3 (a - 1) + 31 - 11a = 4 ( 2a + 3)

nikitadnepr [17]

Answer:

-⅖

Step-by-step explanation:

We need to simplify the given equation and find out the value of a , as ,

=> 3(a-1)+31-11a = 4(2a+3)

=> 3a -3+31-11a = 8a + 12

=> -8a -28 = 8a + 12

=> 16a = -28-12

=> 16a = -40

=> a = -2/5

<h3>• Hence the value of a is -⅖ .</h3>

Cloud [144]

Answer:

80 countries participated in the 1980 olympics in Moscow.

Step-by-step explanation:

Hello, I think I can help you with this

You can solve this by using a simple rule of three

Step 1

define

140 countries participated in 1984,this was 75% more than the last time,this means that 140 is the 175% of a value that we need to know

140 ⇔175%

x? ⇔100%

the relation is

$\frac{140}{175}=\frac{x}{100}$

Step 2

solve for x

$\frac{140}{175}=\frac{x}{100}\\x=\frac{100*140}{175}\\x=\frac{14000}{175} \\x=80$

80 countries participated in the 1980 olympics in Moscow.

Have a nice day
