Answer:
the correct answer is d
Step-by-step explanation:
the answer is d because most of the time when you take an eqation like -4(x-2)+5x and you flip some of the signs it changes the outcome
so x changes the eqation then when you siplify both sides you get
x+8
and
x
so x+8=x that has no solution to the eqation
all of the others come out to x+8 and the will all create infininte solutions other than d
The expression can be written on the other side of the equation is x+8.
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
The given expression is -4(x-2)+5x.
Here, the expression can be simplified as
-4(x-2)+5x
= -4x+8+5x
= x+8
Hence, the expression can be written on the other side of the equation is x+8.

Mark dropped an object from a bridge 400 feet above the ground level with an initial velocity of 0. He knows that the gravitational pull of the earth is about 16 feet per second squared. wants to find how many seconds,t, it will take the object to hit the ground. Match each expression with the correct equation that models this situation or solution.
Answer:
The first listed equation is the correct equation to solve
The correct answer is: t = 5 seconds
Step-by-step explanation:
Let me mention first that there is an error in the statement that the gravitational pull of the Earth is 16 ft/s^2. It is in fact 32 ft/s^2, and the actual equation uses half of the acceleration multiplied by the square of the variable time, so it gives as final expression :
[tex]y(t)=-16\,t^2+ 0 \,t +400[/tex]
and we want to find the value/s for "t" that make this equation equal zero (when it reaches the ground and the object just touches the ground. This makes the equation we want to solve:
[tex]0=-16\,t^2+ 0 \,t +400\\16\,t^2+0\,t -400=0[/tex]
which solving for "t" becomes:
[tex]16\,t^2-400 =0\\16\,t^2=400\\t^2=\frac{400}{16} \\t^2=25\\t= +/- 5\,\,sec[/tex]
So we adopt the positive answer (positive time) since the negative value has no physical meaning for this problem.
That is: t = 5 seconds
correct equation: -16t^2 + 0t + 400 = 0
solution: 5 seconds

Find the area of a circle with diameter 10cm use the value 3.14
Answer:
78.5 cm
Step-by-step explanation:
The area of a circle is represented by A = πr². Since we are replacing the value of pi(π) with 3.14, and the diameter is 10, meaning the radius(r) is 5, we can plug both values into the equation, to get A = 3.14(5^2). This simplifies to 78.5.

In circle P, diameter QS measures 20 centimeters. Circle P is shown. Line segment Q S is a diameter. Line segment R P is a radius. Angle R P S is 123 degrees. What is the approximate length of arc QR? Round to the nearest tenth of a centimeter. 9.9 centimeters 19.9 centimeters 21.5 centimeters 43.0 centimeters
Answer:
Length of arc QR is [tex]\approx[/tex] 9.9 cm
Step-by-step explanation:
Given that circle P, i.e. center is point P.
QS is diameter with length 20 cm.
Given that RP is the radius with
[tex]\angle RPS = 123^\circ[/tex]
To find length of arc QR = ?
Solution:
Arc QR subtends the [tex]\angle QPR[/tex] on center P.
So, we need to find the angle [tex]\angle QPR[/tex] to find the length of arc QR.
QS is the diameter so [tex]\angle QPS = 180^\circ[/tex]
[tex]\angle QPS = 180^\circ = \angle QPR +\angle RPS\\\Rightarrow 180^\circ = \angle QPR +123^\circ\\\Rightarrow \angle QPR = 57^\circ[/tex]
Converting in radians,
[tex]\angle QPR = 57^\circ \times \dfrac{\pi}{180} = 0.99\ radians[/tex]
Using the formula for length of arc:
[tex]l = \theta \times R[/tex]
Where [tex]\theta[/tex] is the angle subtended by the arc on center.
R is the radius of circle.
Here,
[tex]\theta = 0.99\ radians\\R = 10\ cm[/tex]
[tex]l = 0.99 \times 10\\l = 9.9\ cm[/tex]
Length of arc QR is [tex]\approx[/tex] 9.9 cm
Answer:

In the problem RSM × RS × R=2030 each letter stands for a different digit. Find the 3-digit number RSM. Please answer soon!
Answer:
145
Step-by-step explanation:
Answer: R S M = 145
It seems that someone already gave the correct answer for this, but I'll add an explanation in case you're curious!
1. So, we can write it out as:
R S M
R S (make sure you don't simplify it
x R as R^3*S^2*M, as each letter here
---------- stands for an individual digit in a number)
2030
2. The only possible value of R is 1, because any other value would be too big. (For example, 213*21*2=8946), for the sake of simplicity so let's write it as:
R S M
x R S
----------
2030
3. Notice how the last digit in 2030 is 0? That means either M or S =5.
5*2 has a last digit of 0, so let's try that out. Let's sub it in to get 125*12=1500. That's too small, so let's try again.
5*4 also has a last digit of 0. Let's plug that in: 145*14=2030. Yay!
4. In conclusion, RSM*RS*R --- > 145*14*1=2030, so RSM = 145
Hope this helped you :)

And, Triangle DEF is a right triangle,
What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
We have to given that;
Triangle DEF has a 90° angle at vertex E.
Since, In triangle DEF,
vertex E has 90 degree.
So, Possible value of angle E and F are less than 90 degree

Clara is building a triangular garden. She wants the length of the longest side to be three more than twice as long as the length of the shortest side, and the third side will be twelve feet long.
Answer:
3s+15
Step-by-step explanation:
let 's' be the length of the shortest side
-> twice as long as the length of the shortest side =2s
->length of the longest side to be three more than twice as long as the length of the shortest side = 2s + 3
-> the third side= 12 feet
p = s + 12 + 2s+3

Answer:
n is equal to 17 if you want you can plug the number to both equation and try to see if both are equal if they are equal that means you did it right
Answer:
n = 17
Step-by-step explanation:
The opposite angles of a Parallelogram are equal.
So,
4n-2 = 2n+32
4n-2n = 32+2
2n = 34
Dividing both sides by 2
n = 17
