Select the equation(s), where 9 is a solution. A 9+3x=36

B 57=6x+3

C 4x+3=43

D4x=49

a and b

Step-by-step explanation:

a)

9+3x=36

3x=27

x=9

b)

57=6x+3

54=6x

9=x

c)

4x+3=43

4x=40

x=10

d)

4x=49

x=12.25

85.3-64 = 21.3

so laura has already added 85.3 grams of chocolate powder and she has gone over the amount specified in the recipe by 21.3 grams

hope i ! have a great  day!

m∠abd = m∠dbc

step-by-step explanation:

given : ab bisects ∠dbc

as we know that bisection means ab divides   ∠dbc   in two equal angles named as   ∠dba and   ∠abc

so, m∠abd = m∠dbc  

because ab bisects ∠dbc.

hence , the first statement m∠abd = m∠dbc is true.
