Step-by-step explanation:
Answer:
(2,14)
Step-by-step explanation:
so i solved this with substitution but there are other methods to solve this!
equation 1 : y = -x + 16
equation 2 : y = x + 12
solve for y in equation 1 !!
y = -x + 16
(add x on both sides)
y + x = 16
(subtract y on both sides)
x = -y + 16
equation 1 now equals : x = -y + 16
substitute equation 1 into equation 2 :)
y = (-y + 16) + 12
(add 16 + 12)
y = -y + 28
(add y on both sides)
2y = 28
(divide 2 on both sides)
y = 14
now to solve for x you can insert y !
you can use equation 1 or equation 2 to solve for x.
i'm using equation 2 :
y = x + 12
(14) = x + 12
(subtract 12 on both sides)
x = 2
therefore, the answer is (2, 14).
hope this helps :p
Answer:
46. 10+10+6+6=32
47. 10×6=60
Step-by-step explanation:
46. the formula the perimeter is length plus width, is this case 10+6. but that would only be 2 sides so you have to times that by 2... (10+6)×2
47. area equals length times width so in this case 10×6=60
Both Old Navy and Wet Seal would be the best deal, because for one pair of jeans is $8, while Marshall’s one pair of jeans is $9.75.
