(-3/4)*(-3/5)*(-1)= <br> pls help my teacher is gonna kill me

GaryK [48]

Answer:

-9/20

Step-by-step explanation:

For the first two terms, all you have to do is multiply the numerators and the denominators, and cancel out the negative, but because there is a -1 after that, the negative sign comes back, although the -1 doesn't really change the number.

What steps do you use to solve y=x+12 and y=-x+17 an unknown number y is 12 more than an u known number x the number y is also x

Tamiku [17]

Answer:

x=2.5

Step-by-step explanation:

Solve for x in this systems of equations, we already have two values which equal y so half the work is finished for us.

Starting with the equation:

$x+12=17-x$

Add x to both sides to remove the negative x on the right side of the equation:

$2x+12=17$

Subtract 12 from both sides to remove the 12 on the left side of the equation:

$2x=5$

Divide both sides by 2 to cancel out the x coefficient

$x=2.5$

The table shows the number of cups of water required when cooking different amounts of rice.

Vsevolod [243]

Answer:

For every 1 cup of rice, 2.5 cups of water are required.

Step-by-step explanation:

We can solve this by examining the table closely. We see that the difference of water cups required for 2 and 3 rice cups is 2.5. This stays true for 5 cups of rice. where the difference from the required water for 3 cups of rice is 5.
