Answer: $49\frac{7}{10}$

Turn 5 2/5 into an Improper Fraction

Multiply 5*5 and get 25. Now add 2 and get 27.

5 2/5=27/5

Turn 9 2/10 into an Improper Fraction

Multiply 9*10 and get 90. Now add 2 and get 92.

9 2/10=92/10

New problem: 27/5×92/10

Multiply

$27/5*92/10=2484/50$

Divide

$2485/50=49.7$

Turn 49.7 into a Mixed Number

$49.7=49\frac{7}{10}$

The following figures are not drawn to scale but AB and CD are straight lines. Find x

astraxan [27]

Answer:

x=45

Step-by-step explanation:

Since AB is a straight line, it is 180 degrees

AOE + EOF + FOD + DOB = 180

15+x+2x+120-2x = 180

Combine like terms

135 +x = 180

Subtract 135 from each side

135-135 +x = 180 -135

x = 45
