5y-5=22
or
5(y)-5=22
Hope that helps!
Just let me know if you want to know what y equals.
I'm not sure how the correct way to do this would be but if you have a ratio that is 5:2 think of it as having 5 groups of animals and 2 groups of animals.
Find the number by dividing the total amount of animals 98/7 = 14.
We know that there are 5 groups of cats, the ratio for 5 cats. 14 x 5 = 70.
The remainder is dogs, which has a ratio of 2:5. 14 x 2 = 28.
70 + 28 = 98.
Answer:
(7, 0 )
Step-by-step explanation:
Given the 2 equations
y = - 2x + 14 → (1)
y = 2x - 14 → (2)
Since both equations express y in terms of x we can equate them
2x - 14 = - 2x + 14 ( add 2x to both sides )
4x - 14 = 14 ( add 14 to both sides )
4x = 28 ( divide both sides by 2 )
x = 7
Substitute x = 7 into (2) for corresponding value of y
y = (2 × 7) - 14 = 14 - 14 = 0
Solution is (7, 0 )
The point that is 3/7 of the way between -4 and 17 is 5
