/7

Answer:
8 grams
Step-by-step explanation:
The balance is in equilibrium, so the weights of the two sides are equal.
Let the weight of a square be s.
Left side: 2s + 4
Right side: s + 3(4) = s + 12
The weights are equal, so we set the two expressions equal.
2s + 4 = s + 12
s = 8
Answer: The weight of a square is 8 grams.
Question 2: The first step was the combine the like terms; in this example he is subtracting the 3x on both sides of the =.
Answer: x=14
only #2
Step-by-step explanation:
Step 1: Subtract 3x from both sides.
2x+6−3x=3x−8−3x
−x+6=−8
Step 2: Subtract 6 from both sides.
−x+6−6=−8−6
−x=−14
Step 3: Divide both sides by -1.
-x/-1=-14/-1

Answer:
A. 7 divided by 2
Step-by-step explanation:
The computation is shown below;
[tex]= 6\frac{3}{4} \div 1 \frac{2}{3} \\\\= \frac{27}{4} \div \frac{5}{3}\\\\= \frac{27}{4} \times \frac{3}{5}\\\\= \frac{27\times 3}{4\times 5} \\\\= \frac{81}{20} \\\\= 4 \frac{1}{20}[/tex]

Step-by-step explanation:
hope this helps!
Answer:
x=0, y=2. (0, 2).
Step-by-step explanation:
y=12x+2
2y=x+4
------------
2(12x+2)=x+4
24x+4=x+4
24x-x=4-4
23x=0
x=0/23
x=0
y=12(0)+2
y=0+2
y=2

(3,1) and (w,9); slope = -8/3
W= ?
Answer:
w=0
Step-by-step explanation:
We know a point (3,1) and the slope (-8/3), so we can use point-slope form, which is y-y1=m(x-x1)
For reference, y1 is the y in the point, m is the slope, and x1 is the x in the point
So we subsitute it
y-1=-8/3(x-3)
do distributive prop.
y-1=-8/3x+8
add 1 to both sides
y=-8/3x+9
This is the equation of the line.
Now to find w, which is the x value.
The point will pass through line, so we can susbtitute the point into the equation.
9=-8/3x+9
subtract 9 from both sides
0=-8/3x
multiply by -3/8 on both sides (the reciprocal of -8/3), we need to isolate x
0=x
x=w
therefore, w=0
Hope this helps!
help please !!
don’t understand
Step-by-step explanation:
For two lines to be parallel they must have the same slope that is,M1=M2
For two lines to be perpendicular the slope of one must be the negative reciprocal of the other
Let's first find the slope of all three lines.
For line 1
6x-6=10y
2/5x-2/5=y
slope=2/5
For like 2
slope=5/3
For line 3
y=5/3x+2/3
We can therefore say that:
line 1 and line2 are neither parallel nor perpendicular
line 1 and line 3:
neither parallel nor perpendicular
line 2and line 3:
parallel lines
The shadow of a vertical tower is 52.5 meters long when the angle of elevation of the sun is x degrees. The height of the tower is 41 meters. Find the angle of elevation rounded to the nearest degree.
Answer:
Angle of Elevation = 38°
Step-by-step explanation:
Angle of Elevation formula is given as
tan x = Opposite /Adjacent
Where
x = Angle of Elevation
Opposite = Height of the tower = 41 meters
Adjacent = Shadow of the vertical tower = 52.5 meters
Hence:
tan x = 41 m/52.5m
x = arc tan (41 m/52.5m)
x = 37.988141726°
Approximately to the nearest degree x = 38°
