Answer:
y = -2/5x + 3
Step-by-step explanation:
Start with your given:
2x + 5y = 15
Isolate y:
5y = -2x + 15
Divide 5 on both sides:
y = -2/5x + 3
Hope that helped. Hang in there! :)
I believe this answer to be true. This can be said because 4/2 equals 2 as does 24/12. Both of those fractions equals 2 yet they are two completely different fractions. Please tell me if I was right lol.
Answer:
Maximum number of children among whom 32 red marbles, 144 blue marbles and 176 green marbles can be divided equally is 16.
Step-by-step explanation:
Finding HCF of 32, 144, 176
32 = 2 * 2 * 2 * 2 * 2
144 = 2 * 2 * 3 * 2 * 2 * 3
176 = 2 * 2 * 2 * 11 * 2
HCF = 2 * 2 * 2 * 2 = 16
Answer: x is 12
Step-by-step explanation:
For directly proportional relationship, both variables change in the same direction. It means that an increase in one variable will result to an increase in the other variable. A decrease in one variable will result to a decrease in the other variable.
y and x have a proportional relationship,
We will introduce a proportionality constant and replace the proportionality symbol with an equal to symbol. Thus
y = kx
When y is 12, x is 8
Substituting into the equation,
12 = k × 8
k = 12/8 = 1.5
The equation becomes
y = 1.5x
The value of x when y is 18 will be
18 = 1.5x
x = 18/1.5 = 12
