Answer:
Step-by-step explanation:
Basically you turn 1/2 into fourths, 1/2 = 2/4
After that you would multiply 4 2/4 x 2 1/4
Then you get 10.125 turned into a fraction is 81/8
9514 1404 393
Answer:
84 dogs
Step-by-step explanation:
We can multiply each of the numbers in the ratio by 12 to see the answer:
cats : dogs = 3 : 7 = 36 : 84
There were 84 dogs in the park.
The correct answer is G. y=15x+80 because y represents the total, 15x represents the number of months times 15 because it increases by 15 members every month. And then you started with 80, so there's plus 80 at the end.
Answer:
x-45=12
Step-by-step explanation:
a number equals x
difference equals -
of a number and 45 so 45 first
is equals =
12 is after is so 12
y = -x² - 2x + 3
y - 3 = -x² - 2x + 3 - 3
y - 3 = -x² - 2x
y - 3 - 1 = -x² - 2x - 1
y - 4 = -(x²) - (2x) - (1)
y - 4 = -(x² + 2x + 1)
y - 4 = -(x² + x + x + 1)
y - 4 = -(x(x) + x(1) + 1(x) + 1(1))
y - 4 = -(x(x + 1) + 1(x + 1))
y - 4 = -(x + 1)(x + 1)
y - 4 = -(x + 1)²
y - 4 + 4 = -(x + 1)² + 4
y = -(x + 1)² + 4
