Answer:x=4

Step-by-step explanation:

tendrías que poner términos similares juntos, asegurándote de cambiar el signo de cualquier figura que cruce el igual al signo. luego restarías o sumarías, resolverías las ecuaciones de cada lado, ya que ahora están agrupadas. luego dividirás tu respuesta por el coeficiente que es 2 (2x). esto te dejaría con 4

4x - 2x = 1+7

4x-2x= 8

2x =8

divisir

x=8

The value of the digit in the hundredths place of 0.44 is how many times as much as the value of the digit in the tenths place
dangina [55]
The hundreths place of 0.44 is the second 4, aka 0.4(4) <-- this digit.
The digit in the tenths place is 0.(4)4 <--- the one circled by the brackets.

So the value of the digit in the hundreths place is 0.04, while the value of that in the tenths place is 0.4~

You should be able to get to the answer from here, if not, I'll be here to answer/follow through~ :)

The expressions a(8x+7) and 4x+3.5 are equivalent. What is the value of a?
valentina_108 [34]

Answer:

a=1/2

Step-by-step explanation:

From the question, the expression a(8x+7) is equivalent to 4x+3.5

     Which means that multiplying 8x by a gives 4x and multiplying 7 by a gives 3.5

So, we can write the following to find the value of a

a(8x+7)\equiv 4x+3.5

we can write the following

8ax=4x

\implies a=\frac{4x}{8x}= \frac{1}{2}

Hence the value of a is 1/2
