Assume each square is 1 unit.
The base of the large triangle is 6 units and the base of the smaller triangle is 3 units.
The scale factor is 1/2
Distance Rate times Time
320= R 5.25
R= 60.9
R= 61 mph
Answer:
It is the <em><u>second one</u></em>
Step-by-step explanation:
1st option does not include the number 2 from the equation above,
and 3 and 4, you do not have to divide anywhere in the equation, so those are no possibly correct.
So, when adding in the 7 and 3 the new equation is:
9{(9x7)+(4x3)+9}
Following pemdas, you have to do parenthesis first. So now the equation is:
9(63+12+9)
Now distribute the 9:
567 + 108 + 81
And finally solve as a normal addition problem:
567 + 108 + 81= 756
So, the answer is 756.
I hope this helps:)
