answer
width = 98 cm
length = 105 cm
set up equations
the perimeter of a rectangle = 2W + 2L
p = 2W + 2L
the perimeter is also 406
406 = 2W + 2L
we know that the length of the rectangle is 7 cm longer than the width so
L = W + 7
substitute equations and solve for width
plug L into p = 2W + 2L to get
406 = 2W + 2(W + 7) distribute the 2 to the terms in the parentheses
406 = 2W + 2W + 14
406 = 4W + 14
392 = 4W
W = 98
substitute equations and solve for length
now that we know the width, we can substitute W in L = W + 7 to find length
L = W + 7
L = 98 + 7
L = 105
final dimensions
width = 98 cm
length = 105 cm
Answer:
29
Step-by-step explanation:
Put 8 where n is, then do the arithmetic.
C(8) = -6 +5(8 -1) = -6 +5(7) = -6 +35
C(8) = 29
Answer:
Step 1: Calculate the change by subtracting old cost ($52) from the new cost ($64)
Step 2: Divide that change by the old cost ($52). You will get a decimal number
Step 3: Convert the decimal number to a percentage by multiplying by 100%
Answer:
73
Step-by-step explanation:
647 - 574
1.) subtract 7 -4 and you get 3 in the ones place.
2.) next you have to do 4 -7 and you can't do that so you take one from the hundreds place and turn the 6 into a 5.
3. make the 4 a 14 and then subtract 14-7 and you get 7 in the tens place
4.) you are then left with 5-5 in the hundreds place which is 0 so your answer is 73
