Answer:
C, x + 20 = 41
Step-by-step explanation:
X represents the number of small sea shells that we originally had. When the family adds 20 more shells, that makes x + 20. The total number is 41, so that means the number of sea shells they already had (x) plus the number of sea shells they collected (20) equals the number of shells they have now (41).
Answer:
its A.
Step-by-step explanation:
Answer:
26 cm
Step-by-step explanation:
we can make an equation to find the lengths
2(x+7x-2) = 60
x : length of width
7x-2 : the length of length
2 : the two pairs of length and width
solving this equation, we get x = 4
but that is not the answer
we have to plug in x=4 into 7x-2
7*4-2 = 28-2 = 26
