What real value or values of x satisfy the equation x−2=√x
Answer:
[tex]x=1,\:x=4[/tex]
Step-by-step explanation:
[tex]x-2=\sqrt{x}\\\\(x-2)^2=x\\\\x^2-4x+4=x\\\\x^2-5x+4=0\\\\(x-1)(x-4)=0\\\\x=1,\:x=4[/tex]
x=1 and x=4 are real value or values of x satisfy the equation x−2=√x
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
Equation is x−2=√x
We need to find for which values of x satisfy the equation.
x−2=√x
Take square on both the sides
(x-2)²=√x²
We know the algebraic identity
(a-b)²=a²+b²-2ab
(x-2)²=√x²
x²+2²-2(2)x=x
x²+4-4x=x
x²+4-4x-x=0
x²-5x+4=0
x²-4x-x+4=0
x(x-4)-(x-4)=0
(x-1)(x-4)=0
x-1=0
x=1
x-4=0
x=4
Hence, x=1 and x=4 are real value or values of x satisfy the equation x−2=√x

Which step could be used to help isolate the variable in the following equation? 5. 6j – 0. 12 = 4 1. 1j.
For the expression 5.6j - 0.12 = 4 + 1.1j, the value of variable j is 0.92.
What is the property of equality?
The operations of addition, subtraction, multiplication, and division do not change the truth value of any equation is called the property of equality.
The given expression is 5.6j - 0.12 = 4 + 1.1j.
To solve the above expression, we will use the following steps.
Step 1:
By the subtraction property of equality, subtract 1.1j on both sides. We get the expression,
[tex]5.6j - 0.12 -1.1j = 4 + 1.1 j - 1.1 j[/tex]
[tex]4.5 j -0.12 = 4[/tex]
Step 2:
By the addition property of equality, add 0.12 on both sides. We get the expression,
[tex]4.5j -0.12 + 0.12 = 4 + 0.12[/tex]
[tex]4.5 j = 4.12[/tex]
Step 3:
By the division property of equality, divide the above expression by 4.5. We get the expression,
[tex]\dfrac {4.5j}{4.5 }= \dfrac {4.12}{4.5}[/tex]
[tex]j = \dfrac {4.12}{4.5}[/tex]
[tex]j = 0.92[/tex]
Hence we can conclude that the value of variable j is 0.92.

Gina bought x cans of peas for $0.85 each and yvcans of corn for $0.78 each. She boguth 2 more cans of peas than cans of corn. The total was $6.59. How many cans of oeas and cans of corn dis she buy?
I ONLY NEED THE EQUATION...I can get the numbers of cans and peas I just need the equations to find the numbers
This is Algebra....please help me!!
Answer:
Step-by-step explanation:
Number of cans of peas = x
Cost of 'x' cans of peas = x *0.85 = 0.85x
Number of cans of corn = y
Cost of 'y' cans of corn = 0.78*y = 0.78y
Number of cans of peas = number of cans of corn + 2
x = y + 2 --------------(I)
x - y = 2 ----------------(II)
Total cost = $ 6.59
0.85x + 0.78y = 6.59 -------------(III)
Substitute x = y +2 in equation (III)
0.85(y + 2) + 0.78y = 6.59
0.85y + 1.70 + 0.78y = 6.59
0.85y + 0.78y = 6.59- 1.70
1.63y = 4.89
y = 4.89/1.63
y = 3
Number of cans of corn = 3
Plugin y = 3 in equation (I)
x = 3 + 2
x = 5
Number of cans of peas = 5

The stock of Company A gained 3.5% today to $16.56 . What was the opening price of the stock in the beginning of the day?
well, the opening price was "x", which oddly enough is the 100%, however during the trading of the day the company gained 3.5%, so that'd be 100% + 3.5% = 103.5%, and we know that that is 16.56, so
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} x&100\\ 16.56&103.5 \end{array}\implies \cfrac{x}{16.56}=\cfrac{100}{103.5}\implies 103.5x=1656 \\\\\\ x=\cfrac{1656}{103.5}\implies x=16[/tex]

Step-by-step explanation:
The figure is a parallelogram.
Consecutive angles are supplementary ( sum to 180° ) , then
x + 65° = 180 ( subtract 65° from both sides )
x = 115°
Opposite angles are congruent , then
y = 65°

Step-by-step explanation:
Answer:
D. 60°
Step-by-step explanation:
The interior angles of all triangles add up to 180 degrees.
There are two y's on the triangle
And one of the degree lengths is 60°, so we do:
2y + 60 = 180
Subtract 60 from both sides
2y + 60 - 60 = 180 - 60
2y = 120
Divide 2 from both sides
2y/2 = 120/2
y = 60°
Also, In geometry, an equilateral triangle is a triangle in which all three sides have the same length. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.
All three sides are equal
All the three interior angles are equal to 60 degrees
The interior angles of all triangles add up to 180 degrees.
Heres a picture of an equilateral triangle
What is the percentage of lemons in the is group of lemons and strawberries?
Answer:
70%
Step-by-step explanation:
Total: 60
Strawberries: 18
Lemons: 42
[tex]\frac{42}{60}[/tex] = [tex]\frac{7}{10}[/tex] = 70%
The percentage of lemons in the group is equal to 70%.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that in the image there are 60 objects in total, the number of lemons is 42 and the number of strawberries is 18.
Total: 60
Strawberries: 18
Lemons: 42
The percentage of the lemons will be calculated as,
Percentage = 42 / 60
Percentage = 0.7
Percentage = 0.7 x 100 = 70%
Therefore, the percentage of lemons in the group is equal to 70%.

Step-by-step explanation:
Given,GRAM is a parallelogram m<GMA = 66°m<GRP = 32°m<PAM = 41°Solutions:i) Since,
Angles on the same side of a transversal in a parallelogram, there sum is 180° so,
<RGM + <GMA = 180°
=> <RGM = 180° - <GMA
=> <RGM = 180° - 66°
=> <RGM = 114° (Ans)
ii) Since,
Opposite angles of a diagonal as a transversal (here RM) are equal so,
<GRP = <PMA = 32°
As we have <GMA = 66° so,
=> <GMP = <GMA - <PMA
= 66° - 32°
=> <GMP = 34° (Ans)
iii) Since,
Opposite angles of a parallelogram are equal so,
<RGM = <RAM = 114°
As we have <PAM = 41° so,
=> <GAR = <RAM - <PAM
= 114° - 41°
=> <GAR = 73° (Ans)
iv) Since,
We got <PMA = 32° and <PAM = 41°, so by angle sum property of a triangle PMA,
=> <MPA = 180° - 32° - 41°
=> <MPA = 107° (Ans)
