Answer:
x=-7, y= -20
Step-by-step explanation:
2x - y =6
x - y = 13
when I subract (x-y =13 ) from (2x-y =6)
2x -y =6
-x +y=-13
______________
x = -7
substitute x=-7 in the second equation
-7 - y =13
-y = 13 +7
-Y = 20
Y=-20
x=-7, y= -20
Answer:
A. 13%
Step-by-step explanation:
let's suppose there's 1000 bars of chocolate in general
70 % dark = 700 dark choco bars
30 % milk = 300 milk choco bars
20 % have nuts = 200 bars have nuts
80 % don't have nuts = 800 bars don't have nuts
if 90 % of dark chocolate bars don't have nuts, that means 630 dark chocolate bars don't have nuts, but 70 have nuts
200 bars in general have nuts, if only 70 dark chocolate bars have nuts,
200 - 70 = 130
130 = 13%
Answer:
720ft²
Step-by-step explanation:
Wall 1&2 = lh = 15*10=150
Wall 3&4 = wh = 12*10=120
Ceiling = lw = 12*15=180
120+150+120+150+180=720ft²
Answer:
$2.00
Step-by-step explanation:
If Zak is Buying 6 gallons, and he has a coupon for each gallon for $0.55 off, we need to first find how much he saved.
We can do this by calculating $0.55 (or 0.55) multiplied by 6. This answer is 3.30, or $3.30.
Now we add $3.30 to $8.70 to get the normal price for 6 gallons of fruit punch.
3.30 + 8.70 = 12.00, or $12.00
The normal price for 6 gallons of fruit punch is $12.00.
Now, we divide 12 by 6 to get the cost of one single gallon of fruit punch.
12/6 = 2
One gallon of fruit punch costs $2.00
Hope this helps! Have a great rest of your day! :)
