Answer: 4

Step-by-step explanation:

I think the answers correct because, If they give us pactricia's age and it's 23, then we have to subtracct 7 and divide by 4. First of all 23 minuts 7 equals 16, then we divide 16 by 4 and that equals 4 and you got your answer.

Hope This Helps!

Answer:

4

Step-by-step explanation:

We need to break the problems down into smaller parts.

First, what do we need to find. Audrey's age!. Consider it this box □ where we can write her age in later.

Now we move to the difficult part: "Because Four times Audrey's age plus 7 is Patricia age"; we can change it to four times Audrey's age is 23, because Patricia is 23.

Now Audrey age is □, so four times □ plus 7 is 23.

From this, we can replace words by numbers and operations like +,×,÷,=,...

4×□ +7=23

because the two sides of the = is equal, the two sides would still be equal if we remove the same amount

4×□ +7 -7= 23-7

then

4×□+(7-7)=16

then

4×□+0=16

then

4×□=16

then we find the best number to fit is 4.

That's how we find Audrey's age

Solve the system by graphing. Select the solution(s).<br> y = x + 2<br> y = 0.5(x + 2)
faltersainse [42]

Answer:

Part 1) The solution is the point (-2,0)

Part 2) The solutions are the points (-2,0) and (0,2)

Step-by-step explanation:

Part 1

we have

y=x+2 -----> equation A

y=0.5(x+2) ----> y=0.5x+1 ---> equation B

Solve the system by graphing

Remember that the solution of the system is the intersection point both graphs

using a graphing tool

The solution is the point (-2,0)

see the attached figure N 1

Part 2

we have

y=x+2 -----> equation A

y=0.5(x+2)^2 ----> equation B

Solve the system by graphing

Remember that the solution of the system are the intersection points both graphs

using a graphing tool

The solutions are the points (-2,0) and (0,2)

see the attached figure N 2

What is the value of x?<br> Enter your answer in the box.<br> x =
olasank [31]

Answer:

x = 21

Step-by-step explanation:

The sum the the interior angles of a triangle is 180°.

We know that the three angles of the triangle is 100°, x° - 4, and 3x°.

The sum of 100°, x° - 4, and 3x° must equal 180°. We can turn this into the equation:

100 + x - 4 + 3x = 180

(I got rid of the degree signs because they are not necessary when finding x.)

Now, to find the value of x, we would have to solve for x in the equation 100 + x - 4 + 3x = 180.

100 + x - 4 + 3x = 180

Subtract 100 from both sides to get rid of the 100 on the left side.

x - 4 + 3x = 180 - 100

Simplify.

x - 4 + 3x = 80

Add 4 from both sides to get rid of the -4 on the left side.

x + 3x = 80 + 4

Simplify and combine like terms.

4x = 84

Divide 4 from both sides to get rid of the coefficient of 4 on the left side.

x = 84/4

Simply.

x = 21

The value of x would be 21.

x = 21

I hope you find this helpful. :)
