Step-by-step explanation:
Let's solve your equation step-by-step.
2x−4=2(x−2)
Step 1: Simplify both sides of the equation.
2x−4=2(x−2)
2x+−4=(2)(x)+(2)(−2)(Distribute)
2x+−4=2x+−4
2x−4=2x−4
Step 2: Subtract 2x from both sides.
2x−4−2x=2x−4−2x
−4=−4
Step 3: Add 4 to both sides.
−4+4=−4+4

Given that r is directly proportional to
y and inversely proportional to Z,
x= 15 when y = 10 and Z= 4, find
the equation connecting x, y and Z.
Answers
Given:
x is directly proportional to y and inversely proportional to z.
x= 15 when y = 10 and z= 4.
To find:
The equation that connecting x, y and z.
Solution:
It is given that, x is directly proportional to y and inversely proportional to z.
[tex]x\propto \dfrac{y}{z}[/tex]
[tex]x=\dfrac{ky}{z}[/tex] ...(i)
Where, k is the constant of proportionality.
We have, x= 15 when y = 10 and z= 4.
[tex]15=\dfrac{k(10)}{4}[/tex]
[tex]15\times 4=10k[/tex]
[tex]60=10k[/tex]
Divide both sides by 10.
[tex]\dfrac{60}{10}=k[/tex]
[tex]6=k[/tex]
Putting k=6 in (i), we get
[tex]x=\dfrac{6y}{z}[/tex]
Therefore, the required equation is [tex]x=\dfrac{6y}{z}[/tex].
A rectangle has an area of 170.2m2
One of the sides is 3.7m in length.
Work out the perimeter of the rectangle.
Answers
Answer:
here
Area = 170.2 M2
Area of rectangle = l *b
let l= 3.7m
170.2 = 3.7* b
b= 46m
now , perimeter = 2(l+b)
= 2( 3.7 + 46)
= 99.4 m

Step-by-step explanation:
7x2=14
16x1/2=8
14-8=6
6+5=11
The evaluation of the given equation when the a is 0.5 and b = 7 so it should be considered as the 46.
Evaluation of the given equation;Since the equation is
[tex]b^2 - 16a + 5[/tex]
So,
