2×x=6 is this positive or negative?

Solnce55 [7]

Hey there!

Since,

$\bold{2=positive}$
$\bold{x=positive}$
$\bold{6=positive}$

Since, all of your terms are all positives, this means your answer will most likely be a $\boxed{\boxed{\bold{POSITIVE}}}$ .. $\bold{(+)}$

If you see a minus sign/ negative symbol $\bold{(-)}$ in front of the numbers then it will make them a negative

Good luck on your assignment and enjoy your day!

Julio has 5 more dollars than Dan. Altogether, Julio and Dan have $19. Write and solve an equation to represent the situation. H

cluponka [151]

Answer:

Dan has $7 and Julio has $12

Step-by-step explanation:

Julio = x

Dan = y

They both have a total of $19:

x + y = 19

Julio has 5 more dollars than Dan:

(Therefore Dan would need 5 more dollars to catch up to what Julio has)

y + 5 = x

We now plug in one equation into the other and get:

y + (y+5) = 19

2y+5 = 19

2y = 14

y = 7

Plug in Dan's amount into the initial equation and we get:

7+5 = x

x =12

HELP- Picture Included

1000 mg = 1 g
the prefix "milli" means "thousandth", which is why there are 1000 mg in one gram

Use that equation above as the conversion factor
3500 mg = (3500 mg)*(1 g/1000 mg) = (3500/1000) g = 3.5 g

So in short,
3500 mg = 3.5 g

Answer: 3.5
