Answer:
5.67
Step-by-step explanation:
Let's examine both factors...
1.35 comes from 135, it's 100 times smaller, so this factor would force me to move the decimal point by 2 positions to the left.
4.2 comes from 42, it's 10 times smaller, so this factor would force me to move the decimal point by 1 position to the left.
In total, the decimal point would have to be moved by 3 positions, to the left... so 5,670 would become 5.67
Which is easily verifiable just by looking at the end equation, even without calculating it:
1.35 * 4.2 would give something around 5... not around 50 nor 500.
Answer:
Line R, S, and P are parallel lines meaning any lines that pass through them will form the same angles. Look at 4 and 2. One line is intersecting S and P to for the same angles. Corresponding angles in parallel lines which are formed by an intersecting line are equal. Therefore 4 and 2 are equal. That leaves B, C, and D left. 4 is also congruent to 5. This is because if 4 is congruent to 2 and 2 is congruent to 5 by vertical angles theorem, 5 must be equal to 4 (transitive property of equality: is a=b and b=c then a=c)
That leaves B and D left. Notice the angle made at the very top left. Across from that unlabeled angle is 6. By vertical angles theorem those 2 angles are congruent. The unmarked angle is equal to 2 and 4 because corresponding angles in parallels are congruent. Therefore lets mark that unmarked angle as 0. If the m< 6 = m< 0 and the m<0= the m<4 then m<6 must equal the m<4.
That leaves Just B remaining thus B is NOT congruent to 4

Try using the app photo math too! It will show the work on how to do it if u have an iphone.
(3x9)x10=n x (9x10)
27 x 10=n x 90
270=90n
n=3
