Answer: Hello there!

the inequality is (i think):

5x - 2y + 1 > 0

and we wanna see if the point (-2, -1) satisfies this inequality.

If we want to see it, we just need to replace the values x= -2, y = -1 in the inequality and see if it is satisfied:

5x - 2y + 1 > 0

5*(-2) - 2*(-1) + 1 > 0

-10 + 3 > 0

-7 > 0

this is false; then the point (-2, -1) does not satisfy the inequality.

2y < 5x + 1
y < 5/2x + 1/2

x = - 0.2
y = 1/2

the point is false

Lena found a 5/8
DENIUS [597]

Answer:

Naomi had the correct measurement the ring weighed 0.625 carats

Step-by-step explanation:

* The diamond ring weighed 5/8 carats

- To know who is right lets change the fraction 5/8 to a decimal number

∵ 5/8 means 5 ÷ 8

- 5 is smaller than 8 so we will multiply it by 10 and

 insert decimal point in the quotient (answer of division)

∴ It will be 50 ÷ 8 = 6 and remainder 2/8 ⇒ 1/4

∴ The quotient = 0.6 and remainder 1/4

- 1 is smaller than 4 so we will multiply it by 10

∴ It will be 10 ÷ 4 = 2 and remainder 2/4 ⇒ 1/2

∴ The quotient = 0.62 and remainder 1/2

- 1 is smaller than 2 so we will multiply it by 10

∴ It will be 10 ÷ 2 = 5 without remainder

∴ The quotient = 0.625

* Naomi had the correct measurement the ring weighed 0.625 carats
