Mrs. kimble, the sixth-grade math teacher, asked the class to describe the relationship between two points on the number line, 7.45 and 7.5, and to create a real-world scenario. jackson writes the following story:

"two friends, jackie and jennie, each brought money to the fair. jackie brought more than jennie. jackie brought $7.45, and jennie brought $7.50. since 7.45 has more digits than 7.5, it would come after 7.5 on the number line, or to the right, so it is a greater value."

determine if you agree or disagree with the representation. then, defend your stance by citing specific details in your writing.

Jackie took less money than Jennie.  

Step-by-step explanation:

We are given the following information in the question:

Money brought by Jackie  = $7.45

Money brought by Jennie  = $7.5

It is incorrect to say that Jackie brought more money than Jennie on the basis that 7.45 has more number of digits than 7.5

The student forgot to take in consideration the 0 in 7.50 which means apart from 7 dollars, 50 cents were taken and in case of 7.45, apart from 7 dollars, 45 cents were taken.  

Hence, Jackie took less money than Jennie.

false

step-by-step explanation:

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
