Diana received 300 votes in the election for student council president. That was 60% of the students who voted in the election.

Helen [10]

Answer:

500 students.

Step-by-step explanation:

300 votes is 60%.

100%-60% is 40%

so 40% voted for the other person.

Work backwards:

x * 0.6=300

0.6x=300

x=300/0.6 which is 500.

500*0.4 is 200.

300+200 is 500.

Hope this helps :) I am terribly sorry if it is wrong or not using the number line.

Solving quadratic equations by factorization: 2x^2+5x-7=0 (step by step)

ch4aika [34]

Answer:

x = 1 ; x = -7/2

Step-by-step explanation:

$2x^2 + 5x - 7=0\\=> 2x^2 - 2x + 7x - 7=0\\=> 2x(x - 1) + 7(x - 1)=0\\=> (x - 1) (2x + 7)=0\\$

Here the sol. of x =

1) x - 1 = 0

=> x = 1

2) 2x + 7 = 0

=> 2x = -7

=> x = -7/2
