If the ratio is 1:2,
sam has three dollars.
buffy has six dollars.
we know this because the ratio is 1;2, so we can multiply sam’s amount by two, because buffy’s amount is twice sam’s amount.
ANSWER: buffy has 6 dollars!!
if you need the new ratio: 3:6
Answer:
Sydney is 92 years old
Step-by-step explanation:
107(the sum of both ages)-15(years older than Sydney)=92
Answer: 26
Step-by-step explanation:
Let the number be n.
Now,
twice a number =>> 2n
added to 3 =>> 2n + 3
is divided by the number plus 7 is five thirds =>> (2n + 3) / (n + 7) = 5 / 3
(2n + 3) = (5 / 3) × (n + 7)
3 × (2n + 3) = 5 × (n + 7)
6n+9 = 5n + 35
6n - 5n = 35 - 9
n = 26
Answer:
y=5/3 is the only real solution
Step-by-step explanation:
Solve for y over the real numbers:
11 y^2 - 19 y - 10 = -4 y^2
Add 4 y^2 to both sides:
15 y^2 - 19 y - 10 = 0
The left hand side factors into a product with two terms:
(3 y - 5) (5 y + 2) = 0
Split into two equations:
3 y - 5 = 0 or 5 y + 2 = 0
Add 5 to both sides:
3 y = 5 or 5 y + 2 = 0
Divide both sides by 3:
y = 5/3 or 5 y + 2 = 0
Subtract 2 from both sides:
y = 5/3 or 5 y = -2
Divide both sides by 5:
Answer: |
| y = 5/3 or y = -2/5
