6 0

Answer:

a) \frac{32}{21}

b) -14

c) -3

d) -96

Step-by-step explanation:

a) The parenthesis indicate multiplication.

b) Minus and plus gives subtraction, and the sign you put behind the number is the sign of the largest number you have (in this case it's 21 since we ignore the -)

c) They already have common denominators, all that's left is to do \frac{-7 -2}{3} = \frac{-9}{3} = -3

d) The parenthesis indicate multiplication.

Good luck!

Why can you use cross products to solve the proportion 18/5 = x/100 for x ?
Tcecarenko [31]

Answer:

Yes, you can use cross products to solve for x in this proportion. Also, x is 360.

Step-by-step explanation:

Yes, you can use cross products to solve for x in that proportion.

Here's how you do it :

\frac{18}{5} = \frac{x}{100}

We cross product, getting :

18 * 100 = 5 * x

1800 = 5x

Divide by 5 on both sides to get x by itself.

360 = x

Yes, you can use cross products to solve for x in this proportion. Also, x is 360.
