Get x on one side then you can use substitution
So, change x+3y=3 to x= -3y+3
Then plug in x to other equation to find y
2(-3y +3)-3y=-12
-6y + 6 -3y = -12
-9y = -18
Divide both sides by negative nine to find y
y = 2
Then plug in to original equation to find x
x + 3(2) = 3
x + 6 = 3
x = -3
So, y = 2 and x = -3
5 pairs of gloves, two gloves per pair, so we have 10 gloves.
If the entire pack cost $29.45, we divide that by 10 to determine the cost of a single glove:
$29.45 ÷ 10 = $2.945 which rounds to $2.95 per glove.
Answer:
5
Step-by-step explanation:
she bought a soft drink for $3 so subtract that from the overall cost which is $43.
$43.00 - $3.00 = $40.00
Then I just divided that by 8 because thats how many candy bars she bought
40 ÷ 8 = 5
So each candy bar was $5.00
Hope its right
Im extremly sorry if its wrong
Answer:
-90m+74
Step-by-step explanation:
If the patch doubles in size every day, it means that yesterday it was half as large as today. So, if today (day 243) the patch is as large as the lake, yesterday (day 242) half as large, so it was as large as half the lake.
