So we are given that the perimeter is 106 and two problems to solve
we will write this as an equation
106 = 3x + 6
we will subtract 6 from both sides
100 = 3x
now divide by 3 to isolate the variable
we will get 33 1/3 as the x
for the second one
106 = 2x - 3
add three to both sides
109 = 2x
divide by 2 to isolate the variable
we will get 54 1/2 as the x
Hope this helps :)
Divide 20 by 100 whixh equals .2, that gives us 1%. Now do .2×20 to get 20%. so 20% of 20 is 4, meaning 4 shirts are medium sized.
By looking at this question my best bet is The third one.
Answer:
You got it wrong, its the first option
Step-by-step explanation:
Since its not asking for a consectuive EVEN or ODD integer its not
X + X+2 + X+4...
Instead its just the normal way
X + X+1 + X+2 + X+3....
SO thats the correct answer.
