Answer:
11=DE
Step-by-step explanation:
3x-28+3x-30+x=33
7x-58=33
7x=91
x=13
3(13)-28

Yes, 0.003 is 1/10 of 0.03, since 0.03/10=0.003. A good trick to answer these problem is to add another 0 while you are in the decimals, dividing by 10.
Answer:
I thing option A. all real numbers.
but IAM not exactly sure....
Let s represent the short side of the triangle. The long sides of the triangle are each s+1, and the triangle's perimeter is
... s + (s+1) + (s+1) = 3s+2
The length of one side of the square is s-2, and its perimeter is 4 times that, 4(s-2) = 4s-8. The square and triangle have the same perimeter, so
... 3s+2 = 4s-8
... 10 = s . . . . . . . . add 8-3s to both sides
The length of the shorter side of the triange is 10 units.
Answer:
10 miles per hour
Step-by-step explanation:
there are 60 minutes in an hour once you covert you have that it took 1.17 hours then there are 5280 feet in a mile so you convert and get 12.075 miles
you divide
12.075/1.17 = 10.3205128
then you simplify to the nearest whole number and get 10
