Ava's family took a road trip to Niagrara Falls. Ava slept through the last 65% of the trip. If Ava fell asleep after they had travelled 203 miles, what was the total length of
the trip?

x = 580

Step-by-step explanation:

?+65=100

?=100-65

100-65=35

?=35

Part/whole = percent/100

X= whole

203/x = 35/100

Solve for x:

100•203 = 35•x

Divide both sides by 35

20300/35 = 35x/35

X=580

Or

35% in decimal form is 0.35 Bc you are dividing 35 by 100.

0.35x = 203

0.35x/0.35 = 203/.35

X=580

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
