Evaluate -6(x-2y) when x= -3 and y= -5<br> a. -42<br> b. 80<br> c. -80<br> d. -16
Vinil7 [7]
Simply substitute x for -3 and y for -5, creating the equation shown below:
     
     -6 (-3 - 2(-5) )
Now that you have your values set up, now you can do the math by starting off with Multiplying -2 by -5, which will get you 10. 

Now that you have the parenthesis simplified in the parenthesis, you can use the distributive property by multiplying all the numbers with -6, like so:
-6(-3+10)= 18 - 60, which simplifies to -42, in which (A) is your answer.

Darn spent half of his allowance going to the movies he washed the family car and earned six dollars what is his weekly allowanc
Gelneren [198K]

Answer:

  $10

Step-by-step explanation:

We presume the car wash pay was in addition to his allowance, so without it he would have ended with $5.

If that $5 is the half of his allowance he did not spend going to the movies, then his weekly allowance is $10.
