what's the value for x makes this equation true 3/5 X-0.5=19
Answer:
what's the value for x makes this equation true 3/5 X-0.5=19 HERE YOU GO!!
Step-by-step explanation:
-5x - (-7 - 4x) = -2(3x - 4)
-5x + 7+ 4x = -6x + 8
-x + 7= -6x + 8
5x = 8 - 7
5x = 1
x = 1/5
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
The value of x that makes the equation 3/5x - 0.5 = 19 true is 32.5.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x = 4 is an equation.
3x = 6 + 5 is an equation.
We have,
3/5x - 0.5 = 19
Add 0.5 on both sides.
3/5x = 19 + 0.5
3/5x = 19.5
Multiply 5/3 on both sides.
x = 19.5 x 5/3
x = 32.5
Thus,
The value of x that makes the equation 3/5x - 0.5 = 19 true is 32.5.

Solve each system by using substitution
X= Y - 2 4X + Y = 2
Answer:
10
Step-by-step explanation:
Answer:
(0, 2 )
Step-by-step explanation:
Given the 2 equations
x = y - 2 → (1)
4x + y = 2 → (2)
Substitute x = y - 2 into (2)
4(y - 2) + y = 2
4y - 8 + y = 2
5y - 8 = 2 ( add 8 to both sides )
5y = 10 ( divide both sides by 5 )
y = 2
Substitute y = 2 into (1) for corresponding value of x
x = 2 - 2 = 0
Solution is (0, 2 )

Steve and Brian are both avid bicyclists. Each week, Steve rides for a total of 2x hours at an average speed of x miles per hour.
sBrian rides 6 more hours a week than Steve, but at an average speed that is 4 miles per hour less than Steve's average speed.
Which of the following functions will give the total distance that Brian rides each week, in miles?
Answer:
m(x) = 2x^2 - 2x - 24
Step-by-step explanation:
We will use the speed formula for this.
d/t = s
d is distance
t is time
s is speed
since we are looking for a function that gives the distance, we must rewrite
the equation to have d on one side of the equation by itself. We will do this by multiplying both sides by t.
(d/t)t = (s)t
which simplifies to:
d = st
Now we must find out what s and t are.
t: Steve's time riding is 2x hours, and Brian's is 6 more hours, so
Brian's time riding is 2x + 6.
so t = 2x + 6.
s: Steve's speed is x mph. Brian's is 4 less than that so
s = x - 4.
Now we can plug in what we know the the formula we made: d=st
d = (2x + 6)(x-4)
now we can FOIL.
(2x)(x)= 2x^2
(2x)(-4)= -8x
(6)(x) = 6x
(6)(-4) = -24
d = 2x^2 - 8x + 6x - 24
simplify:
Answer: d = 2x^2 -2x - 24

Which statement about the ordered pairs (3, -8) and (4, 4) is true for the equation 3x - y/4 = 11?
A. Neither ordered pair is a solution.
B. Both ordered pairs are solutions.
C. (4, 4) is a solution to the equation but not (3, -8).
D. (3, -8) is a solution to the equation but not (4, 4).
Answer:
Neither ordered pair is a solution.
Step-by-step explanation:
If we substitute an ordered pair which is the correct solution, we will obtain the value at the right hand side of the equation.
Now let us try it;
Substitute (3,-8)
3(3)-(-8)/4 = 9 +8/4 =17/4
Again;
3(4) - 4/4 = 8/4 =2
Hence, none of the ordered pairs is a solution.

Which value of x satisfies the equation |-2x|=10
Answer:
Step-by-step explanation:
First you will divide I-2xI on both sides that should look like this:
-2x/-2 = 10/-2
when you divide it your -2‘s should cancel out and you should be left with
-x=10/-2
when You divide 10/-2 you should get -5
10/-2= -5
your answer should look like this then
-x=-5
-5 is just one of your answers the other is 5
To get rid of the negative on the -X you have to didvide it by both sides
-x/-x=-5/-x
your answer should be
X= 5
your final answers are
-5 or 5
The value of x is "5".
Equation:[tex]|-2x|=10[/tex]
x=?
[tex]\to |-2x|=10\\\\\to 2x=10\\\\\to x=\frac{10}{2}\\\\\to x= 5[/tex]
Therefore, the final answer is "5".

Communities A,B and C are faced with acute water problem. The distance between communities A and B is 5km and that of A and C 7km. The angle between path AB and AC is 45degrees. If a well is dug for the three communities such that it would have equal distance to the path linking each communities. (a) Indicate by a way of sketching the exact place to dig the well? (b) Measure the distance between communities B and C?
Answer:
a) by finding the incentre
b) 5 km
Step-by-step explanation:
Let the communities A, B and C be shown by the three points of the triangle as shown in the figure below. As the angle between the path Ab and Ac is 45 degrees this is an isosceles triangle having two angles equal. As this is an isosceles triangle it must also have two sides equal .
a) the in center point can be used to have equal distance to the path linking each communities.
We take a compass and draw arcs on the two sides of the vertex and placing the compass on the arcs bisect each angle made by the triangles arms.
Joining the bisectors the lines meet at a point which is highlighted by a circle in the diagram.
This is the incentre which is equidistant from each vertex.
b) Using Pythagorus theorem
c² = a² + b²
7²= 5² + b²
b²= 24
b= 4.89= 5 km
The path between B and C is also 5 km.

Step-by-step explanation:
The surface area of a prism is SA= 2lw+2lh+2hw
We are trying to find out the width if the SA is 240 square inches, length is 12 inches, and the height is 5 inches. Let's plug these numbers into the equation.
240=(2*12*w)+(2*12*5)+(2*5*w)
24w+120+10w
240= 34w+120
-120 -120
120= 34w
120/34 = 34w/34
w is approximately equal to 3.5 which can be rounded to 4
w=4

Kenny had a total of 140 minutes to read, do homework, and play video games. he spent x minutes reading. he spent 2(x + 5) minutes doing homework and he spent 25 minutes playing video games. How many minutes did Kenny spent reading?
Answer:
35 min
Step-by-step explanation:
given that the total time spent is 140min
and that the time spent reading is x minutes
and also that the time spent doing home work is 2(x+5)
the time spent playing video game is 25
the expression for the total time is given as
total = reading +homework +video game
140=x+2(x+5)+25
solving for x we have
140=x+2x+10+25
140=3x+35
140-35=3x
105=3x
x=105/3
x=35
kenny spent 35 min reading
Time spend for reading is 35 minutes
Given that;
Total number of minutes Kenny have = 140 minutes
Time spend for reading = x
Time spend for homework = 2(x + 5) = 2x + 10
Time spend for games = 25 minutes
Find:
Time spend for reading
Computation:
Total number of minutes Kenny have = Time spend for reading + Time spend for homework + Time spend for games
140 = x + 2x + 10 + 25
3x + 35 = 140
3x = 105
x = 105 / 3
x = 35
So,
Time spend for reading = 35 minutes
