What is the value of x in the equation 1.5(x + 4) – 3 = 4.5(x – 2)?
Step-by-step explanation:
1.5x + 6-3= 4.5x- 2
1.5x+3=4.5x-2
we transposed
4.5x-1.5x= 3+2
3x= 5
we divide both sides by 3
3x/3= 5/3
x= 5/3
True or false? Multiplying a number by itself creates as “perfect square”.
Answer:
true
Step-by-step explanation:
In your own words, describe how you would use construction tools to construct a perpendicular to a line. Explain as if you were teaching a
Geometry newbie. Use vocabulary in your explanation. Give an example of how you could then prove the line you created was
perpendicular to the original line.
Answer:
bisecting line BC
with center B and any radius greater than half of line BC , make arcs below and above line BC with the same radius and C as the center , make. an arc to intersect the first arcs above and below line BC .Name the point where the arc meet , E and F .join EF meet BC as YAn ostrich was 960meters east of its nest. It ran west at a constant velocity for 160seconds. In that time, it ran halfway to its nest. What was its velocity?
Answer is 3 m/s.
Step-by-step explanation:-The ostrich ran at a constant velocity, so it's velocity was :
[tex]velocity = \frac{distance}{time} [/tex]
It is said that the bird ran for 160 seconds and it made it half-way to its nest, so the distance was :
[tex]distance = \frac{960 \: metres}{time} [/tex]
[tex]distance = 480 \: metres[/tex]
And the velocity is :-
[tex]velocity = \frac{480 \: metres}{160 \: seconds} [/tex]
[tex]velocity = 3 \: m/s[/tex]
Therefore, the ostrich ran at a velocity of 3 m/s .
Evaluate for z
11 + 3/5z = 38
Answer:
45
Step-by-step explanation:
Combine 3/5 and z
Move all terms not containing z to the right side of the equation.
3z/5=27
Multiply both sides of the equation by 5/3
Simplify both sides of the equation.
z=45
Find two consecutive even integers such
that 5 times the smaller integer is 44 more
than 2 times the larger integer.
Step-by-step explanation:
5n = 44 + 2(n+2)
5n = 44 +2n+4
5n-2n = 48
3n = 48
n = 16
the integers are : 16 and 18
4) Allison practices her violin for at least 12 hours per week. She practices for three fourths of an hour each
session. If Allison has already practiced 3 hours this week, how many more sessions remain for her to meet
or exceed her weekly practice goal?
Answer:
12
Step-by-step explanation:
So, she practices 12 hrs per week, and already has practiced 3 hrs this week.
This means she has 9 hrs left to practice.
3/4 of an hour is one session, so to find out the number of sessions she needs, you have to do (9 hours)/(one session)
which is basically 9 / ( 3/4)
[tex]\frac{9}{3/4}=\frac{9}{1} / \frac{3}{4} = \frac{9}{1} * \frac{4}{3} = \frac{36}{3} = 12[/tex]
She needs 12 more sessions.
You save $35 a week for a year. How much do you have at the
end of the year? (Hint: Use 52 weeks

Hello NiX010101!
[tex] \huge \boxed{\mathfrak{Question} \downarrow}[/tex]
Solve : [tex]\frac{ 3x-2 }{ 4 } - \frac{ 2x+3 }{ 3 } = \frac{ 2 }{ 3 } -x\\[/tex]
[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
[tex]\frac{ 3x-2 }{ 4 } - \frac{ 2x+3 }{ 3 } = \frac{ 2 }{ 3 } -x \\ [/tex]
Multiply both the sides by the LCM of 4, 3 which is 12. After some simplification you'll get it as ..
[tex]3\left(3x-2\right)-4\left(2x+3\right)=8-12x [/tex]
Now, use the distributive property to open the brackets.
[tex]3\left(3x-2\right)-4\left(2x+3\right)=8-12x \\ 9x - 6 - 8x - 12 = 8 - 12x[/tex]
Now, bring the like terms together & simplify it.
[tex]9x - 6 - 8x - 12 = 8 - 12x \\ 9x - 8x - 6 - 12 = 8 - 12x \\ x - 18 = 8 - 12x \\ x + 12x = 8 + 18 \\ 13x = 26 \\ x = \frac{26}{13} \\ \large \boxed{\boxed{ \bf x = 2}}[/tex]
We got the value of x as 2.

what is 5x(2x+7)+x(3x-5 do you know
Answer:
43xx
Step-by-step explanation:
5x(2x+7)+x(3x-5)
first, do the equations inside the parentheses
2x+7=9x
3x-5=-2x
so,
5x(9x)+x(-2x)
Next, do 5x times 9x
(5x) x (9x) = 45
so,
45+x(-2x)
Next, do x times (-2x)
(x) x (-2x)=-2xx
so,
45+-2xx
=43xx

QUADRATIC EQUATION â€" WORD PROBLEMS
The sum of two numbers is 5 and their product is â’84. Find these numbers
The answer is 12 , -7
I just need the steps
Answer: -7, 12
Step-by-step explanation:
a+b = 5
a*b = -84
a = 5-b
(5-b)*b = -84
-b^2 + 5b + 84 = 0
(-b - 7)(b + 12) = 0
The roots are -7 and 12.

Jen ran directly toward school at a constant velocity for 36 seconds. In one-third of that time, she ran 120 meters. What was her velocity?
Answer is 10 m/s
Step-by-step explanation:-First, we need to calculate one-third of 36 seconds :
[tex] \frac{1}{3} \times 36[/tex]
[tex] \frac{36}{3} [/tex]
[tex]12[/tex]
Now, to find velocity, let's divide the distance by time :
[tex]velocity = \frac{distance}{time} [/tex]
[tex]velocity = \frac{120}{12} [/tex]
[tex]velocity = 10 \: m/s[/tex]
Therefore, Jen's velocity is 10 m/s .

16. For any two integers a and b, (a + b)2 = a² + b2
true or false
Answer:
false is the answer ........
Solution:
(a+b)^2 = (a+b)(a+b)= a^2 + ab + ab + b^2= a^2 + 2ab + b^2So the statement is false and the correct statement is:
For any two integers a and b, (a+b)^2 = a^2+2ab+b^2.
