I Keep Getting The Answer Wrong For The Value Please Help.

Answers

Answer 1

Answer: d) +/- 2/3

Step-by-step explanation: Since x^2 is a exponent, to cancel it out you would have to square root both sides. Therefore, x is equal to +/- 2/3.

Answer 2

Answer:

D

Step-by-step explanation:

The answer is D which is ± 2/3.

x² = 36/81

The √36 is 6 and √81 is 9. So √(36/81) will be 2/3. However, the answer is ±2/3 because we are taking the square root so there's a possibility that the answer can be positive and negative.

Tory and her friend Terrence ride their bikes to school each day. On one particular day, Tory started out 5 minutes before Terrence. Tory rides at a rate of 880 feet per minute and Terrence rides at a rate of 1.056 feet per minut
How long had Tory been riding when Terrence caught up with her?

Answers

Answer:

4:30 minutes im thinking

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.

What is meant by 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

7) Joey is four years older than Billy. The sum of
their ages is 24.
a) Write a system of equations to represent
this situation. Let j=Joey's age and
b=Billy's age.
b) Solve to determine the age of both Billy and
Joey

Answers

Answer:

Joey is 14, Billy is 10.

Step-by-step explanation:

The system of equations you can use is:

j=b+4

j+b=24

(b+4)+b=24

2b+4=24

2b=20

b=10

j=10+4

j=14

Answer: j+b=24

J=b+4

Step-by-step explanation: (b+4) + b=24

You’re going to substitue J=b+4 into j+b=24

you’re going to get joeys age 14, Billy’s age 10

20r + 11r + –19r − –4 = –20

Answers

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

to get the midpoint of two endpoints, simply take the average of each corresponding coordinate

midpoint: ((Rx+Sx)/2,(Ry+Sy/2)).

((9+2/2),(-4+-8/2)) = (11/2,-12/2) = (11/2,-6)

the midpoint formula in general is : ((x+x1)/2),(y+y1)/2))
