Explain how to create an equation with infinitely many solutions

Answer:

  [4 over x equals 5 over 10]  

Solve for x, so you need to isolate/get x by itself in the equation.

      Multiply x on both sides

      Multiply the inverse of 5/10, which is 10/5, to get rid of the fraction and get x by itself

8 = x

Answer:

B = 3.75t

Step-by-step explanation:

Given;

initial charge of Arianna's phone = 45%

the charge remaining in Arianna battery = 15%

If after 4hours of leaving her house, the battery had 15% remaining battery life, then the battery is discharging at the rate of ( 15% / 4hours) 3.75% per hour.

Thus, the charge remaining in Arianna's battery after she left her house is given by;

B = 3.75t

where;

t is time in hours

B is the percentage of charge remaining

Step-by-step explanation:

Value of b will be 9

In algebra , a quadratic equation is any equation that can be rearranged in standard form as ax^2 + b x + c =0 where  x represent unknown and a, b and c are constants .

using algebraic functions , solving given equation

-3x^2 + 5x -2 -2x^2 + 4x + 2

-5x^2 + 9x +0                                       equation 1

now , comparing simplified  equation 1 with general quadratic equation (ax^2 +b x +c ), we get

a=-5

b=9

c=0

so, value of b = 9

Answer:

m∠STU is 20°

Step-by-step explanation:

If a ray bisects an angle, then it divides it into two equal angles in measures and the measure of each one is half the measure of this angle

∵ Ray TV bisects ∠STU

→ That means it divides it into two angles STV and UTV

∴ m∠STV = m∠UTV = [tex]\frac{1}{2}[/tex] m∠STU

∵ m∠STV = ([tex]\frac{1}{4}[/tex]x + 8)°

∴ m∠UTV = (x + 2)°

→ Equate them

∴ x + 2 = [tex]\frac{1}{4}[/tex]x + 8

→ Subtract 2 from both sides

∴ x + 2 - 2 =  [tex]\frac{1}{4}[/tex]x + 8 - 2

∴ x =  [tex]\frac{1}{4}[/tex]x + 6

→ Subtract  [tex]\frac{1}{4}[/tex]x from both sides

∴ x -  [tex]\frac{1}{4}[/tex]x =  [tex]\frac{1}{4}[/tex]x -  [tex]\frac{1}{4}[/tex]x + 6

∴  [tex]\frac{3}{4}[/tex]x = 6

→ Divide both sides by  [tex]\frac{3}{4}[/tex] to find x

∴ x = 8

→ Substitute the value of x in the measure of any given angle

∵ m∠UTV = 8 + 2 = 10°

∵ m∠UTV =  [tex]\frac{1}{2}[/tex] m∠STU

∴ 10° =  [tex]\frac{1}{2}[/tex] m∠STU

→ Multiply both sides by 2

∴ 20° = m∠STU

∴ The measure of angle STU is 20°

Answer:

r=-2

Step-by-step explanation:

First, you need to combine like terms so now you have 12r-(-4)=-20. Then you have to subtract -4 to -20 which equals -24 so now you have 12r=-24. Finally, you divide 12 from both sides and you get r=-2

Answer:

r = -2

Step-by-step explanation:

20r + 11r - 19r + 4 = -20

12r + 4 = -20

subtract 4 from both sides of the equation

12r + 4 - 4 = -20 - 4

12r = -24

divide both sides by 12

12r/12 = -24/12

r = -2

Answer: B. 4/5 cups.

Step-by-step explanation:

Ratio number of--> chocolate chips : dozens of cookies made

                           -->               4           :           5

The question ask for 1 dozen of cookies. In the ratio above, it states for 5 dozens of cookies.

Our new ratio would be:

Chocolate chips: dozens of cookies made

                    x     :         1

we turn the 5 in the right side of ratio by dividing by 5 so we must do the same for other side of ratio by dividing 5 with 4.

x=4/5

hence answer is B. 4/5 cups

Step-by-step explanation:

The value is  30 minutes. Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression.

Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the expression 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.

The expression that give us the distance that Tory has ride after t minutes is:

D = 880t

Because Tory rides at 880 feet per minute.

At the same way, the distance that Terrence has ride after t minutes is equal to:

D = 1056(t - 5)

Because Terrence rides at 1056 feet per minute and he starts out 5 minutes after Tory

Now, we need to find t when both expressions are equal, so we can formulate the following equation:

[tex]880t=1056(t-5)[/tex]

So, solving for t, we get:

[tex]880t=1056t - 1056.5[/tex]

[tex]880t=1056t - 5280[/tex]

[tex]880t=1056t =-5280[/tex]

[tex]-176t=-5280[/tex]

[tex]t=-5280/-176[/tex]

[tex]t= 30[/tex]

Therefore the answer is 30 minutes

Answer:

A. One real solution

Step-by-step explanation:

The discriminant is used to find the number of real solutions to a quadratic equation.

If the discriminant is greater than 0, there are two real solutions.

If the discriminant is equal to 0, there is one real solution.

If the discriminant is less than 0, there are no real solutions.

All quadratic equations have the format:

ax^2+bx+c

Therefore our values for a, b and c are the following:

a = 4

b = -12

c = 9

Therefore the discriminant is:

(-12)^2-4(4)(9)

144-144 = 0

The discriminant is equal to 0, so there is one real solution (Option A).

Answer:

4 hours

Step-by-step explanation:

Let the size of  whole wall be x.

Given that

Ralph painted 1/6 of a wall in 2/3 hours

thus, writing it in mathematical form we have,

time taken to pain 1/6 of x = 2/3 hours

=>time taken to pain x/6 wall = 2/3 hours

since, we have taken size as x so to find time to pain x size of wall ,

we divide both side by 6

=>time taken to pain x/6 * 6 wall = 2/3 *6 hours

=> time taken to pain x wall = 4 hours

Thus, It will take 4 hours to paint whole wall
