Isabel received 4/7 of the 210 votes for cast for class treasurer. How many votes did she receive? Write your answer in simplest
KengaRu [80]

Answer:

120 votes

Step-by-step explanation:

So one way to solve this is by creating an equation to solve for x.

So we are given 4/7, that will be one side of the equation.  

And we are trying to figure out how many votes out of the 210 she received, so on the other side of the equation we will have x/210, since we are solving for x.  

So 4/7 = x/210

We want to get x alone, so we can multiply 4/7 by 210, which equals 120.

So x equals 120!

Solve for b. 5 + 2b = 9 Show your work for each step as you solve for b.
Dahasolnce [82]

Answer:

\boxed{\sf{b=2}}

Step-by-step explanation:

Isolate the b from one side of the equation.

<u>First, subtract by 5 from both sides.</u>

\sf{5+2b-5=9-5}

<u>Solve.</u>

<u />

<u>Subtract.</u>

9-5=4

2b=4

<u>Divide by 2 from both sides.</u>

2b/2=4/2

<u>Solve.</u>

<u />

<u>Divide the numbers from left to right.</u>

4/2=2

\Longrightarrow \boxed{\sf{b=2}}

Therefore, the correct answer is b=2.

I hope this helps, let me know if you have any questions.

What two numbers can be used in place of the? To make the statement true.<br><br> I?I =8/9
bogdanovich [222]
Since the absolute value makes numbers absolute or real numbers you could replace the ? with 8/9 or -8/9 since the negative will go away because of the absolute value sign.
