Answer:
Step-by-step explanation:
5) -7 (-15w + 21) + 3(18 - 27w)
Step 2: 105w - 81w - 147 + 54
6)
step 3: 24w - 93
I think that’s it f(x)=2x−12
2a+1b=27.50
4a+2b=59.50
Multiply first equation by -4 and the second by 2 so you can drop off the a values then add the equations together. Then solve for b. You should get b=6.
Then plug b into one of the original equations and solve for a and you should get 10.75
So a plate of spaghetti is $10.75 and a salad is $6.

12y +6 is the answer to that question
Answer:
C) (14, 8, 10)
Step-by-step explanation:
the values in the parentheses go in order of the letters in the first equation
all you have to do is plug in the values
p+q+r=32. (14)+(8)+(10)=32
p-r=4. (14)-(10)=4
2p+q=36. 2(14)+(8)=36
