"twelve decreased by twice a number" ---> 12 - 2x
"8 times the sum of number and 4" ---> 8(x + 4)
12 - 2x = 8(x + 4)
12 - 2x = 8x + 32 (distributive property)
12 = 10x + 32 (add 2x to both sides)
-20 = 10x (subtract 32 from both sides)
x = -2 (divide both sides by 10)
That's answer.
Answer:
29/30
Step-by-step explanation:

220+12/240
232/240 ........divide it by 8
29/30
Y = -4x + 7
This is the equation of the line. The slope is -4. The Y- intercept is 7
Answer:
The total amount of money pays by Adrian is $14.5 .
Step-by-step explanation:
As given
Adrian purchases six tubes of paint and three paint brushes at a craft store.
Each tube of paint cost $2.50 each paint brush cost $0.50 .
Total cost of the 6 tubes of paints and 3 paint brushes = 6 × Cost of each tube of paint + 3 × Cost of each paint brush cost .
Putting the values in the above
Total cost of the 6 tubes of paints and 3 paint brushes = 6 × 2.50 + 0.50 × 3
= 15 + 1.5
= $16.5
As given
Adrian has a coupon for $2 of his purchase .
Total amount money pay by Adrian = Total cost of the 6 tubes of paints and 3 paint brushes - Coupon cost
Putting the values in the above
= $16.5 - $2
= $ 14.5
Therefore the total amount of money pays by Adrian is $14.5 .
