Answer: question 1: 20 question 2: 21 question 3: 17, 19, 23
Step-by-step explanation:
I’m not sure if this is correct but this is the way i would solve it.
first, make an equation with the given information
2x-3=30
Then, add three to both sides
2x=33
Finally, divide both sides by 2
x= 16.5
x represents the age of maggie so all you have to do is plug the solution into the equation to check your answer.
2(16.5)-3= 30
Answer:
The answer for 3/7 x 28 is 12.
Step-by-step explanation:
Ratio of men to women: 21:28, also simplified as 3:4
Ratio of women to the total number of people: 28:49 which is also 4:7
Answer:
y = -3x - 8.3
Step-by-step explanation:
You need to rearrange 9x + 3y = -22 in the form y = mx+c.
9x+3y = -22
3y = -9x - 22
y = -3x - 7.3
As long as the gradient is the same, the lines will be parallel. So you can give any number to the intercept (in this case I gave 8.3) and you will have parallel equations.
Final answer : y = -3x - 8.3
