Answer:
25 students had soup for lunch
Step-by-step explanation:
Sandwich : soup
Of all students who purchased lunch this Thursday, 30 chose a sandwich
Let x = number of students who choose soup
Sandwich : soup = 30 : x
If the ratio of students who chose a sandwich to all of those who chose soup was 6:5
Sandwich : soup = 6 : 5
how many of the students had soup for lunch?
Equate both ratios
Sandwich : soup
30 : x = 6 : 5
30 / x = 6 / 5
Cross product
30 * 5 = x * 6
150 = 6x
Divide both sides by 6
x = 150 / 6
= 25
x = number of students who choose soup = 25 students
Answer:
x= 1/3 , -4/3
Step-by-step explanation:
9x^2 + 9x -4 =0
(3x-1) (3x+4) =0
x= 1/3 , -4/3
Enlarge means to make bigger
All you got to do is to find a number that will make the equation equal to 2.
What you could do is multiply each side by 12.
Then it will become 6x + 2x = 24
Combine like terms: 8x = 24
Now divide each side by 8
The answer is x = 3
