Answer:
Step-by-step explanation:
If all 21 coins were dimes, she'd have $2.10. But she has 90 more cents than that. Now for each coin that's a quarter, not a dime, she has 15 cents more. 90/15= 6. So there are 6 quarters, and 21-6 = 15 dimes.
Now we do it backwards to see if it's right. 6 quarters is $1.50, 15 dimes is $1.50, add those together and you get $3. So it's right. 6 quarters, 15 dimes.
ANSWER
y = 100 + 0.25(160) - equation
y = 140 - if you needed the answer
7/21 or 1/3rd, it's just a ratio of white to all, there's 7 white straws and 21 in all, then you can simplify it down to 1/3rd.
Answer:
Reflection across y axis
Translate up by 3 units
Step-by-step explanation:
Given


Required
Describe the transformation from f(x) to g(x)
First, take a reflection of f(x) across the y axis.
So f(x) becomes f(-x)
when reflected

Next, translate f(-x) up by 3 units to give g(x)

Where




Hence, the transformation from f(x) to g(x) includes:
Reflection across y axis
Translate up by 3 units
