The answer is x=1.
1x-1= 5x+ 3x- 8
1x-1= 8x-8
-1x -1x
-1=7x-8
+8 +8
7=7x
1=x

I hope this helps love! :)

a. no. both a and b are incorrect.

b. no. the value for b is incorrect.

c. no. the value for a is incorrect.

d. yes. this is the correct equation."

The equation predict for a value of x = 7 in equation y = 2.5x – 1.5 is (x, y) = (3, 16). Option B is correct.

<h3>What is a system of equations?</h3>

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

"A data set consists of the following data points: (2,4),(4,7), (5, 12)

y = 2.5x - 1.5

Puy x = 7

y = 2.5(7) - 1.5

y = 17.5 - 1.5

y = 16

The equation predict for a value of x = 7 in equation y = 2.5x – 1.5 is (x, y) = (3, 16). Option B is correct.

Dion has a pizza with a diameter of 10 1/3 inch is the square box shown big enough to fit the pizza inside justify your answer

I am Lyosha [343]

Given :

Diameter of pizza , $D=10\dfrac{1}{3}=\dfrac{31}{3}$ .

To Find :

Is square box of size equal to diameter big enough to fit pizza inside it .

Solution :

Area of pizza :

$A_p=\pi(\dfrac{D}{2})^2\\\\A_p=\pi\times (\dfrac{31}{3\times 2})^2\\\\A_p=83.86\ inch^2$

Area of square with side equal to diameter :

$A_s=D^2\\\\A_s=(\dfrac{31}{3})^2\\\\A_s=106.78\ inch^2$

Since , the area of square is more than area of pizza .

Therefore , pizza can easily be fitted .

Hence , this is the required solution .
