Answer:
The 4th one
Step-by-step explanation:
No X intercepts overlap
Answer:
35 dogs
Step-by-step explanation:
x ---> the number of dogs
y ---> the number of cats
The last week of January we have 20 cats and the ratio is the same
so
\frac{x}{y}=\frac{49}{28} ----> equation A
y=20 ---> equation B
substitute equation B in equation A
\frac{x}{20}=\frac{49}{28}
solve for x
x=\frac{49}{28}(20)=35 dogs
Answer:
Degree of length: 1
Degree of width: 1
Degree of height: 3
Degree of volume: 5
Explanation:
The degree, for example, is the 2 in 3x²-1 or the 3 in x³·5x²-4. Because the highest exponent in the equation determines the degree or something like that so yea i got u fam.
IF -2/5 + -1/4 IS IN PARENTHESES:
skip this part if its not
(1/2) / (-2/5 - 1/4)
(-2/5 - 1/4) is equivalent to (-8/20 - 5/20) = -13/20
substitute -13/20 for (-2/5 - 1/4)
1/2 / -13/20
remember that division is the inverse of multiplication, so if we flip the second fraction, we can change the division sign to multiplication (when doing this, never flip the first fraction, you will not get the right answer)
1/2 * -20/13
simplify -20/2 to get -10
1 * -10/13 = <u>-10/13</u>
IF -2/5 + -1/4 IS NOT IN PARENTHESES:
1/2 / -2/5 +-1/4
PEMDAS : multiplication/division comes before addition / subtraction
1/2 / -2/5 = (apply the flip rule : read the chunk of text above if you don't know what it is) 1/2 * -5/2 = -5/4
subtract 1/4 form -5/4 now
-5/4 - 1/4 = -6/4
simplify
= <u>-3/2</u>
