Answer:a=130,b=50

Step-by-step explanation:

a+b= 180

2a-5b=10

2(180-b)-5b=10 (I have substituted (180-b) for a here.)

360-2b-5b=10

350=7b

b=50

a+50=180

a=130

Answer:

50 questions

Step-by-step explanation:

Given the following question:

92% of 50

To find the answer we have to use the formula to calculate percentage.

$\frac{p\times n}{100}$
$\frac{92\times50}{100} =92\times50=4600\div100=46$
$=46$

Which means in total there was "50 questions" on the test.

Hope this helps.
